Method Detail

finish

protected void finish(QualifierHierarchy qualHierarchy,
                      Map<AnnotationMirror,Set<AnnotationMirror>> fullMap,
                      Map<AnnotationMirror,AnnotationMirror> polyQualifiers,

                      Object... args)

Description copied from class: MultiGraphQualifierHierarchy

Method to finalize the qualifier hierarchy before it becomes unmodifiable. The parameters pass all fields and allow modification.

Overrides:

finish in class MultiGraphQualifierHierarchy

getTopAnnotations

public Set<? extends AnnotationMirror> getTopAnnotations()

Returns the top qualifier for this hierarchy.

The top qualifier is inferred from the hierarchy, as being the only one without any super qualifiers

Overrides:

getTopAnnotations in class MultiGraphQualifierHierarchy

Returns:

the top (ultimate super) type qualifiers in the type system

getBottomAnnotations

public Set<? extends AnnotationMirror> getBottomAnnotations()

Overrides:

getBottomAnnotations in class MultiGraphQualifierHierarchy

Returns:

the bottom type qualifier in the hierarchy

isSubtype

public boolean isSubtype(Collection<? extends AnnotationMirror> rhs,
                         Collection<? extends AnnotationMirror> lhs)

Description copied from class: QualifierHierarchy

Tests whether there is any annotation in lhs that is a super qualifier of some annotation in rhs. lhs and rhs contain only the annotations, not the Java type.

Overrides:

isSubtype in class MultiGraphQualifierHierarchy

Returns:

true iff an annotation in lhs is a super of one in rhs
