    • makeFunctionCall

      public Expression makeFunctionCall(Expression[] arguments)
      Description copied from class: SystemFunction
      Make an expression that either calls this function, or that is equivalent to a call on this function
      Overrides:
      makeFunctionCall in class SystemFunction
      Parameters:
      arguments - the supplied arguments to the function call
      Returns:
      either a function call on this function, or an expression that delivers the same result
    • call

      public Sequence call(XPathContext context, Sequence[] arguments) throws XPathException
      Evaluate the expression as a general function call
      Parameters:
      context - the dynamic evaluation context
      arguments - the values of the arguments, supplied as SequenceIterators
      Returns:
      the result of the evaluation, in the form of a SequenceIterator
      Throws:
      XPathException - if a dynamic error occurs during the evaluation of the expression
    • getStreamerName

      public String getStreamerName()
      Description copied from class: SystemFunction
      Get a name that identifies the class that can be used to evaluate this function in streaming mode, that is, supplying one item or event at a time as it is delivered by the parser. Special streaming support is generally available in Saxon-EE for all system functions that take a sequence as their argument.
      Overrides:
      getStreamerName in class SystemFunction
      Returns:
      a name that identifies a class that supports streamed evaluation of this system function, or null if no such class is available. The mapping of names to classes is defined in the Saxon-EE class StreamerMap. In non-streaming Saxon editions (HE and PE) the method always returns null.
