public boolean isValidUse(AnnotatedTypeMirror.AnnotatedDeclaredType declarationType, AnnotatedTypeMirror.AnnotatedDeclaredType useType)
BaseTypeVisitor
The check is shallow, as it does not descend into generic or array
types (i.e. only performing the validity check on the raw type or
outermost array dimension). BaseTypeVisitor.validateTypeOf(Tree)
would call this for each type argument or array dimension separately.
For instance, in the IGJ type system, a @Mutable
is an invalid
qualifier for String
, as String
is declared as
@Immutable String
.
In most cases, useType
simply needs to be a subtype of
declarationType
, but there are exceptions. In IGJ, a variable may be
declared @ReadOnly String
, even though String
is
@Immutable String
; ReadOnly
is not a subtype of
Immutable
.
isValidUse
in class BaseTypeVisitor<FenumChecker>
declarationType
- the type of the class (TypeElement)useType
- the use of the class (instance type)
