      extended by com.veromodo.tempo.sem.type.TypeGeneric
All Implemented Interfaces:
java.lang.Comparable<Type>

public class TypeGeneric
extends Type

This is a wrapper class which is used to represent the polymorphic types of TIOA (e.g. Seq[T]). A TypeParameter is a type variable within a generic type (T in the Seq[T] example).

Method Detail

is

public boolean is(Type.TypeKind kind)
Description copied from class: Type
Determines if the currently instance is of given TypeKind.

Overrides:
is in class Type
Parameters:
kind - the type of class to compare to
Returns:
true if this is of given TypeKind

select

public Type select(java.lang.String with)
Description copied from class: Type
Returns the type of the given parameter with wrapped in a TypeFunction this ? FT, where FT is the type of the parameter being dereferenced. If the parameter is not found, null it returned.

select returns a function instead of simply returning the type FT because it can more seamlessly integrate with the type checker.

Overrides:
select in class Type
Parameters:
with - the parameter to select
Returns:
a TypeFunction this ? TypeOf(with)

constructedWith

public boolean constructedWith(Type[] at)
Overrides:
constructedWith in class Type

addParam

public void addParam(TypeParameter t)

getBase

public Type getBase()

downCastGeneric

public TypeGeneric downCastGeneric()
Overrides:
downCastGeneric in class Type

resolve

public Type resolve()
Description copied from class: Type
Replaces any bound type parameters with thier bound types. If all parameters are bound, the resulting type is not generic. If no parameters are bounf, the resulting type is this.

Overrides:
resolve in class Type
Returns:
a resolved type

isEqualTo

public boolean isEqualTo(Type t)
required for correct type comparision when doing a scope lookup of resolved types

Overrides:
isEqualTo in class Type

compare

public Type.Order compare(Type t)
Description copied from class: Type
Determines how Type t is realted to this.

Specified by:
compare in class Type
Parameters:
t - to compare to this
Returns:

toString

public java.lang.String toString()
Overrides:
toString in class Type

internalName

public java.lang.String internalName()

getFormals

public java.util.Vector<TypeParameter> getFormals()

visit

public void visit(TypeVisitor v)
Specified by:
visit in class Type

hashCode

public int hashCode()
Overrides:
hashCode in class java.lang.Object
