Method Detail

isSubtype

public boolean isSubtype(AnnotationMirror rhs,
                         AnnotationMirror lhs)

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:

rhs - the right-hand side, i.e. the sub qualifier

lhs - the left-hand side, i.e. the super qualifier

Returns:

true iff rhs is a sub qualifier of lhs
