getDeclaredTypeParameters

public java.util.List<org.eclipse.xtext.common.types.JvmTypeParameter> getDeclaredTypeParameters()

Returns:

the empty list

toPlainTypeReference

public LightweightTypeReference toPlainTypeReference(org.eclipse.xtext.common.types.JvmType type)

Description copied from interface: ITypeReferenceOwner

Creates a new type reference that points to the given type. If the type is a JvmArrayType, an ArrayTypeReference is produced. The produced LightweightTypeReference does not have any type arguments. It is similar to a raw type reference except for cases where the type points to a JvmTypeParameter or an array of type parameters. In those cases, the result is different form toPlainTypeReference(JvmType). getRawTypeReference().

Specified by:

toPlainTypeReference in interface ITypeReferenceOwner

Parameters:

type - the type. May not be null.

toLightweightTypeReference

public LightweightTypeReference toLightweightTypeReference(org.eclipse.xtext.common.types.JvmType type)

Description copied from interface: ITypeReferenceOwner

Creates a new type reference that points to the given type. If the type is a JvmArrayType, an ArrayTypeReference is produced. The produced LightweightTypeReference does have type arguments if the given type is generic or an array of a generic type. The type arguments point to the original type parameters. Useful for later substitution of all type parameters.

Specified by:

toLightweightTypeReference in interface ITypeReferenceOwner

Parameters:

type - the raw type. May not be null.

toLightweightTypeReference

public LightweightTypeReference toLightweightTypeReference(org.eclipse.xtext.common.types.JvmTypeReference type)

Description copied from interface: ITypeReferenceOwner

Transforms the given EMF based type reference to its equivalent in the LightweightTypeReference hierarchy.

Specified by:

toLightweightTypeReference in interface ITypeReferenceOwner

Parameters:

type - the type to convert. May not be null.

newCompoundTypeReference

public CompoundTypeReference newCompoundTypeReference(boolean synonym)

Description copied from interface: ITypeReferenceOwner

Creates a new CompoundTypeReference that is either a synonym or a multi type reference.

Specified by:

newCompoundTypeReference in interface ITypeReferenceOwner

Parameters:

synonym - whether it should be a synonym type reference.

newWildcardTypeReference

public WildcardTypeReference newWildcardTypeReference()

Description copied from interface: ITypeReferenceOwner

Creates a new WildcardTypeReference without any upper or lower bounds. Usually clients need to add those to make it a valid type reference.

Specified by:

newWildcardTypeReference in interface ITypeReferenceOwner

newArrayTypeReference

public ArrayTypeReference newArrayTypeReference(LightweightTypeReference componentTypeReference)

Description copied from interface: ITypeReferenceOwner

Creates a new ArrayTypeReference with the given component type.

Specified by:

newArrayTypeReference in interface ITypeReferenceOwner

newFunctionTypeReference

public FunctionTypeReference newFunctionTypeReference(org.eclipse.xtext.common.types.JvmType type)

Description copied from interface: ITypeReferenceOwner

Creates a new FunctionTypeReference that is backed by the given type. Constraints apply as in ITypeReferenceOwner.newParameterizedTypeReference(JvmType). Clients are responsible to pass a valid SAM type to ITypeReferenceOwner.newFunctionTypeReference(JvmType).

Specified by:

newFunctionTypeReference in interface ITypeReferenceOwner

Parameters:

type - the raw function type.

newFunctionTypeReference

public InnerFunctionTypeReference newFunctionTypeReference(LightweightTypeReference outer,
                                                           org.eclipse.xtext.common.types.JvmType type)

Description copied from interface: ITypeReferenceOwner

Create a new InnerFunctionTypeReference that is backed by the given type and has to defined outer type. Constraints apply as in ITypeReferenceOwner.newFunctionTypeReference(JvmType) and ITypeReferenceOwner.newParameterizedTypeReference(LightweightTypeReference, JvmType).

Specified by:

newFunctionTypeReference in interface ITypeReferenceOwner

Parameters:

outer - the outer type reference.

type - the raw type for the newly produced ParameterizedTypeReference

newParameterizedTypeReference

public ParameterizedTypeReference newParameterizedTypeReference(org.eclipse.xtext.common.types.JvmType type)

Description copied from interface: ITypeReferenceOwner

Creates a new ParameterizedTypeReference from the given type. The type may either be a JvmTypeParameter, JvmPrimitiveType, JvmDeclaredType or JvmVoid. Other types are considered invalid and will cause an IllegalArgumentException to be thrown. If the type is a non-static nested type, the produced type reference will be an InnerTypeReference. The produced type reference does not have any type arguments. If the given type is generic, the returned type reference is a raw type.

Specified by:

newParameterizedTypeReference in interface ITypeReferenceOwner

Parameters:

type - the raw type for the newly produced ParameterizedTypeReference

newParameterizedTypeReference

public InnerTypeReference newParameterizedTypeReference(LightweightTypeReference outer,
                                                        org.eclipse.xtext.common.types.JvmType type)

Description copied from interface: ITypeReferenceOwner

Creates a new InnerTypeReference. Constraints apply as with ITypeReferenceOwner.newParameterizedTypeReference(JvmType). If type does not represent a non-static inner class, an exception is thrown. This method produces references of the form Outer<OuterParams>.Type.

Specified by:

newParameterizedTypeReference in interface ITypeReferenceOwner

Parameters:

outer - the outer type reference.

type - the raw type for the newly produced ParameterizedTypeReference
