Examples of SVNDeltaGenerator

org.tmatesoft.svn.core.io.diff.SVNDeltaGenerator
The SVNDeltaGenerator is intended for generating diff windows of fixed size having a target version of a file against a source one. File contents are provided as two streams - source and target ones, or just target if delta is generated against empty contents.
The generator uses the V-Delta algorithm for generating full contents delta (vs. empty) and the X-Delta algorithm for generating delta as a difference between target and non-empty source streams. @version 1.3 @author TMate Software Ltd. @since 1.2
