Class FunctionSafeJep


  • public class FunctionSafeJep
    extends JEP
    Extension to the JEP parser that provides better error handling for unknown functions. The normal error message when JEP encounters an unknown function is: Syntax Error (implicit multiplication not enabled). This is not very informative so this class improves the error handling by giving a message: Unknown function foo() instead.
