invoke

public java.lang.Object invoke(EvaluationContext ctx,
                               java.lang.Object outputs,
                               java.lang.Object inputExpressionList,
                               java.util.List<?> inputValuesList,
                               java.lang.Object outputValues,
                               java.util.List<java.util.List> ruleList,
                               java.lang.String hitPolicy,
                               java.lang.Object defaultOutputValue)

Parameters:

inputExpressionList - a list of the N>=0 input expressions in display order

inputValuesList - * a list of N input values, corresponding to the input expressions. Each list element is a unary tests literal (see below).

outputs - * a name (a string matching grammar rule 27) or a list of M>0 names

outputValues - * if outputs is a list, then output values is a list of lists of values, one list per output; else output values is a list of values for the one output. Each value is a string.

ruleList - a list of R>0 rules. A rule is a list of N input entries followed by M output entries. An input entry is a unary tests literal. An output entry is an expression represented as a string.

hitPolicy - * one of: "U", "A", “P”, “F”, "R", "O", "C", "C+", "C#", "C<", “C>” (default is "U")

defaultOutputValue - * if outputs is a list, then default output value is a context with entries composed of outputs and output values; else default output value is one of the output values.

                                                                          java.util.List<java.util.List<java.lang.Object>> values)
