Interface LocalDataBuilder

All Known Implementing Classes:

BshLocalDataBuilder, CachingLocalDataBuilder, MapLocalDataBuilder, TddHashLocalDataBuilder

public interface LocalDataBuilder

Contains callback to build the local data for a file processing. This interface is used to implement the "localData" setting.

Life-cycle: These are long-lived objects. The local data builder object is plugged into the Engine, and then it may be in use during several processing sessions. Typically the construction of the object is done by Settings.execute(), based on the value of setting "localData".

Local data builders that are added with setting "localData" (or directly with Engine.addLocalDataBuilder(int, java.lang.String, fmpp.LocalDataBuilder)) receive notifications about the events of the Engine if they implement interface ProgressListener.

Method Summary

java.util.Map

build(Engine eng, TemplateEnvironment env) Returns the variables that could be added to the local data.
