com.sun.xml.ws.api.pipe.PipeClonerImpl

public class PipeClonerImpl
extends PipeCloner

Clones the whole pipeline.

Since Pipes may form an arbitrary directed graph, someone needs to keep track of isomorphism for a clone to happen correctly. This class serves that role.

Description copied from class: TubeCloner

This method must be called from within the copy constructor to notify that the copy was created.

When your pipe has references to other pipes, it's particularly important to call this method before you start copying the pipes you refer to, or else there's a chance of inifinite loop.

Specified by:

add in class TubeCloner

copy

public <T extends Tube> T copy(T t)

Description copied from class: TubeCloner

Invoked by a Tube.copy(com.sun.xml.ws.api.pipe.TubeCloner) implementation to copy a reference to another pipe.

This method is for Tube implementations, not for users.

If the given tube is already copied for this cloning episode, this method simply returns that reference. Otherwise it copies a tube, make a note, and returns a copied tube. This additional step ensures that a graph is cloned isomorphically correctly.

(Think about what happens when a graph is A->B, A->C, B->D, and C->D if you don't have this step.)

Specified by:

copy in class TubeCloner

Parameters:

t - The tube to be copied.

Returns:

The cloned tube. Always non-null.
