Constructor Detail

MultiDOM.NodeValueIterator

public MultiDOM.NodeValueIterator(DTMAxisIterator source,
                                  int returnType,
                                  java.lang.String value,
                                  boolean op)

Method Detail

isReverse

public boolean isReverse()

Specified by:

isReverse in interface DTMAxisIterator

Overrides:

isReverse in class DTMAxisIteratorBase

Returns:

true if this iterator has a reversed axis, else false

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.

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

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.

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.

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.

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().
