Class InitialContext
java.lang.Object
org.apache.commons.jxpath.ri.EvalContext
org.apache.commons.jxpath.ri.axes.InitialContext
- All Implemented Interfaces:
Iterator
,ExpressionContext
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.

Method Summary
Modifier and TypeMethodDescriptionReturns the current context node.Returns the first encountered Pointer that matches the current context's criteria.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.Methods inherited from class org.apache.commons.jxpath.ri.EvalContext

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
-
getSingleNodePointer
Description copied from class:EvalContext
Returns the first encountered Pointer that matches the current context's criteria.- Overrides:
getSingleNodePointer
in classEvalContext
- Returns:
- Pointer
-
getValue
Description copied from class:EvalContext
Typically returns the NodeSet by calling getNodeSet(), but will be overridden for contexts that more naturally produce individual values, e.g. VariableContext- Overrides:
getValue
in classEvalContext
- Returns:
- Object
-
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
-
nextSet
Description copied from class:EvalContext
Returns true if there is another sets of objects to interate over. Resets the current position and node.- Overrides:
nextSet
in classEvalContext
- Returns:
- boolean
-
setPosition
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
