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
-
getSingleNodePointer
Description copied from class:EvalContextReturns the first encountered Pointer that matches the current context's criteria.- Overrides:
getSingleNodePointerin classEvalContext- Returns:
- Pointer
-
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
-
reset
Description copied from class:EvalContextSets current position = 0, which is the pre-iteration state.- Overrides:
resetin classEvalContext
-
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
