Interface IAnnotationHandle

All Known Implementing Classes:

Annotations.Handle

public interface IAnnotationHandle

Interface for annotation handle since some classes may need to read info from both ASM AnnotationNodes at runtime and mirror annotations in the AP at compile time.

Method Summary

Modifier and Type	Method and Description
boolean	exists() Get whether the annotation inside the handle actually exists, if the contained element is null, returns false.
IAnnotationHandle	getAnnotation(java.lang.String key) Get an annotation value as an annotation handle
java.util.List<IAnnotationHandle>	getAnnotationList(java.lang.String key) Retrieve an annotation key as a list of annotation handles
java.lang.String	getDesc() Get the annotation descriptor
<T> java.util.List<T>	getList(java.lang.String key) Retrieve the annotation value with the specified key as a list with values of the specified type.
java.util.List<org.objectweb.asm.Type>	getTypeList(java.lang.String key) Retrieve an annotation key as a list of Types.
org.objectweb.asm.Type	getTypeValue(java.lang.String key) Get an annotation value as an ASM Type.
<T> T	getValue() Get the annotation value or return null if not present or not set
<T> T	getValue(java.lang.String key) Get the annotation value with the specified key or return null if not present or not set
<T> T	getValue(java.lang.String key, T defaultValue) Get a value with the specified key from this annotation, return the specified default value if the key is not set or is not present

Method Detail

exists

boolean exists()

Get whether the annotation inside the handle actually exists, if the contained element is null, returns false.

Returns:

true if the annotation exists

getDesc

java.lang.String getDesc()

Get the annotation descriptor

getAnnotationList

java.util.List<IAnnotationHandle> getAnnotationList(java.lang.String key)

Retrieve an annotation key as a list of annotation handles

Parameters:

key - key to fetch

Returns:

list of annotations

getTypeValue

org.objectweb.asm.Type getTypeValue(java.lang.String key)

Get an annotation value as an ASM Type. This is special-cased because the different APIs return class literals in different ways. Under ASM we will receieve Type instances, but at compile time we will get TypeMirrors instead. This overload is provided so that subclasses have to marshal everything into Type for consistency.

Parameters:

key - key to fetch

Returns:

value

getTypeList

java.util.List<org.objectweb.asm.Type> getTypeList(java.lang.String key)

Retrieve an annotation key as a list of Types. This is special-cased because the different APIs return class literals in different ways. Under ASM we will receieve Type instances, but at compile time we will get TypeMirrors instead. This overload is provided so that subclasses have to marshal everything into Type for consistency.

Parameters:

key - key to fetch

Returns:

list of types

getAnnotation

IAnnotationHandle getAnnotation(java.lang.String key)

Get an annotation value as an annotation handle

Parameters:

key - key to search for in the value map

Returns:

value or null if not set

getValue

<T> T getValue(java.lang.String key,
               T defaultValue)

Get a value with the specified key from this annotation, return the specified default value if the key is not set or is not present

Type Parameters:

T - duck type

Parameters:

key - key

defaultValue - value to return if the key is not set or not present

Returns:

value or default if not set

getValue

<T> T getValue()

Get the annotation value or return null if not present or not set

Type Parameters:

T - duck type

Returns:

value or null if not present or not set

getValue

<T> T getValue(java.lang.String key)

Get the annotation value with the specified key or return null if not present or not set

Type Parameters:

T - duck type

Parameters:

key - key to fetch

Returns:

value or null if not present or not set

getList

<T> java.util.List<T> getList(java.lang.String key)

Retrieve the annotation value with the specified key as a list with values of the specified type. Returns an empty list if the value is not present or not set.

Type Parameters:

T - list element duck type

Parameters:

key - key to fetch

Returns:

list of values
