Class UnionIterator

java.lang.Object
- org.apache.xml.dtm.ref.DTMAxisIteratorBase
- - org.apache.xalan.xsltc.dom.UnionIterator

Implemented Interfaces:: Cloneable, DTMAxisIterator

public final class UnionIterator

extends DTMAxisIteratorBase

UnionIterator takes a set of NodeIterators and produces a merged NodeSet in document order with duplicates removed The individual iterators are supposed to generate nodes in document order

UnionIterator

public UnionIterator(DOM dom)

addIterator

public UnionIterator addIterator(DTMAxisIterator iterator)

cloneIterator

public DTMAxisIterator cloneIterator()

Returns a deep copy of this iterator. Cloned iterators may not be restartable. The iterator being cloned may or may not become non-restartable as a side effect of this operation.
Specified by:
cloneIterator in interface DTMAxisIterator
Overrides:
cloneIterator in interface DTMAxisIteratorBase
Returns:
a deep copy of this iterator.

gotoMark

public void gotoMark()

Specified by:
gotoMark in interface DTMAxisIterator

public int next()

Specified by:
next in interface DTMAxisIterator

reset

public DTMAxisIterator reset()

Specified by:
reset in interface DTMAxisIterator
Overrides:
reset in interface DTMAxisIteratorBase
Returns:
A DTMAxisIterator which has been reset to the start node, which may or may not be the same as this iterator.

setMark

public void setMark()

Specified by:
setMark in interface DTMAxisIterator

setStartNode

public DTMAxisIterator setStartNode(int node)

Specified by:
setStartNode in interface DTMAxisIterator
