protected void |
commonAssignmentCheck(AnnotatedTypeMirror varType,
ExpressionTree valueExp,
@CompilerMessageKey String errorKey)
ValueVisitor overrides this method so that it does not have to check variables annotated with
the
IntRangeFromPositive annotation. |
protected ValueAnnotatedTypeFactory |
createTypeFactory()
Constructs an instance of the appropriate type factory for the implemented type system.
|
Void |
visitAnnotation(AnnotationTree node,
Void p)
Warns about malformed constant-value annotations.

annotation. This annotation is only introduced by the Index
Checker's Positive
annotation. It is safe to
defer checking of these values to the Index Checker because this is only introduced for
explicitly-written Positive
annotations,
which must be checked by the Lower Bound Checker.commonAssignmentCheck

BaseTypeVisitor
The default implementation uses the checker naming convention to create the appropriate
type factory. If no factory is found, it returns BaseAnnotatedTypeFactory
. It
reflectively invokes the constructor that accepts this checker and compilation unit tree (in
that order) as arguments.
Subclasses have to override this method to create the appropriate visitor if they do not follow the checker naming convention.

in class BaseTypeVisitor<ValueAnnotatedTypeFactory>
public Void visitAnnotation(AnnotationTree node, Void p)
Issues an error if any @IntRange annotation has its 'from' value greater than 'to' value.
Issues a warning if any constant-value annotation has > MAX_VALUES arguments.
