      org.apache.xalan.xsltc.dom.CachedNodeListIterator

All Implemented Interfaces:

java.lang.Cloneable, DTMAxisIterator

public final class CachedNodeListIterator
extends DTMAxisIteratorBase

CachedNodeListIterator is used for select expressions in a variable or parameter. This iterator caches all nodes in an IntegerArray. Its cloneIterator() method is overridden to return an object of ClonedNodeListIterator.

Constructor Detail

CachedNodeListIterator

public CachedNodeListIterator(DTMAxisIterator source)

Method Detail

setRestartable

public void setRestartable(boolean isRestartable)

Description copied from interface: DTMAxisIterator

Set if restartable.

Specified by:

setRestartable in interface DTMAxisIterator

Overrides:

setRestartable in class DTMAxisIteratorBase

setStartNode

public DTMAxisIterator setStartNode(int node)

Description copied from interface: DTMAxisIterator

Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Parameters:

node - Sets the root of the iteration.

Returns:

A DTMAxisIterator set to the start of the iteration.

next

public int next()

Description copied from interface: DTMAxisIterator

Get the next node in the iteration.

Returns:

The next node handle in the iteration, or END.

getPosition

public int getPosition()

Specified by:

getPosition in interface DTMAxisIterator

Overrides:

getPosition in class DTMAxisIteratorBase

Returns:

The position of the current node within the set, as defined by XPath. Note that this is one-based, not zero-based.

getNodeByPosition

public int getNodeByPosition(int pos)

Description copied from class: DTMAxisIteratorBase

Return the node at the given position.

Specified by:

getNodeByPosition in interface DTMAxisIterator

Overrides:

getNodeByPosition in class DTMAxisIteratorBase

Parameters:

pos - The position

Returns:

The node at the given position.

getNode

public int getNode(int index)

cloneIterator

public DTMAxisIterator cloneIterator()

Description copied from class: DTMAxisIteratorBase

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 class DTMAxisIteratorBase

Returns:

a deep copy of this iterator.

reset

public DTMAxisIterator reset()

Description copied from interface: DTMAxisIterator

Resets the iterator to the last start node.

Specified by:

reset in interface DTMAxisIterator

Overrides:

reset in class 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()

Description copied from interface: DTMAxisIterator

Remembers the current node for the next call to gotoMark().

gotoMark

public void gotoMark()

Description copied from interface: DTMAxisIterator

Restores the current node remembered by setMark().
