Method Detail

exists

public boolean exists()

Description copied from interface: IAnnotationHandle

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

Specified by:

exists in interface IAnnotationHandle

Returns:

true if the annotation exists

getNode

public org.objectweb.asm.tree.AnnotationNode getNode()

getDesc

public java.lang.String getDesc()

Description copied from interface: IAnnotationHandle

Get the annotation descriptor

Specified by:

getDesc in interface IAnnotationHandle

getAnnotationList

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

Description copied from interface: IAnnotationHandle

Retrieve an annotation key as a list of annotation handles

Specified by:

getAnnotationList in interface IAnnotationHandle

Parameters:

key - key to fetch

Returns:

list of annotations

getTypeValue

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

Description copied from interface: IAnnotationHandle

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.

Specified by:

getTypeValue in interface IAnnotationHandle

Parameters:

key - key to fetch

Returns:

value

getTypeList

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

Description copied from interface: IAnnotationHandle

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.

Specified by:

getTypeList in interface IAnnotationHandle

Parameters:

key - key to fetch

Returns:

list of types

getAnnotation

public IAnnotationHandle getAnnotation(java.lang.String key)

Description copied from interface: IAnnotationHandle

Get an annotation value as an annotation handle

Specified by:

getAnnotation in interface IAnnotationHandle

Parameters:

key - key to search for in the value map

Returns:

value or null if not set

getValue

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

Description copied from interface: IAnnotationHandle

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

Specified by:

getValue in interface IAnnotationHandle

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

public <T> T getValue()

Description copied from interface: IAnnotationHandle

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

Specified by:

getValue in interface IAnnotationHandle

Type Parameters:

T - duck type

Returns:

value or null if not present or not set

getValue

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

Description copied from interface: IAnnotationHandle

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

Specified by:

getValue in interface IAnnotationHandle

Type Parameters:

T - duck type

Parameters:

key - key to fetch

Returns:

value or null if not present or not set

getList

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

Description copied from interface: IAnnotationHandle

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.

Specified by:

getList in interface IAnnotationHandle

Type Parameters:

T - list element duck type

Parameters:

key - key to fetch

Returns:

list of values

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
