Constructor Detail

CompoundTypeReference

public CompoundTypeReference(ITypeReferenceOwner owner,
                             boolean synonym)

Method Detail

getKind

public int getKind()

Subclasses must override this method.

Overrides:

getKind in class LightweightTypeReference

toTypeReference

public org.eclipse.xtext.common.types.JvmTypeReference toTypeReference()

Specified by:

toTypeReference in class LightweightTypeReference

isVisible

public boolean isVisible(IVisibilityHelper visibilityHelper)

Description copied from class: LightweightTypeReference

Returns true if this type is fully visible according to the given visibilityHelper. All components and bounds are taken into account, e.g. arrays use their component type and generified types check their type arguments, too.

Specified by:

isVisible in class LightweightTypeReference

toJavaCompliantTypeReference

public org.eclipse.xtext.common.types.JvmTypeReference toJavaCompliantTypeReference(IVisibilityHelper visibilityHelper)

Converts this type reference to a JvmTypeReference that can be used in Java source code. If this is a multi-type rather than a synonym, the Java compliant type reference is determined from the common super type of all participating, non-interface types. If there is no such type or this is a synonym, all the component types are used to compute the common super type and use that one as the type.

Specified by:

toJavaCompliantTypeReference in class LightweightTypeReference

getTypeArguments

public java.util.List<LightweightTypeReference> getTypeArguments()

Description copied from class: LightweightTypeReference

Returns the type arguments of this reference if it has any. The type argument of List<String> is String. is also the type argument of a wildcard reference with upper bound ? extends List<String>. Raw types don't carry type arguments. Wildcards with more than one upper bound don't carry type arguments.

Overrides:

getTypeArguments in class LightweightTypeReference

isRawType

public boolean isRawType()

Description copied from class: LightweightTypeReference

Returns true is this type points to a raw type. That is, it points to a parameterized type but does not define type arguments or it points to an external type parameter that has a raw type constraint. Type parameters that are declared by the current owner are not considered to be raw types. A type is also a raw type if it inherits from a raw type.

Overrides:

isRawType in class LightweightTypeReference

isArray

public boolean isArray()

Overrides:

isArray in class LightweightTypeReference

getComponentType

public LightweightTypeReference getComponentType()

Description copied from class: LightweightTypeReference

Returns the component type of the current array type. Does not attempt to convert this reference from iterable to array, first.

Overrides:

getComponentType in class LightweightTypeReference

Returns:

the compoent type of the current array or null.

getSuperType

public LightweightTypeReference getSuperType(org.eclipse.xtext.common.types.JvmType rawType)

Description copied from class: LightweightTypeReference

Returns the resolved super type for the given raw type or null if the raw type is not a valid super type of this type.

Overrides:

getSuperType in class LightweightTypeReference

Parameters:

Returns:

the resolved super type.

getSuperType

public LightweightTypeReference getSuperType(java.lang.Class<?> rawType)

Description copied from class: LightweightTypeReference

Returns the resolved super type for the given raw type or null if the raw type is not a valid super type of this type.

Overrides:

getSuperType in class LightweightTypeReference

Parameters:

rawType - the raw type that should be resolved.

Returns:

the resolved super type.

isType

public boolean isType(java.lang.Class<?> clazz)

Description copied from class: LightweightTypeReference

Returns true if this type reference represents an type with the given raw type clazz. Returns false if this is not exactly the given type, but a sub type, a super type or a completely unrelated type.

Specified by:

isType in class LightweightTypeReference

doCopyInto

protected LightweightTypeReference doCopyInto(ITypeReferenceOwner owner)

Specified by:

doCopyInto in class LightweightTypeReference
