Class Settings

java.lang.Object

fmpp.setting.Settings

public class Settings
extends java.lang.Object

Stores FMPP settings, loads configuration files, provides other setting handling related utilities.

Settings are typed variables identified with their case-sensitive name. When you set the value of a setting, the value object you supply must be of the correct type. See the description of the TYPE_... to see the available setting types.

Methods that change setting values have a variation that require String value(s) instead of Object(s). These methods should be used when you get the setting values from text-only sources, such as command-line option values, XML attributes or .properties file. To demonstrate the difference, assume you have string value "a, b, c". If you try to use this value for a setting of type list, the normal setter method will interpret the value as a list of length 1, that stores string "a, b, c". If you try to use the same value with the string version of the same method, it will interpret the string as a list of length 3, that stores 3 strings, "a", "b", and "c".

Notes:

• All settings you want to set/get must be defined. See define(java.lang.String, fmpp.setting.Settings.SettingType, boolean, boolean). Standard settings (the settings documented in the FMPP Manual) are initially already defined.
• If you have used an object as the value of a setting, the object must not be changed anymore.
• If a method throws SettingException, then it is ensured that the method doesn't change the Settings object. For example, with add(Map), either all settings in the map will be successfully set, or neither will be set.

You can execute the processing session described by the setting with execute().

TYPE_ANY

public static final Settings.SettingType TYPE_ANY

Any object.

Input type: Object. Known bug: null value is allowed (incorrectly), but in effect removes (un-sets) the value.

Output type: Object.

String input: any value, stored as is.

Merging: not supported.

TYPE_STRING

public static final Settings.SettingType TYPE_STRING

String setting type.

Input type: String, Number, Boolean. The last two is converted to string with toString()

Output type: String.

String input: any value, stored as is.

Merging: not supported

TYPE_INTEGER

public static final Settings.SettingType TYPE_INTEGER

Integer setting type.

Input type: Number that can be converted to Integer without loss.

Output type: Integer.

String input: any value, that can be parsed to Integer by Integer.parseInt after trimming. In additional, redundant + sign is supported.

Merging: not supported

TYPE_BOOLEAN

public static final Settings.SettingType TYPE_BOOLEAN

Boolean setting type.

Input type: Boolean.

Output type: Boolean.

String input: After trimming and converting to lower-case, "true", "false" or empty string are allowed. Empty string is interpreted as true (consider a properties file that contains a key without value).

Merging: not supported

TYPE_SEQUENCE

public static final Settings.SettingType TYPE_SEQUENCE

Sequence setting type.

Input type: List, any array, Vector. No restriction regarding the type of the list items.

Output type: List. No restriction regarding the type of the list items.

String input: TDD expression starting in list mode. If the result is a list that contains a single list, then the contained list will be used. This heuristic is used to fix this user mistake:
--some-list="[a, b, c]"
instead of:
--some-list="a, b, c"

Merging: the two lists are concatenated, with the default (inherited) value coming last.

TYPE_LOCAL_DATA_MODEL

public static final Settings.SettingType TYPE_LOCAL_DATA_MODEL

Local data model setting type. This is the same as TYPE_SEQUENCE, just if the value is given as text (string input), it defers the evaluation of the hash parameter of the case function call, and stores that as Fragment. This is required because that hash parameter may uses data loaders, which shouldn't be executed until almost all settings of the Engine are set. This also means that if you set the setting value with Java, the last parameter to the case FunctionCall must be a Fragment instead of Map, if you want to use data loaders in it.

TYPE_HASH

public static final Settings.SettingType TYPE_HASH

Hash setting type.

Input type: Map, Dictionary.

Output type: Map.

String input: TDD expression, starting in hash mode.

Merging: the two maps are added (union)

TYPE_CFG_RELATIVE_PATH

public static final Settings.SettingType TYPE_CFG_RELATIVE_PATH

"Configuration relative path" setting type.

Input type: String, FileWithSettingValue. Plain File is not allowed.

Output type: FileWithSettingValue.

String input: Any value, trimmed before converting.

Merging: not supported

TYPE_CFG_RELATIVE_PATHS

public static final Settings.SettingType TYPE_CFG_RELATIVE_PATHS

"Configuration relative paths" setting type.

Input type: Same as for TYPE_SEQUENCE, but all list items must be string or FileWithSettingValue.

Output type: Same as for TYPE_SEQUENCE, but all list items are FileWithSettingValue-s.

String input: Same as for TYPE_SEQUENCE, but all sequence items must be strings. "force strings" option is on during the TDD interpretation.

Merging: the two list are concatenated.

TYPE_UNRESOLVED_CFG_RELATIVE_PATHS

public static final Settings.SettingType TYPE_UNRESOLVED_CFG_RELATIVE_PATHS

"Unresolved configuration relative paths" setting type.

Input type: Same as for TYPE_SEQUENCE, but all list items must be strings or FileWithConfigurationBase-s.

Output type: Same as for TYPE_SEQUENCE, but all list items are FileWithConfigurationBase-s.

String input: Same as for TYPE_SEQUENCE, but all sequence items must be strings. "force strings" option is on during the TDD interpretation.

Merging: the two list are concatenated.

TYPE_DATA_MODEL

public static final Settings.SettingType TYPE_DATA_MODEL

Data model setting type.

Input type: Map, Dictionary, Fragment, private class DataList.

Output type: private class DataList extends ArrayList. The list may contains: Map, String, Fragment.

String input: TDD expression, starting in hash mode.

Merging: The tow lists are concatenated.

This type is used for the "data" setting. The hash value of that setting can't be generated until the final value of all other setting is set (because data loaders may use the other settings). This way, the value of the "data" setting is a List that records the changes made on the setting, and not a Map. The Map will be built internally based on the list when you call execute().

TYPE_HASH_OF_SEQUENCE_OF_CFG_RELATIVE_PATHS

public static final Settings.SettingType TYPE_HASH_OF_SEQUENCE_OF_CFG_RELATIVE_PATHS

Hash-of-configuration-relative-paths setting type.

Input type: Map or Dictionary, that stores a List or Vector or array, that stores strings and/or FileWithSettingValue-s. Also, the map may contains strings and/or FileWithSettingValue directly as value (instead of a list of length 1 that stores the same value).

Output type: Map of List of FileWithSettingValue-s.

String input: TDD expression, starting in hash mode.

Merging: the two maps are added (union)

Constructor Detail

Settings

public Settings(java.io.File baseDir)
         throws SettingException

Creates a new instance. The standard settings will be already defined in the new instance.

Parameters:

baseDir - the base directory used to resolve relative paths in setting names. When you load settings from a configuration file, the parent directory of the file will be used instenad, for the settings coming from the file.

Throws:

SettingException

Method Detail

define

public void define(java.lang.String name,
                   Settings.SettingType type,
                   boolean merge,
                   boolean forceStr)
            throws SettingException

Defines a new setting. No setting with the same name can already exists.

Parameters:

name - the name of the setting

type - the type of the setting

merge - specifies if when you add a new setting value, and the setting has already set, then the new and old value will be merged, or the new value will replace old value. Note that only a few setting types support merging, such as list and map.

forceStr - specifies if when parsing string values with TDD interpreter, it should be done with the "force strings" option or not.

Throws:

SettingException

isDefined

public boolean isDefined(java.lang.String name)

Returns if a setting with the given name is defined (do not mix it up with being set).

See Also:

define(java.lang.String, fmpp.setting.Settings.SettingType, boolean, boolean)

getStandardSettingNames

public static java.util.Iterator getStandardSettingNames()

Returns names of the standard (not user-defined) settings.

add

public void add(java.lang.String name,
                java.lang.Object value)
         throws SettingException

Adds a setting value. Adding means that if a setting value already exists, it will be either replaced or merged with the new value, depending on the definition of the setting. When merging, the new value has higher priority than the old value. (With lists, higher priority means being earlier in the list.)

Throws:

SettingException

See Also:

set(String, Object)

addDefault

public void addDefault(java.lang.String name,
                       java.lang.Object value)
                throws SettingException

Adds a setting value with low priority. Adding means that if a setting value already exists, it will be either kept (and thus the method call has no effect) or merged with the new value, depending on the definition of the setting. When merging, the new value has lower priority than the old value. (With lists, lower priority means being later in the list.)

Throws:

SettingException

addWithString

public void addWithString(java.lang.String name,
                          java.lang.String value)
                   throws SettingException

Same as add(String, Object), but uses string value that will be interpreted by Settings.SettingType.parse(fmpp.setting.Settings, java.lang.String, boolean). Used when the value comes from a strings-only source.

Throws:

SettingException

Same as addDefault(String, Object), but uses string value.

Throws:

SettingException

add

public void add(java.util.Map settingMap)
         throws SettingException

Adds all name-value pairs stored in the map with add(String, Object). Thus, all keys must be String-s.

Throws:

SettingException

addDefaults

public void addDefaults(java.util.Map settingMap)
                 throws SettingException

Adds all entries stored in the map with addDefault(String, Object). Thus, all keys must be String-s.

Throws:

SettingException

addWithStrings

public void addWithStrings(java.util.Properties props)
                    throws SettingException

Same as add(Map), but uses a Properties object, so the values are strings.

Throws:

SettingException

addDefaultsWithStrings

public void addDefaultsWithStrings(java.util.Properties props)
                            throws SettingException

Same as addDefaults(Map), but uses a Properties object, so the values are strings.

Throws:

SettingException

set

public void set(java.lang.String name,
                java.lang.Object value)
         throws SettingException

Sets the value of a setting. If the setting value already exists, it will be replaced (never merged).

Parameters:

name - The name of the setting. It's validated if a setting with this name is defined, otherwise it throws SettingException

value - Not null; use remove(String) to un-set a value. (Known bug: if the type is #TYPE_ANY, null will not cause error, and in effect un-set the value.)

Throws:

SettingException - If the setting name or value is not valid.

set

public void set(java.lang.String name,
                boolean value)
         throws SettingException

Convenience method for setting a Boolean value.

                throws SettingException

Sets the value of a setting if the value wasn't set yet. (The name is misleading, as if the setting value is removed later, it will not get the default value.) See set(String, Object) for the parameters and thrown exception.

Throws:

SettingException

setDefault

public void setDefault(java.lang.String name,
                       boolean value)

set

public void set(java.util.Map settingValues)
         throws SettingException

Calls set(String, Object) for each name-value pair of the Map. The change is atomic; if a SettingException occurs, no setting values are changed.

Parameters:

settingValues - Maps setting names (String-s) to setting values (non-null Object-s).

Throws:

SettingException

setDefaults

public void setDefaults(java.util.Map settingValues)
                 throws SettingException

Throws:

SettingException

setWithStrings

public void setWithStrings(java.util.Properties props)
                    throws SettingException

setDefaultsWithStrings

public void setDefaultsWithStrings(java.util.Properties props)
                            throws SettingException

Throws:

SettingException

load

public void load(java.io.File cfgFile)
          throws SettingException

Loads settings from a configuration file. The file will be interpreted as legacy properties file if its extension is cfg or properties, otherwise it will be interpreted as TDD file. The settings stored in the configuration file will be added to the this object with add(Map).

Note that meta-settings ("configurationBase" and "inheritConfiguration") will not be added to the settings object.

If the setting "configurationBase" or "inheritConfiguration" is set in this setting object, then they will override the meta-settings in the file directly loaded with this method. Files inherited by the directly loaded file, however, are not affected.

Parameters:

cfgFile - the configuration file, or the directory of the configuration file if its file name is one of the default configuration file names.

Throws:

SettingException

loadDefaults(File)

loadDefaults

public void loadDefaults(java.io.File cfgFile)
                  throws SettingException

Same as load, except that it adds the settings with addDefaults(Map).

Throws:

SettingException

See Also:

load(File)

get

public java.lang.Object get(java.lang.String name)

Gets the current value of a setting.

Parameters:

name - The name of the setting. The name won't be validated.

Returns:

The value of the setting. null if the setting is not set.

remove

public java.lang.Object remove(java.lang.String name)

Removes a setting value; after this get(String) will return null.

Returns:

the removed value, or null if there was no value stored for the setting.

See Also:

set(String, Object)

getNames

public java.util.Iterator getNames()

Lists the names of settings that were set.

execute

public void execute()
             throws SettingException,
                    ProcessingException

Executes a processing session based on the setting values. For each call of this method, a new Engine object will be internally created, and initialized based on the setting values, and then its process method will be called. The method automatically chooses between bulk and single-file processing, based on the presence of the "outputFile" setting.

Settings will go through semantical checks that are not done when you call other methods. For example, it will be checked if setting "modes" contains valid mode setter function calls, if "sourceRoot" and "outputRoot" are defined for bulk mode, if exactly 1 "sources" is defined for single-file mode, etc.

This method ignores the following settings: "logFile", "appendLogFile", "echoFormat", "quiet", "snip". It's the task of the embedding software (the front-end) to interpret these settings, at least the ones it is interested in. It usually involves adding progress listeners with addProgressListener(ProgressListener).

This method can be called for multiple times, but be aware of that for each call of this method, a new Engine object will be created and initialized, even if you didn't changed the settings since the last call. If this overhead is not acceptable in you case, you can call Engine.process(...) for multiple times within the same execute() call, by overriding the doProcessing(Engine, File[], File, File) method. Also, you can do extra engine initalization there.

Throws:

SettingException - if the settings are not correct, or can't be applied because of some errors occured. This exception, when thrown, is always thrown before the execution of the processing session is stated.

ProcessingException - if Engine.process has thrown any exception, that is, there was an error during the execution of the processing session. The message of this exception holds nothing interesting (just a static text). Call its getCause() method to get the exception that caused the termination. Note that all (so even non-checked exceptions) thrown be the engine are catched and wrapped by this exeption.

addProgressListener

public void addProgressListener(ProgressListener pl)

Adds a progress listener. The progress listener will be added to the internally used Engine object when you call execute().

See Also:

clearProgressListeners()

clearProgressListeners

                                           java.lang.Object value)

Sets an engine attribute. The attribute will be set in the internally used Engine object when you call execute().

Returns:

The previous value of the attribute, or null if there was no attribute with the given name.

getEngineAttribute

doProcessing

protected void doProcessing(Engine eng,
                            java.io.File[] sources,
                            java.io.File sourceFile,
                            java.io.File outputFile)
                     throws SettingException,
                            ProcessingException

Executes the processing session(s) on the Engine level, using the already initialized Engine object.

By overriding this method, you can

• call Engine.process(...) for multiple times, so you can do multiple processing sessions with the same already initialized Engine object.
• do extra Engine initialization.

The inital implementation of this method (that is, the implementation in the Settings class) is something like this:

 if (outputFile == null) {
     eng.process(sources);
 } else {
     eng.process(sourceFile, outputFile);
 }

Modifying the Settings object in this method has no effect on the Engine object (which is passed in as argument), since all settings are already applied on it. If you need to modify the Engine object, call its methods directly.

An implementation of this method may leak out the initialized Engine object for the caller of execute(). Also, it may does not call Engine.proccess(...), but left it for the caller (who has the out-leaked Engine object). These are extreme, but otherwise legitimate usages.

Parameters:

eng - the already initialized Engine object. You may do extra addjustments on it.

sources - the list of source files, the parameter to Engine.process(File[]). It's null if the processing session uses outputFile setting.

sourceFile - if the session uses outputFile setting, then it' the 1st parameter to Engine.process(File, File), otherwise it is null.

outputFile - if the session uses outputFile setting, then it' the 2nd parameter to Engine.process(File, File), otherwise it is null.

Throws:

SettingException

ProcessingException

getDashedName

public static java.lang.String getDashedName(java.lang.String name)

Converts mixed-case setting name to dashed form, like sourceRoot to source-root.

fixVersion08SettingNames

Throws:

SettingException
