Method Detail

nextNode
public int nextNode()
Returns the next node in the set and advances the position of the iterator in the set. After aDTMIterator
has setRoot called, the first call tonextNode()
returns that root or (if it is rejected by the filters) the first node within its subtree which is not filtered out.- Specified by:
nextNode
in interfaceDTMIterator
- Specified by:
nextNode
in classLocPathIterator
- Returns:
- The next node handle in the set being iterated over, or
DTM.NULL
if there are no more members in that set.
-
asNode
public int asNode(XPathContext xctxt)
Return the first node out of the nodeset, if this expression is a nodeset expression.- Overrides:
asNode
in classLocPathIterator
- Parameters:
xctxt
- The XPath runtime context.- Returns:
- the first node out of the nodeset, or DTM.NULL.
-
getLastPos
public int getLastPos(XPathContext xctxt)
Get the number of nodes in the node list, which, in the XSLT 1 based counting system, is the last index position.- Specified by:
getLastPos
in interfaceSubContextList
- Overrides:
getLastPos
in classLocPathIterator
- Parameters:
xctxt
- The XPath runtime context.- Returns:
- the number of nodes in the node list.
