Class InitialContext
- ExpressionContext, Iterator
public class InitialContext
A single-set EvalContext that provides access to the current node of
the parent context and nothing else. It does not pass the iteration
on to the parent context.

NodePointer | getCurrentNodePointer() - Returns the current context node.
|
Pointer | getSingleNodePointer() - Returns the first encountered Pointer that matches the current
context's criteria.
|
Object | getValue() - Typically returns the NodeSet by calling getNodeSet(),
but will be overridden for contexts that more naturally produce
individual values, e.g.
|
boolean | nextNode() - Returns true if there is another object in the current set.
|
boolean | nextSet() - Returns true if there is another sets of objects to interate over.
|
boolean | setPosition(int position) - Moves the current position to the specified index.

InitialContext
public InitialContext(EvalContext parentContext)
getValue
public Object getValue()
Typically returns the NodeSet by calling getNodeSet(),
but will be overridden for contexts that more naturally produce
individual values, e.g. VariableContext
- getValue in interface EvalContext
nextNode
public boolean nextNode()
Returns true if there is another object in the current set.
Switches the current position and node to the next object.
- nextNode in interface EvalContext
nextSet
public boolean nextSet()
Returns true if there is another sets of objects to interate over.
Resets the current position and node.
- nextSet in interface EvalContext
setPosition
public boolean setPosition(int position)
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.
