public class BasicAnnotatedTypeFactory<Checker extends BaseTypeChecker>
extends AnnotatedTypeFactory

A factory that extends AnnotatedTypeFactory to optionally use flow-sensitive qualifier inference, qualifier polymorphism, implicit annotations via ImplicitFor, and user-specified defaults via DefaultQualifier

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

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
