java.lang.Object
  net.sf.saxon.expr.UserFunctionCall.FunctionCallPackage

Enclosing class:

UserFunctionCall

public static class UserFunctionCall.FunctionCallPackage

extends java.lang.Object

Inner class used to wrap up the set of actual arguments to a tail-recursive call of the containing function. This argument package is passed back to the calling FunctionInstr in place of a function result; the FunctionInstr then loops to re-invoke the function with these arguments, avoiding the creation of an additional stack frame.
