             List<Type> types)

returnType

public Type returnType()

argTypes

public List<Type> argTypes()

hashCode

toString in class Object

checkCompatibility

public void checkCompatibility(Type targetType,
                      String ident,
                      List<Expression> args)

Check whether the list of expression in args is statically compatible with this Signature. This means that args and this.types have the same length, and the type of each expression in args is assignment compatible with the corresponding types in this.types. Also, the targetType must actually contain a non-static method of the appropriate signature and name.

Throws:

IllegalArgumentException - if args is not compatible with this.types.

checkStaticCompatibility

public void checkStaticCompatibility(Type targetType,
                            String ident,
                            List<Expression> args)

Check whether the list of expression in args is statically compatible with this Signature. This means that args and this.types have the same length, and the type of each expression in args is assignment compatible with the corresponding types in this.types. Also, the targetType must actually contain a static method of the appropriate signature and name.

Throws:

IllegalArgumentException - if args is not compatible with this.types.

checkConstructorCompatibility

public void checkConstructorCompatibility(Type targetType,
                                 List<Expression> args)

Check whether the list of expression in args is statically compatible with this Signature. This means that args and this.types have the same length, and the type of each expression in args is assignment compatible with the corresponding types in this.types. Also, the targetType must actually contain a constructor of the appropriate signature and name.

Throws:

IllegalArgumentException - if args is not compatible with this.types.

fromCall

public static Signature fromCall(Type type,
                 String ident,
                 List<Expression> exprs)

fromCallUsingTypes

public static Signature fromCallUsingTypes(Type type,
                           String ident,

fromStaticCall

public static Signature fromStaticCall(Type type,
                       String ident,
                       List<Expression> exprs)

fromStaticCallUsingTypes

public static Signature fromStaticCallUsingTypes(Type type,
                                 String ident,
                                 List<Type> types)

fromConstructorUsingTypes

public static Signature fromConstructorUsingTypes(Type type,
                                  List<Type> types)

fromConstructor

public static Signature fromConstructor(Type type,
                        List<Expression> exprs)
