Method Detail

setStartNode
public DTMAxisIterator setStartNode(int node)
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.
-
setNodeType
public DTMAxisIterator setNodeType(int type)
Set the node type of the parent that we're looking for. Note that this does _not_ mean "find the nearest ancestor of this type", but "yield the parent if it is of this type".- Parameters:
type
- extended type ID.- Returns:
- ParentIterator configured with the type filter set.
-
next
public int next()
Get the next node in the iteration. In this case, we return only the immediate parent, _if_ it matches the requested nodeType.- Returns:
- The next node handle in the iteration, or END.
