Class DocumentStreamAdapter

java.lang.Object

org.codehaus.cargo.module.merge.DocumentStreamAdapter

All Implemented Interfaces:

MergeProcessor

public class DocumentStreamAdapter
extends Object
implements MergeProcessor

Adapter class to convert streams into documents.

This is needed because the DocumentMerger understands DOM Documents, but items in War files are accessed as streams - therefore use this wrapper to pass streams into the DocumentMerger (or subclass).
