                                   java.lang.Class<T1> argType)
                              throws ParseException

Parses the string to create a UnaryFunctor that takes an argument of the given type.

Throws:

ParseException

parseBinary

<T1,T2> BinaryFunctor<T1,T2,?> parseBinary(java.lang.String str,
                                           java.lang.Class<T1> arg1Type,

Throws:

ParseException

getReturnType

java.lang.Class<?> getReturnType()

Returns the type of object returned by the last functor parsed.

Throws:

java.lang.IllegalStateException - if the parser has not been used or if parsing the last functor resulted in an exception being thrown.
