Class AbstractFXGVersionHandler

java.lang.Object

org.apache.flex.compiler.internal.fxg.sax.AbstractFXGVersionHandler

All Implemented Interfaces:

IFXGVersionHandler

Direct Known Subclasses:

FXG_v1_0_Handler, FXG_v2_0_Handler

public abstract class AbstractFXGVersionHandler
extends Object
implements IFXGVersionHandler

An abstract implementation of IFXGVersionHandler interface. It implements interfaces to encapsulate FXG version specific information. It forms the base class for the different FXGVersionHandlers. This allows the scanner to handle different versions of fxg files by swapping different FXGVersionHandlers at runtime depending on the fxg version of the input file.
