Constructor Detail

ArrayNodeListIterator

public ArrayNodeListIterator(int[] nodes)

Method Detail

next

public int next()

Description copied from interface: DTMAxisIterator

Get the next node in the iteration.

Specified by:

next in interface DTMAxisIterator

Returns:

The next node handle in the iteration, or END.

reset

public DTMAxisIterator reset()

Description copied from interface: DTMAxisIterator

Resets the iterator to the last start node.

Specified by:

reset in interface DTMAxisIterator

Returns:

A DTMAxisIterator, which may or may not be the same as this iterator.

getLast

public int getLast()

Specified by:

getLast in interface DTMAxisIterator

Returns:

the number of nodes in this iterator. This may be an expensive operation when called the first time.

getPosition

public int getPosition()

Specified by:

getPosition in interface DTMAxisIterator

Returns:

The position of the current node in the set, as defined by XPath.

setMark

public void setMark()

Description copied from interface: DTMAxisIterator

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

Specified by:

setMark in interface DTMAxisIterator

gotoMark

public void gotoMark()

Description copied from interface: DTMAxisIterator

Restores the current node remembered by setMark().

Specified by:

gotoMark in interface DTMAxisIterator

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.

Specified by:

setStartNode in interface DTMAxisIterator

Parameters:

node - Sets the root of the iteration.

Returns:

A DTMAxisIterator set to the start of the iteration.

getStartNode

public int getStartNode()

Description copied from interface: DTMAxisIterator

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

Specified by:

getStartNode in interface DTMAxisIterator

Returns:

The root node of the iteration.

isReverse

public boolean isReverse()

Specified by:

isReverse in interface DTMAxisIterator

Returns:

true if this iterator has a reversed axis, else false.

cloneIterator

public DTMAxisIterator cloneIterator()

Specified by:

cloneIterator in interface DTMAxisIterator

Returns:

a deep copy of this iterator. The clone should not be reset from its current position.

setRestartable

public void setRestartable(boolean isRestartable)

Description copied from interface: DTMAxisIterator

Set if restartable.

Specified by:

setRestartable in interface DTMAxisIterator

getNodeByPosition

public int getNodeByPosition(int position)

Description copied from interface: DTMAxisIterator

Return the node at the given position.

Specified by:

getNodeByPosition in interface DTMAxisIterator

Parameters:

position - The position

Returns:

The node at the given position.
