  • All Implemented Interfaces:
    JexlMethod
    Enclosing class:

                                  java.lang.Object... params)
                           throws JexlException.TryFailed
        Description copied from interface: JexlMethod
        Attempts to reuse this JexlMethod, checking that it is compatible with the actual set of arguments. Related to isCacheable since this method is often used with cached JexlMethod instances.
        Specified by:
        tryInvoke in interface JexlMethod
        Overrides:
        tryInvoke in class Operator.CompareMethod
        Parameters:
        name - the method name
        arithmetic - the object to invoke the method upon
        params - the method arguments
        Returns:
        the result of the method invocation that should be checked by tryFailed to determine if it succeeded or failed.
        Throws:
        JexlException.TryFailed - if the underlying method was invoked but threw an exception (InvocationTargetException)
