DescendantContext(EvalContext parentContext,

Create a new DescendantContext.
|
Modifier and Type | Method and Description |
---|---|
NodePointer |
getCurrentNodePointer()
Returns the current context node.
|
boolean |
isChildOrderingRequired()
Even if this context has the natural ordering and therefore does
not require collecting and sorting all nodes prior to returning them,
such operation may be required for any child context.
|
private boolean |
isRecursive()
Checks if we are reentering a bean we have already seen and if so
returns true to prevent infinite recursion.
|
boolean |
nextNode()
Returns true if there is another object in the current set.
|
void |
reset()
Sets current position = 0, which is the pre-iteration state.
|
boolean |
setPosition(int position)
Moves the current position to the specified index.
