Method Detail

createCopy

protected VirtualCopy createCopy(NodeInfo node,
                                 NodeInfo root)

Method to create the virtual copy of a node encountered when navigating. This method is separated out so that it can be overridden in a subclass.

Overrides:

createCopy in class VirtualCopy.VirtualCopier

Parameters:

node - the node to be copied

root - the root of the tree

Returns:

the virtual copy

getAnother

public SequenceIterator getAnother()

Specified by:

getAnother in interface SequenceIterator

Specified by:

getAnother in interface UnfailingIterator

Overrides:

getAnother in class VirtualCopy.VirtualCopier

Returns:

a new iterator over the same sequence
