package org.apache.wicket.util.diff

The diff package implements the differencing engine that JRCS uses. The engine has the power of Unix diff, is simple to understand, and can be used independently of the archive handling functionality. The entry point to the differencing engine is class Diff.

Text is represented as Object[] because the diff engine is capable of handling more than plain ASCII. In fact, arrays of any type that implements hashCode() and equals() correctly can be subject to differencing using this library.

The MyersDiff is an implementation of Gene Myers differencing algorithm. Myers' algorithm produces optimum results (minimum diffs), but consumes considerable amount of memory, it may not be suitable for very large files.
