Method Detail

main

public static void main(java.lang.String[] args)

importClasses

public void importClasses(java.util.ResourceBundle classmap)

Configures a set of classnames such that the parser can refer to them without their full package names. This is the functional equivalent of a set of import statements. The keys of this resource bundle must be Stringscontaining the name of the class within its package, and the values may be either Strings containing the fully qualified classnames or the corresponding Class objects.

Classes in the java.lang package are imported by default, and they will not be looked up in the resource bundle passed to this method.

checkReservedNames

protected FunctorRef checkReservedNames(java.lang.String name)
                                 throws ParseException

Allows for functor names to be added to the grammar.

Throws:

ParseException

parseGenerator

public Generator parseGenerator(java.lang.String str)
                         throws ParseException

Parses the string to create a Generator.

Throws:

ParseException

parseGenerator

public Generator parseGenerator()
                         throws ParseException

Parses the contents of the current input to create a Generator

Throws:

ParseException

parseUnary

public UnaryFunctor parseUnary(java.lang.String str,
                               java.lang.Class argType)
                        throws ParseException

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

Throws:

parseUnary

public UnaryFunctor parseUnary(java.lang.Class argType)
                        throws ParseException

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

Throws:

ParseException

parseBinary

public BinaryFunctor parseBinary(java.lang.String str,
                                 java.lang.Class arg1Type,
                                 java.lang.Class arg2Type)
                          throws ParseException

Parses the string to create a BinaryFunctor that takes arguments of the given types.

Throws:

ParseException

parseBinary

public BinaryFunctor parseBinary(java.lang.Class arg1Type,
                                 java.lang.Class arg2Type)
                          throws ParseException

Parses the current input to create a BinaryFunctor that takes arguments of the given types.

Throws:

ParseException

getReturnType

public 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.
