A checker for type qualifier systems that only checks subtyping relationships.

The annotation(s) are specified on the command line, using an annotation processor argument:

Constructor Detail

BasicChecker

public BasicChecker()
Method Detail

createFactory

public AnnotatedTypeFactory createFactory(CompilationUnitTree root)
Description copied from class: BaseTypeChecker
Constructs an instance of the appropriate type factory for the implemented type system. The default implementation uses the checker naming convention to create the appropriate type factory. If no factory is found, it returns BasicAnnotatedTypeFactory. 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.

Overrides:
createFactory in class BaseTypeChecker
Parameters:
root - the currently visited compilation unit
Returns:
the appropriate type factory

createSupportedTypeQualifiers

protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers()
Description copied from class: BaseTypeChecker
If the checker class is annotated with TypeQualifiers, return an immutable set with the same set of classes as the annotation. If the class is not so annotated, return an empty set. Subclasses may override this method to return an immutable set of their supported type qualifiers.

Overrides:
createSupportedTypeQualifiers in class BaseTypeChecker
Returns:
the type qualifiers supported this processor, or an empty set if none
