items. | | protected void | init(Chunk orig, Chunk rev)
Initializaes the delta with the given chunks from the original and
revised texts. | | public static Delta | newDelta(Chunk orig, Chunk rev)
Returns a Delta that corresponds to the given chunks in the original and
revised text respectively. | | final public void | patch(List target)
