Constructor Details

NonNullDefaultAwareTypeAnnotationWalker

public NonNullDefaultAwareTypeAnnotationWalker(IBinaryTypeAnnotation[] typeAnnotations,
 int defaultNullness,
 LookupEnvironment environment)

Create initial walker with non-empty type annotations.

NonNullDefaultAwareTypeAnnotationWalker

public NonNullDefaultAwareTypeAnnotationWalker(int defaultNullness,
 LookupEnvironment environment)

Create an initial walker without 'real' type annotations, but with a nonnull default.

Method Details

restrict

protected TypeAnnotationWalker restrict(long newMatches,
 int newPathPtr)

Overrides:

restrict in class TypeAnnotationWalker

toSupertype

public ITypeAnnotationWalker toSupertype(short index,
 char[] superTypeSignature)

Description copied from class: TypeAnnotationWalker

Walk to the specified supertype either index based or name based:

(superTypesSignature is ignored in this implementation).

Specified by:

toSupertype in interface ITypeAnnotationWalker

Overrides:

toSupertype in class TypeAnnotationWalker

Parameters:

index - -1 is superclass, else index into the list of superinterfaces

superTypeSignature - name and type arguments of the super type to visit

toMethodParameter

public ITypeAnnotationWalker toMethodParameter(short index)

Description copied from interface: ITypeAnnotationWalker

Walk to the index'th visible formal method parameter (i.e., not counting synthetic args).

Specified by:

toMethodParameter in interface ITypeAnnotationWalker

Overrides:

toMethodParameter in class TypeAnnotationWalker

toField

public ITypeAnnotationWalker toField()

Description copied from interface: ITypeAnnotationWalker

Walk to a field.

Specified by:

toField in interface ITypeAnnotationWalker

Overrides:

toField in class TypeAnnotationWalker

toMethodReturn

public ITypeAnnotationWalker toMethodReturn()

Description copied from interface: ITypeAnnotationWalker

Walk to the return type of a method.

Specified by:

toMethodReturn in interface ITypeAnnotationWalker

Overrides:

toMethodReturn in class TypeAnnotationWalker

toTypeBound

public ITypeAnnotationWalker toTypeBound(short boundIndex)

Description copied from interface: ITypeAnnotationWalker

Detail of ITypeAnnotationWalker.toTypeParameterBounds(boolean, int): walk to the bounds of the previously selected type parameter.

Specified by:

toTypeBound in interface ITypeAnnotationWalker

Overrides:

toTypeBound in class TypeAnnotationWalker

toWildcardBound

public ITypeAnnotationWalker toWildcardBound()

Description copied from interface: ITypeAnnotationWalker

Walk to the bound of a wildcard.

Specified by:

toWildcardBound in interface ITypeAnnotationWalker

Overrides:

toWildcardBound in class TypeAnnotationWalker

toTypeParameterBounds

public ITypeAnnotationWalker toTypeParameterBounds(boolean isClassTypeParameter,
 int parameterRank)

Description copied from interface: ITypeAnnotationWalker

Walk to the bounds of a type parameter of either a class or a method (signaled by isClassTypeParameter). Clients must then call ITypeAnnotationWalker.toTypeBound(short) on the resulting walker.

Specified by:

toTypeParameterBounds in interface ITypeAnnotationWalker

Overrides:

toTypeParameterBounds in class TypeAnnotationWalker

Parameters:

isClassTypeParameter - whether we are looking at a class type parameter (else: method type parameter)

parameterRank - rank of the type parameter.

toTypeArgument

public ITypeAnnotationWalker toTypeArgument(int rank)

Description copied from interface: ITypeAnnotationWalker

Walk to the type argument of the given rank.

Specified by:

toTypeArgument in interface ITypeAnnotationWalker

Overrides:

toTypeArgument in class TypeAnnotationWalker

toTypeParameter

public ITypeAnnotationWalker toTypeParameter(boolean isClassTypeParameter,
 int rank)

Description copied from interface: ITypeAnnotationWalker

Walk to the type parameter of the given rank.

Specified by:

toTypeParameter in interface ITypeAnnotationWalker

Overrides:

toTypeParameter in class TypeAnnotationWalker

Parameters:

isClassTypeParameter - whether we are looking for a class type parameter (else: method type parameter)

rank - rank of the type parameter

toNextDetail

protected ITypeAnnotationWalker toNextDetail(int detailKind)

Overrides:

toNextDetail in class TypeAnnotationWalker

getAnnotationsAtCursor

public IBinaryAnnotation[] getAnnotationsAtCursor(int currentTypeId,

Specified by:

getAnnotationsAtCursor in interface ITypeAnnotationWalker

Overrides:

getAnnotationsAtCursor in class TypeAnnotationWalker

Parameters:

currentTypeId - the id of the type being annotated; 0 signals don't care / unknown; -1 signals if annotating a wildcard or a use of a type variable.

Descend down one level of array dimensions.

Specified by:

toNextArrayDimension in interface ITypeAnnotationWalker

Overrides:

toNextArrayDimension in class TypeAnnotationWalker
