NodeSetContext
Constructs a new NodeSetContext.- Parameters:
parentContext- parent contextnodeSet- associated NodeSet

Method Details
-
getCurrentNodePointer
Description copied from class:EvalContextReturns the current context node. Undefined before the beginning of the iteration.- Specified by:
getCurrentNodePointerin classEvalContext- Returns:
- NodePoiner
-
getNodeSet
Description copied from class:EvalContextReturns 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:
getNodeSetin classEvalContext- Returns:
- NodeSet
-
nextNode
Description copied from class:EvalContextReturns true if there is another object in the current set. Switches the current position and node to the next object.- Specified by:
nextNodein classEvalContext- Returns:
- boolean
-
nextSet
Description copied from class:EvalContextReturns true if there is another sets of objects to interate over. Resets the current position and node.- Overrides:
nextSetin classEvalContext- Returns:
- boolean
-
setPosition
Description copied from class:EvalContextMoves 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:
setPositionin classEvalContext- Parameters:
position- to set- Returns:
- boolean
