expression
private org.apache.commons.jxpath.ri.compiler.Expression expression
done
private boolean done
nameTestExpression
private org.apache.commons.jxpath.ri.compiler.Expression nameTestExpression
dynamicPropertyPointer
private org.apache.commons.jxpath.ri.model.beans.PropertyPointer dynamicPropertyPointer
PredicateContext
public PredicateContext(org.apache.commons.jxpath.ri.EvalContext parentContext,
org.apache.commons.jxpath.ri.compiler.Expression expression)
nextNode
public boolean nextNode()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Returns true if there is another object in the current set.
Switches the current position and node to the next object.
setupDynamicPropertyPointer
private boolean setupDynamicPropertyPointer()
- Used for an optimized access to dynamic properties using the
"map[@name = 'name']" syntax
setPosition
public boolean setPosition(int position)
- Description copied from class:
org.apache.commons.jxpath.ri.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.
getCurrentNodePointer
public org.apache.commons.jxpath.ri.model.NodePointer getCurrentNodePointer()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Returns the current context node. Undefined before the beginning
of the iteration.
reset
public void reset()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Sets current position = 0, which is the pre-iteration state.
nextSet
public boolean nextSet()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Returns true if there is another sets of objects to interate over.
Resets the current position and node.
setPositionStandard
private boolean setPositionStandard(int position)
