Field Detail

EMPTY_ARRAY

static final PsiTypeParameter[] EMPTY_ARRAY

The empty array of PSI type parameters which can be reused to avoid unnecessary allocations.

ARRAY_FACTORY

static final ArrayFactory<PsiTypeParameter> ARRAY_FACTORY

Method Detail

getExtendsList

PsiReferenceList getExtendsList()

Returns the extends list of the type parameter.

Specified by:

getExtendsList in interface PsiClass

Returns:

the extends list. For this particular kind of classes it never returns null.

getOwner

PsiTypeParameterListOwner getOwner()

Returns the element which is parameterized by the type parameter.

Specified by:

getOwner in interface JvmTypeParameter

Returns:

the type parameter owner instance.

See Also:

TypeVariable.getGenericDeclaration()

getIndex

int getIndex()

Returns the position of this type parameter in the type parameter list of the owner element.

Returns:

the type parameter position.

getAnnotations

default PsiAnnotation [] getAnnotations()

Description copied from interface: PsiAnnotationOwner

Returns the list of annotations syntactically contained in the element.

Specified by:

getAnnotations in interface JvmAnnotatedElement

Specified by:

getAnnotations in interface PsiAnnotationOwner

Specified by:

getAnnotations in interface PsiJvmModifiersOwner

Specified by:

getAnnotations in interface PsiModifierListOwner

Returns:

the list of annotations.

hasAnnotation

default boolean hasAnnotation(java.lang.String fqn)

Description copied from interface: PsiAnnotationOwner

Searches the owner for an annotation with the specified fully qualified name and returns true if it is found.

This method is preferable over PsiAnnotationOwner.findAnnotation(java.lang.String) since implementations are free not to instantiate the PsiAnnotation.

Specified by:

hasAnnotation in interface JvmAnnotatedElement

Specified by:

hasAnnotation in interface PsiAnnotationOwner

Specified by:

hasAnnotation in interface PsiJvmModifiersOwner

Specified by:

hasAnnotation in interface PsiModifierListOwner

Parameters:

fqn - the fully qualified name of the annotation to find

Returns:

true is such annotation is found, otherwise false

getBounds

default JvmReferenceType [] getBounds()

Specified by:

getBounds in interface JvmTypeParameter

Returns:

bounds of this type parameter

See Also:

TypeVariable.getBounds(), TypeVariable.getAnnotatedBounds()

accept

default <T> T accept(JvmElementVisitor<T> visitor)

Specified by:

accept in interface JvmClass

Specified by:

accept in interface JvmElement

Specified by:

accept in interface JvmMember

Specified by:

accept in interface JvmTypeParameter
