Class AbstractPatchWriter

java.lang.Object
  uka.patch.AbstractPatchWriter

All Implemented Interfaces:

Constants

Direct Known Subclasses:

MultiplexPatchWriter, NullPatchWriter, PatchWriter

public abstract class AbstractPatchWriter

extends java.lang.Object

implements Constants

Defines encoding methods for object patches and provides methods for structuring a patch into several patch records. The encoding methods can be implemented by a subclass to define a concrete patch protocol. This class provided basic means to run-length encode unmodified parts of an object.
