Method Details

getRawType

public static Class<?> getRawType(AnnotatedType type)

Returns a raw Class for a given AnnotatedType

See Also:

• Types.getRawType(Type)

getTypeArguments

public static AnnotatedType[] getTypeArguments(AnnotatedType annotatedType)

Returns an array of annotated type arguments for a given AnnotatedType

Parameters:

annotatedType - annotated type whose annotated type arguments should be retrieved

Returns:

an array of annotated type arguments for a given AnnotatedType

getTypeBindings

public static Map<TypeVariable<?>,AnnotatedType> getTypeBindings(AnnotatedType type)

Returns a map of type bindings for a given AnnotatedType

bind

public static AnnotatedType bind(AnnotatedType annotatedType,
 Function<TypeVariable<?>,AnnotatedType> bindings)

Binds a given annotated type with actual annotated type arguments

Parameters:

annotatedType - an annotated type to be bound

bindings - a lookup function for actual annotated types

bind

public static AnnotatedType bind(AnnotatedType annotatedType,
 Function<TypeVariable<?>,AnnotatedType> bindings,
 BinaryOperator<Annotation[]> annotationCombinerFn)

Binds a given annotated type with actual annotated type arguments

Parameters:

annotatedType - an annotated type to be bound

bindings - a lookup function for actual annotated types

annotationCombinerFn - a combiner function to combine annotations of a given annotated type with annotations of bound actual annotated type

annotatedTypeOf

public static AnnotatedType annotatedTypeOf(Type type)

Constructs an AnnotatedType from a given Type. Resulting annotated type has no annotations

Parameters:

type - a type to construct annotated type from

Returns:

a new instance of AnnotatedType

annotatedTypeOf

public static AnnotatedType annotatedTypeOf(Type type,
 Annotation[] annotations)

Constructs an AnnotatedType from a given Type and an array of annotations.

Parameters:

type - a type to construct annotated type from

annotations - an array of annotations for a given type

Returns:

a new instance of AnnotatedType

annotatedTypeOf

public static AnnotatedType annotatedTypeOf(Type type,
 BiFunction<Type,int[],Annotation[]> annotationsFn)

Constructs an AnnotatedType from a given Type and a function that transforms a type and a path to the type into annotations for this type.

This method allows building complex annotated types

Parameters:

type - a type to construct annotated type from

annotationsFn - a function that transforms a type and a path to the type into annotations for this type

Returns:

a new instance of AnnotatedType
