nodeSet

private org.apache.commons.jxpath.NodeSet nodeSet

Constructor Detail

NodeSetContext

public NodeSetContext(org.apache.commons.jxpath.ri.EvalContext parentContext,
                      org.apache.commons.jxpath.NodeSet nodeSet)

Method Detail

getNodeSet

public org.apache.commons.jxpath.NodeSet getNodeSet()

Description copied from class: org.apache.commons.jxpath.ri.EvalContext

Returns the list of all Pointers in this context for all positions of the parent contexts. If there was an ongoing iteration over this context, the method should not be called.

---

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.

---

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.

---

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.

---

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.
