Method Details
-
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
-
getCurrentPosition
public int getCurrentPosition()Description copied from class:EvalContext
Get the current position.- Overrides:
getCurrentPosition
in classEvalContext
- Returns:
- int position.
-
getDocumentOrder
public int getDocumentOrder()Description copied from class:EvalContext
Determines the document order for this context.- Overrides:
getDocumentOrder
in classEvalContext
- Returns:
- 1 ascending order, -1 descending order, 0 - does not require ordering
-
reset
public void reset()Description copied from class:EvalContext
Sets current position = 0, which is the pre-iteration state.- Overrides:
reset
in classEvalContext
-
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
-
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
