Class SimpleQualifierParameterAnnotationConverter<Q>

java.lang.Object

org.checkerframework.qualframework.poly.SimpleQualifierParameterAnnotationConverter<Q>

All Implemented Interfaces:

AnnotationConverter<QualParams<Q>>, QualifierParameterAnnotationConverter<Q>

Direct Known Subclasses:

RegexAnnotationConverter, TaintingAnnotationConverter

public abstract class SimpleQualifierParameterAnnotationConverter<Q>
extends Object
implements QualifierParameterAnnotationConverter<Q>

SimpleQualifierParameterAnnotationConverter abstracts the logic to convert annotations to qualifiers for typical qual-poly types systems that that support @Wild, @Var, and qualifier parameters. getQualifier(javax.lang.model.element.AnnotationMirror) should be implemented to convert an annotation to a type system specific qualifier (e.g. @Regex or @Tainted).

Constructor Detail

SimpleQualifierParameterAnnotationConverter

public SimpleQualifierParameterAnnotationConverter(AnnotationConverterConfiguration<Q> config)

Construct a SimpleQualifierParameterAnnotationConverter.

Method Detail

getQualifier

public abstract Q getQualifier(AnnotationMirror anno)

Create a type system qualifier based on an annotation.

Parameters:

anno - the annotation

Returns:

the resulting qualifier

specialCaseHandle

protected QualParams<Q> specialCaseHandle(AnnotationMirror anno)

Special case handle the AnnotationMirror. Useful for when more control is need when processing an annotation.

fromAnnotations

public QualParams<Q> fromAnnotations(Collection<? extends AnnotationMirror> annos)

Convert a list of AnnotationMirrors to a QualParams. Each AnnotationMirror is converted into a QualParams. The resulting QualParams are merged together to create the result. If no primary qualifier is found, DEFAULT_QUAL will be used.

Specified by:

fromAnnotations in interface AnnotationConverter<QualParams<Q>>

Parameters:

annos - the collection of type annotations to parse

Returns:

the QualParams

isAnnotationSupported

public boolean isAnnotationSupported(AnnotationMirror anno)

Description copied from interface: AnnotationConverter

Checks if an annotation is supported by the current type system. This method should return true if the presence of the provided AnnotationMirror could affect the result of fromAnnotations.

Specified by:

isAnnotationSupported in interface AnnotationConverter<QualParams<Q>>

Parameters:

anno - the annotation to check

Returns:

true if the annotation is supported

getDeclaredParameters

public Set<String> getDeclaredParameters(Element elt,
                                         Set<AnnotationMirror> declAnnotations,
                                         ExtendedTypeMirror type)

Description copied from interface: QualifierParameterAnnotationConverter

Get the names of all parameters declared on a class, interface, enum, or method declaration Element.

Specified by:

getDeclaredParameters in interface QualifierParameterAnnotationConverter<Q>

Parameters:

elt - the element to inspect for parameters

declAnnotations - the declaration annotations on elt

type - the ExtendedTypeMirror for the element, after stub file annotations have been applied

Returns:

the list of declared parameters

hasPolyAnnotationCheck

protected boolean hasPolyAnnotationCheck(ExtendedTypeMirror type)

Returns:

true if type has a polymorphic qualifier.
