Class CompiledAxisMappingFunction

  • All Implemented Interfaces:

    public abstract class CompiledAxisMappingFunction
    extends java.lang.Object
    implements MappingFunction
    Abstract MappingFunction class that must be passed to a MappingIterator. This implementation of MappingFunction acts as a superclass for generated bytecode classes used to implement path expressions where the RHS is an AxisExpression: these can be evaluated without creating a new context or FocusIterator.
