Method Detail

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

Parameters:

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

rank - rank of the type parameter

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

Parameters:

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

parameterRank - rank of the type parameter.

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

toField

public ITypeAnnotationWalker toField()

Description copied from interface: ITypeAnnotationWalker

Walk to a field.

toMethodReturn

public ITypeAnnotationWalker toMethodReturn()

Description copied from interface: ITypeAnnotationWalker

Walk to the return type of a method.

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).

toThrows

public ITypeAnnotationWalker toThrows(int index)

Description copied from interface: ITypeAnnotationWalker

Walk to the throws type at the given index.

getAnnotationsAtCursor

public IBinaryAnnotation[] getAnnotationsAtCursor(int currentTypeId)

Description copied from interface: ITypeAnnotationWalker

Retrieve the type annotations at the current position reached by invocations of toXYZ() methods.

Specified by:

getAnnotationsAtCursor in interface ITypeAnnotationWalker

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.

toReceiver

public ITypeAnnotationWalker toReceiver()

Description copied from interface: ITypeAnnotationWalker

Walk to the receiver type of a method. Note: Type annotations on receiver are not currently used by the compiler.

Specified by:

toReceiver in interface ITypeAnnotationWalker

toSupertype

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

Description copied from interface: ITypeAnnotationWalker

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

Specified by:

toSupertype in interface ITypeAnnotationWalker

Parameters:

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

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

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

toWildcardBound

public ITypeAnnotationWalker toWildcardBound()

Description copied from interface: ITypeAnnotationWalker

Walk to the bound of a wildcard.

Specified by:

toWildcardBound in interface ITypeAnnotationWalker

toNextArrayDimension

public ITypeAnnotationWalker toNextArrayDimension()

Description copied from interface: ITypeAnnotationWalker

Descend down one level of array dimensions.

Specified by:

toNextArrayDimension in interface ITypeAnnotationWalker

toNextNestedType

public ITypeAnnotationWalker toNextNestedType()

Description copied from interface: ITypeAnnotationWalker

Descend down one level of type nesting.

Specified by:

toNextNestedType in interface ITypeAnnotationWalker
