Class SiblingEnumeration

final class SiblingEnumeration extends AxisIteratorImpl implements LookaheadIterator

This class supports both the child:: and following-sibling:: axes, which are identical except for the route to the first candidate node. It enumerates either the children or the following siblings of the specified node. In the case of children, the specified node must always be a node that has children: to ensure this, construct the enumeration using NodeInfo#getEnumeration()
Constructor Summary
SiblingEnumeration(TinyTree tree, TinyNodeImpl node, NodeTest nodeTest, boolean getChildren)
Return an enumeration over children or siblings of the context node
Method Summary
SequenceIteratorgetAnother()
Get another enumeration of the same nodes
intgetProperties()
booleanhasNext()
Test whether there are any more nodes to come.

Constructor Detail

SiblingEnumeration

SiblingEnumeration(TinyTree tree, TinyNodeImpl node, NodeTest nodeTest, boolean getChildren)
Return an enumeration over children or siblings of the context node

Parameters: tree The TinyTree containing the context node node The context node, the start point for the iteration nodeTest Test that the selected nodes must satisfy, or null indicating that all nodes are selected getChildren True if children of the context node are to be returned, false if following siblings are required

Method Detail

getAnother

public SequenceIterator getAnother()
Get another enumeration of the same nodes

getProperties

public int getProperties()

hasNext

public boolean hasNext()
Test whether there are any more nodes to come. This method is used only when testing whether the current item is the last in the sequence. It's not especially efficient, but is more efficient than the alternative strategy which involves counting how many nodes there are in the sequence.

Returns: true if there are more items in the sequence

next

public Item next()
