public AinferTestVisitor(BaseTypeChecker checker)

Method Details

createTypeFactory

protected AinferTestAnnotatedTypeFactory createTypeFactory()

Description copied from class: BaseTypeVisitor

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 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.

Overrides:

createTypeFactory in class BaseTypeVisitor<AinferTestAnnotatedTypeFactory>

Returns:

the appropriate type factory

visitAnnotation

public Void visitAnnotation(AnnotationTree tree,
 Void p)

Description copied from class: BaseTypeVisitor

Ensure that the annotation arguments comply to their declarations. This needs some special casing, as annotation arguments form special trees.

Specified by:

visitAnnotation in interface TreeVisitor<Void,Void>

Overrides:

visitAnnotation in class BaseTypeVisitor<AinferTestAnnotatedTypeFactory>

checkConstructorResult

protected void checkConstructorResult(AnnotatedTypeMirror.AnnotatedExecutableType constructorType,
 ExecutableElement constructorElement)

Description copied from class: BaseTypeVisitor

Issue a warning if the result type of the constructor declaration is not top. If it is a supertype of the class, then a type.invalid.conflicting.annos error will also be issued by BaseTypeVisitor.isValidUse(AnnotatedTypeMirror.AnnotatedDeclaredType,AnnotatedTypeMirror.AnnotatedDeclaredType,Tree).

Overrides:

checkConstructorResult in class BaseTypeVisitor<AinferTestAnnotatedTypeFactory>

Parameters:

constructorType - the AnnotatedExecutableType for the constructor

constructorElement - the element that declares the constructor
