Method Detail

findBottoms

protected java.util.Set<javax.lang.model.element.AnnotationMirror> findBottoms(java.util.Map<javax.lang.model.element.AnnotationMirror,java.util.Set<javax.lang.model.element.AnnotationMirror>> supertypes)

Description copied from class: MultiGraphQualifierHierarchy

Infer the bottoms of the subtype hierarchy. Simple finds the qualifiers that are not supertypes of other qualifiers.

Overrides:

findBottoms in class MultiGraphQualifierHierarchy

findTops

protected java.util.Set<javax.lang.model.element.AnnotationMirror> findTops(java.util.Map<javax.lang.model.element.AnnotationMirror,java.util.Set<javax.lang.model.element.AnnotationMirror>> supertypes)

Description copied from class: MultiGraphQualifierHierarchy

Infer the tops of the subtype hierarchy. Simply finds the qualifiers that have no supertypes.

Overrides:

findTops in class MultiGraphQualifierHierarchy

isSubtype

public boolean isSubtype(javax.lang.model.element.AnnotationMirror subAnno,
                         javax.lang.model.element.AnnotationMirror superAnno)

Description copied from class: MultiGraphQualifierHierarchy

Tests whether rhs is equal to or a sub-qualifier of lhs, according to the type qualifier hierarchy. This checks only the qualifiers, not the Java type.

Most qualifiers have no value fields. However, two annotations with values are subtype of each other only if they have the same values. i.e. I(m) is a subtype of I(n) iff m = n.

When client specifies an annotation, a1, to be a subtype of annotation with values, a2, then a1 is a subtype of all instances of a2 regardless of a2 values.

Overrides:

isSubtype in class MultiGraphQualifierHierarchy

Parameters:

subAnno - the sub qualifier

superAnno - the super qualifier

Returns:

true iff rhs is a sub qualifier of lhs
