STANDARD_CLIMB_DEFAULTS_TOP

public static final TypeUseLocation[] STANDARD_CLIMB_DEFAULTS_TOP

CLIMB locations whose standard default is top for a given type system.

STANDARD_CLIMB_DEFAULTS_BOTTOM

public static final TypeUseLocation[] STANDARD_CLIMB_DEFAULTS_BOTTOM

CLIMB locations whose standard default is bottom for a given type system.

STANDARD_UNCHECKED_DEFAULTS_TOP

public static final TypeUseLocation[] STANDARD_UNCHECKED_DEFAULTS_TOP

Constructor Detail

QualifierDefaults

public QualifierDefaults(Elements elements,
                         AnnotatedTypeFactory atypeFactory)

Parameters:

elements - interface to Element data in the current processing environment

atypeFactory - an annotation factory, used to get annotations by name

Method Detail

validLocationsForUncheckedCodeDefaults

public static TypeUseLocation[] validLocationsForUncheckedCodeDefaults()

Returns an array of locations that are valid for the unchecked value defaults. These are simply by syntax, since an entire file is typechecked, it is not possible for local variables to be unchecked.

toString

public String toString()

Overrides:

toString in class Object

hasDefaultsForCheckedCode

public boolean hasDefaultsForCheckedCode()

Check that a default with TypeUseLocation OTHERWISE or ALL is specified.

Returns:

whether we found a Default with location OTHERWISE or ALL

addUncheckedStandardDefaults

public void addUncheckedStandardDefaults()

Add standard unchecked defaults that do not conflict with previously added defaults.

addClimbStandardDefaults

public void addClimbStandardDefaults()

Add standard CLIMB defaults that do not conflict with previously added defaults.

addCheckedCodeDefault

public void addCheckedCodeDefault(AnnotationMirror absoluteDefaultAnno,
                                  TypeUseLocation location)

Sets the default annotations. A programmer may override this by writing the @DefaultQualifier annotation on an element.

addUncheckedCodeDefault

public void addUncheckedCodeDefault(AnnotationMirror uncheckedDefaultAnno,
                                    TypeUseLocation location)

Sets the default annotation for unchecked elements.

addUncheckedCodeDefaults

public void addUncheckedCodeDefaults(AnnotationMirror absoluteDefaultAnno,
                                     TypeUseLocation[] locations)

Sets the default annotation for unchecked elements, with specific locations.

addCheckedCodeDefaults

public void addCheckedCodeDefaults(AnnotationMirror absoluteDefaultAnno,
                                   TypeUseLocation[] locations)

addElementDefault

public void addElementDefault(Element elem,
                              AnnotationMirror elementDefaultAnno,
                              TypeUseLocation location)

Sets the default annotations for a certain Element.

annotate

public void annotate(Element elt,
                     AnnotatedTypeMirror type)

Applies default annotations to a type given an Element.

Parameters:

elt - the element from which the type was obtained

type - the type to annotate

annotate

public void annotate(Tree tree,
                     AnnotatedTypeMirror type)

Applies default annotations to a type given a Tree.

Parameters:

tree - the tree from which the type was obtained

type - the type to annotate

applyUncheckedCodeDefaults

public boolean applyUncheckedCodeDefaults(Element annotationScope)

Given an element, returns whether the unchecked code default (i.e. conservative defaults) should be applied for it. Handles elements from bytecode or source code.

createDefaultApplierElement

protected QualifierDefaults.DefaultApplierElement createDefaultApplierElement(AnnotatedTypeFactory atypeFactory,
                                                                              Element annotationScope,
                                                                              AnnotatedTypeMirror type,
                                                                              boolean applyToTypeVar)

getWildcardBoundType

public static org.checkerframework.framework.util.defaults.QualifierDefaults.BoundType getWildcardBoundType(AnnotatedTypeMirror.AnnotatedWildcardType annotatedWildcard,
                                                                                                            AnnotatedTypeFactory typeFactory)

Returns:

the BoundType of annotatedWildcard. If it is unbounded, use the type parameter to which its an argument.
