checker- the type-checker associated with this type factory
-
-
Method Details
-
getValueAnnotatedTypeFactory
Returns the Value Checker's annotated type factory.- Returns:
- the Value Checker's annotated type factory
-
createSupportedTypeQualifiers
Description copied from class:AnnotatedTypeFactoryReturns a mutable set of annotation classes that are supported by a checker.Subclasses may override this method to return a mutable set of their supported type qualifiers through one of the 5 approaches shown below.
Subclasses should not call this method; they should call
AnnotatedTypeFactory.getSupportedTypeQualifiers()instead.By default, a checker supports all annotations located in a subdirectory called qual that's located in the same directory as the checker. Note that only annotations defined with the
@Target({ElementType.TYPE_USE})meta-annotation (and optionally with the additional value ofElementType.TYPE_PARAMETER, but no otherElementTypevalues) are automatically considered as supported annotations.To support a different set of annotations than those in the qual subdirectory, or that have other
ElementTypevalues, see examples below.In total, there are 5 ways to indicate annotations that are supported by a checker:
- Only support annotations located in a checker's qual directory:
This is the default behavior. Simply place those annotations within the qual directory.
- Support annotations located in a checker's qual directory and a list of other
annotations:
Place those annotations within the qual directory, and override
AnnotatedTypeFactory.createSupportedTypeQualifiers()by callingAnnotatedTypeFactory.getBundledTypeQualifiers(Class...)with a varargs parameter list of the other annotations. Code example:@Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() { return getBundledTypeQualifiers(Regex.class, PartialRegex.class, RegexBottom.class, UnknownRegex.class); } - Supporting only annotations that are explicitly listed: Override
AnnotatedTypeFactory.createSupportedTypeQualifiers()and return a mutable set of the supported annotations. Code example:
The set of qualifiers returned by@Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() { return new HashSet<Class<? extends Annotation>>( Arrays.asList(A.class, B.class)); }AnnotatedTypeFactory.createSupportedTypeQualifiers()must be a fresh, mutable set. The methodsAnnotatedTypeFactory.getBundledTypeQualifiers(Class...)must return a fresh, mutable set
- Overrides:
createSupportedTypeQualifiersin classAnnotatedTypeFactory- Returns:
- the type qualifiers supported this processor, or an empty set if none
- Only support annotations located in a checker's qual directory:
-
createDependentTypesHelper
Description copied from class:GenericAnnotatedTypeFactoryCreates aDependentTypesHelperand returns it. UseGenericAnnotatedTypeFactory.getDependentTypesHelper()to access the value.- Overrides:
createDependentTypesHelperin classGenericAnnotatedTypeFactory<CFValue,CFStore, CFTransfer, CFAnalysis> - Returns:
- a new
DependentTypesHelper
-
createQualifierHierarchy
Description copied from class:AnnotatedTypeFactoryReturns theQualifierHierarchyto be used by this checker.The implementation builds the type qualifier hierarchy for the
AnnotatedTypeFactory.getSupportedTypeQualifiers()using the meta-annotations found in them. The current implementation returns an instance ofNoElementQualifierHierarchy.Subclasses must override this method if their qualifiers have elements; the method must return an implementation of
QualifierHierarchy, such asElementQualifierHierarchy.- Overrides:
createQualifierHierarchyin classAnnotatedTypeFactory- Returns:
- a QualifierHierarchy for this type system
-
isLessThan
Returns true ifleftis less thanright.- Parameters:
left- the first tree to compareright- the second tree to compare- Returns:
- is left less than right?
-
isLessThan
Returns true ifleftis less thanright.- Parameters:
left- the first value to compare (an annotation)right- the second value to compare (an expression)- Returns:
- is left less than right?
-
isLessThanByValue
Returns true ifsmaller < bigger.- Parameters:
smaller- the first value to comparebigger- the second value to comparepath- used to parse expressions strings- Returns:
smaller < bigger, using information from the Value Checker
-
isLessThanOrEqual
Returns true if left is less than or equal to right.- Parameters:
left- the first value to compareright- the second value to compare- Returns:
- is left less than or equal to right?
-
isLessThanOrEqual
Returns true if left is less than or equal to right.- Parameters:
left- the first value to compareright- the second value to compare- Returns:
- is left less than or equal to right?
-
getLessThanExpressions
Returns a sorted, modifiable list of expressions thatexpressionis less than. If theexpressionis annotated withLessThanBottom, null is returned.- Parameters:
expression- an expression- Returns:
- expressions that
expressionis less than
-
createLessThanQualifier
Creates a less than qualifier given the expressions.If expressions is null,
LessThanBottomis returned. If expressions is empty,LessThanUnknownis returned. Otherwise,@LessThan(expressions)is returned.- Parameters:
expressions- a list of expressions- Returns:
- a @LessThan qualifier with the given arguments
-
createLessThanQualifier
Returns@LessThan(expression). -
getLessThanExpressions
If the annotation is LessThan, returns a list of expressions in the annotation. If the annotation isLessThanBottom, returns null. If the annotation isLessThanUnknown, returns the empty list.- Parameters:
annotation- an annotation from the same hierarchy as LessThan- Returns:
- the list of expressions in the annotation
