NodeSetContext
public NodeSetContext(EvalContext parentContext, NodeSet nodeSet)
Create a new NodeSetContext.- Parameters:
parentContext
- parent contextnodeSet
- associated NodeSet

Method Detail
-
getNodeSet
public NodeSet getNodeSet()
Description copied from class:EvalContext
Returns the list of all Pointers in this context for all positions of the parent contexts. If there was an ongoing iteration over this context, the method should not be called.- Overrides:
getNodeSet
in classEvalContext
- Returns:
- NodeSet
-
getCurrentNodePointer
public NodePointer getCurrentNodePointer()
Description copied from class:EvalContext
Returns the current context node. Undefined before the beginning of the iteration.- Specified by:
getCurrentNodePointer
in classEvalContext
- Returns:
- NodePoiner
-
setPosition
public boolean setPosition(int position)
Description copied from class:EvalContext
Moves the current position to the specified index. Used with integer predicates to quickly get to the n'th element of the node set. Returns false if the position is out of the node set range. You can call it with 0 as the position argument to restart the iteration.- Overrides:
setPosition
in classEvalContext
- Parameters:
position
- to set- Returns:
- boolean
-
nextSet
public boolean nextSet()
Description copied from class:EvalContext
Returns true if there is another sets of objects to interate over. Resets the current position and node.- Overrides:
nextSet
in classEvalContext
- Returns:
- boolean
-
nextNode
public boolean nextNode()
Description copied from class:EvalContext
Returns true if there is another object in the current set. Switches the current position and node to the next object.- Specified by:
nextNode
in classEvalContext
- Returns:
- boolean
