Method Details

isSubtypeWithElements

protected boolean isSubtypeWithElements(AnnotationMirror subAnno,
 QualifierKind subKind,
 AnnotationMirror superAnno,
 QualifierKind superKind)

Description copied from class: MostlyNoElementQualifierHierarchy

Returns true if subAnno is a subtype of superAnno. Both subAnno and superAnno are annotations with elements. subKind is a sub qualifier kind of superKind.

Specified by:

isSubtypeWithElements in class MostlyNoElementQualifierHierarchy

Parameters:

subAnno - possible subtype annotation; has elements

subKind - the QualifierKind of subAnno

superAnno - possible super annotation; has elements

superKind - the QualifierKind of superAnno

Returns:

true if subAnno is a subtype of superAnno

leastUpperBoundWithElements

protected AnnotationMirror leastUpperBoundWithElements(AnnotationMirror a1,
 QualifierKind qualifierKind1,
 AnnotationMirror a2,
 QualifierKind qualifierKind2,
 QualifierKind lubKind)

Description copied from class: MostlyNoElementQualifierHierarchy

Returns the least upper bound of a1 and a2 in cases where the lub of qualifierKind1 and qualifierKind2 is a qualifier kind that has elements. If the lub of qualifierKind1 and qualifierKind2 does not have elements, then MostlyNoElementQualifierHierarchy.leastUpperBound(AnnotationMirror, AnnotationMirror) returns the correct AnnotationMirror without calling this method.

Specified by:

leastUpperBoundWithElements in class MostlyNoElementQualifierHierarchy

Parameters:

a1 - first annotation

qualifierKind1 - QualifierKind for a1

a2 - second annotation

qualifierKind2 - QualifierKind for a2

lubKind - the kind of the lub of qualifierKind1 and qualifierKind2

Returns:

the least upper bound of a1 and a2

greatestLowerBoundWithElements

protected AnnotationMirror greatestLowerBoundWithElements(AnnotationMirror a1,
 QualifierKind qualifierKind1,
 AnnotationMirror a2,
 QualifierKind qualifierKind2,
 QualifierKind glbKind)

Description copied from class: MostlyNoElementQualifierHierarchy

Returns the greatest lower bound of a1 and a2 in cases where the glb of qualifierKind1 and qualifierKind2 is a qualifier kind that has elements. If the glb of qualifierKind1 and qualifierKind2 does not have elements, then MostlyNoElementQualifierHierarchy.greatestLowerBound(AnnotationMirror, AnnotationMirror) returns the correct AnnotationMirror without calling this method.

Specified by:

greatestLowerBoundWithElements in class MostlyNoElementQualifierHierarchy

Parameters:

a1 - first annotation

qualifierKind1 - QualifierKind for a1

a2 - second annotation

qualifierKind2 - QualifierKind for a2

Returns:

the greatest lower bound between a1 and a2
