Constructor Detail

BasicAnnotatedTypeFactory

public BasicAnnotatedTypeFactory(Checker checker,
                                 CompilationUnitTree root,
                                 boolean useFlow)

Creates a type factory for checking the given compilation unit with respect to the given annotation.

Parameters:

checker - the checker to which this type factory belongs

root - the compilation unit to scan

useFlow - whether flow analysis should be performed

BasicAnnotatedTypeFactory

public BasicAnnotatedTypeFactory(Checker checker,
                                 CompilationUnitTree root)

Creates a type factory for checking the given compilation unit with respect to the given annotation.

Parameters:

checker - the checker to which this type factory belongs

root - the compilation unit to scan

Method Detail

createTreeAnnotator

protected TreeAnnotator createTreeAnnotator(Checker checker)

Returns a TreeAnnotator that adds annotations to a type based on the contents of a tree. Subclasses may override this method to specify more appriopriate TreeAnnotator

Returns:

a tree annotator

createTypeAnnotator

protected TypeAnnotator createTypeAnnotator(Checker checker)

Returns a TypeAnnotator that adds annotations to a type based on the content of the type itself.

Returns:

a type annotator

createFlow

protected Flow createFlow(Checker checker,
                          CompilationUnitTree root,
                          Set<AnnotationMirror> flowQuals)

Returns a Flow instance that performs flow sensitive analysis to infer qualifiers on unqualified types.

Parameters:

checker - the checker

root - the compilation unit associated with this factory

flowQuals - the qualifiers to infer

Returns:

the flow analysis class

postDirectSuperTypes

protected void postDirectSuperTypes(AnnotatedTypeMirror type,
                                    List<? extends AnnotatedTypeMirror> supertypes)

Description copied from class: AnnotatedTypeFactory

A callback method for the AnnotatedTypeFactory subtypes to customize directSuperTypes(). Overriding methods should merely change the annotations on the supertypes, without adding or removing new types The default provided implementation adds type annotations to supertypes. This allows the type and its supertypes to have the qualifiers, e.g. the supertypes of an Immutable type are also Immutable.

Overrides:

postDirectSuperTypes in class AnnotatedTypeFactory

Parameters:

type - the type whose supertypes are desired

supertypes - the supertypes as specified by the base AnnotatedTypeFactory

annotateImplicit

protected void annotateImplicit(Tree tree,
                                AnnotatedTypeMirror type)

Description copied from class: AnnotatedTypeFactory

Adds implicit annotations to a type obtained from a Tree. By default, this method does nothing. Subclasses should use this method to implement implicit annotations specific to their type systems.

Overrides:

annotateImplicit in class AnnotatedTypeFactory

Parameters:

tree - an AST node

type - the type obtained from tree

annotateImplicit

protected void annotateImplicit(Element elt,
                                AnnotatedTypeMirror type)

Description copied from class: AnnotatedTypeFactory

Adds implicit annotations to a type obtained from a Element. By default, this method does nothing. Subclasses should use this method to implement implicit annotations specific to their type systems.

Overrides:

annotateImplicit in class AnnotatedTypeFactory

Parameters:

elt - an element

type - the type obtained from elt

methodFromUse

public AnnotatedTypeMirror.AnnotatedExecutableType methodFromUse(MethodInvocationTree tree)

Description copied from class: AnnotatedTypeFactory

Determines the type of the invoked method based on the passed method invocation tree. The returned method type has all type variables resolved, whether based on receiver type, passed type parameters if any, and method invocation parameter. Subclasses may override this method to customize inference of types or qualifiers based on method invocation parameters. As an implementation detail, this method depends on AnnotatedTypes.asMemberOf(AnnotatedTypeMirror, Element), and customization based on receiver type should be in accordance to its specification.

Overrides:

methodFromUse in class AnnotatedTypeFactory

Parameters:

tree - the method invocation tree

Returns:

the method type being invoked with tree

createFlowQualifiers

protected Set<AnnotationMirror> createFlowQualifiers(Checker checker)

Returns the set of annotations to be inferred in flow analysis
