Method Detail

getTarget

public static Type getTarget(TypeReference me)

Returns the type referenced by this TypeReference considering all concrete subclasses of TypeReference used by the Java meta-model.

Parameters:

me - the type reference to obtain the type from.

Returns:

the referenced type

setTarget

public static void setTarget(TypeReference me,
                             Classifier type)

Sets the type targeted by this type reference.

Parameters:

me - the type reference whose type is set.

type - the new type to set as target.

getBoundTarget

public static Type getBoundTarget(TypeReference me,
                                  Reference reference)

Returns the type referenced by this TypeReference considering all concrete subclasses of TypeReference used by the Java meta-model. If type parameters are bound in the given reference, the bound type will be returned instead of the parameter.

Parameters:

me - the type reference to obtain the type for.

reference - the context of the type reference.

Returns:

the referenced type.

getBoundTargetReference

public static TypeReference getBoundTargetReference(TypeReference me,
                                                    Reference reference)

getTypeReferenceOfTypeArgument

public static TypeReference getTypeReferenceOfTypeArgument(TypeReference ref,
                                                           int index)

getTypeReferenceOfTypeArgument

public static TypeReference getTypeReferenceOfTypeArgument(TypeArgument arg)

Returns the type reference for a type argument. If the type argument is a QualifiedTypeArgument, the returned type reference is the qualified type. If the type argument is a SuperTypeArgument, the lower bound is returned. If the type argument is an ExtendsTypeArgument, the upper bound is returned. If the type argument is an UnknownTypeArgument, null is returned.

Parameters:

arg - the type argument.

Returns:

the type reference for the type argument or null.

convertToTypeReference

public static TypeReference convertToTypeReference(EObject obj)

clone

public static TypeReference clone(TypeReference me)

getPureClassifierReference

public static ClassifierReference getPureClassifierReference(TypeReference me)

Extracts the (possibly nested) ClassifierReference (if any) from a TypeReference.

Parameters:

me - the TypeReference to extract the ClassifierReference from.

Returns:

the extracted ClassifierReference.
