                                       XPathContext context)

      Description copied from class: `ScalarSystemFunction`
      Abstract method that must be supplied in subclasses to perform the evaluation
      Specified by:
        `evaluate` in class `ScalarSystemFunction`

      Overrides:
        `getCompilerName` in class `SystemFunction`
      Returns:
        the name of a bytecode generation class, or null if there is no bytecode support for this function
