Constructor Summary

RootContext(org.apache.commons.jxpath.ri.JXPathContextReferenceImpl jxpathContext, org.apache.commons.jxpath.ri.model.NodePointer pointer)


Method Summary

org.apache.commons.jxpath.ri.EvalContext getAbsoluteRootContext()


org.apache.commons.jxpath.ri.EvalContext getConstantContext(java.lang.Object constant)


org.apache.commons.jxpath.ri.model.NodePointer getCurrentNodePointer()
          Returns the current context node.

int getCurrentPosition()


org.apache.commons.jxpath.Function getFunction(org.apache.commons.jxpath.ri.QName functionName, java.lang.Object[] parameters)


org.apache.commons.jxpath.JXPathContext getJXPathContext()
          Get the JXPathContext in which this function is being evaluated.

java.lang.Object getRegisteredValue(int id)


RootContext getRootContext()
          Returns the root context of the path, which provides easy access to variables and functions.

java.lang.Object getValue()
          Typically returns the NodeSet by calling getNodeSet(), but will be overridden for contexts that more naturally produce individual values, e.g.

org.apache.commons.jxpath.ri.EvalContext getVariableContext(org.apache.commons.jxpath.ri.QName variableName)


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.

int setRegisteredValue(java.lang.Object value)


java.lang.String toString()
          Convert this Object to a human-readable String.
