Specified by:

copy in interface FTIteratorInterface

Parameters:

parentIterContext - The new parent context

prevParentIterContext - The previous context of the parent iterator

copyContext - Copy the context or use the parent context

Returns:

A copy of this Iterator

Throws:

MXQueryException

getContext

public Context getContext()
