Package com.nothome.delta Description

This package contains classes for creating patches for binary files output in the GDIFF format.

The patch creation class is Delta.

The patch applier class is GDiffPatcher.

Example use:

 byte source[] = ...;
 byte target[] = ...;
 Delta d = new Delta();
 byte patch[] = d.compute(source, target);

 byte patchedSource[] = p.patch(source, patch);

 assert java.util.Arrays.equals(target, patchedSource);
