Class AbsoluteIterator

java.lang.Object

org.apache.xml.dtm.ref.DTMAxisIteratorBase

org.apache.xalan.xsltc.dom.AbsoluteIterator

All Implemented Interfaces:

Cloneable, DTMAxisIterator

public final class AbsoluteIterator
extends DTMAxisIteratorBase

Absolute iterators ignore the node that is passed to setStartNode(). Instead, they always start from the root node. The node passed to setStartNode() is not totally useless, though. It is needed to obtain the DOM mask, i.e. the index into the MultiDOM table that corresponds to the DOM "owning" the node. The DOM mask is cached, so successive calls to setStartNode() passing nodes from other DOMs will have no effect (i.e. this iterator cannot migrate between DOMs).

Constructor Detail

AbsoluteIterator

public AbsoluteIterator(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.

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().
