Constructor Detail

StandardAnnotationMetadata

public StandardAnnotationMetadata(java.lang.Class<?> introspectedClass)

Create a new StandardAnnotationMetadata wrapper for the given Class.

Parameters:

introspectedClass - the Class to introspect

StandardAnnotationMetadata(Class, boolean)

StandardAnnotationMetadata

public StandardAnnotationMetadata(java.lang.Class<?> introspectedClass,
                          boolean nestedAnnotationsAsMap)

Create a new StandardAnnotationMetadata wrapper for the given Class, providing the option to return any nested annotations or annotation arrays in the form of AnnotationAttributes instead of actual Annotation instances.

Parameters:

introspectedClass - the Class to instrospect

nestedAnnotationsAsMap - return nested annotations and annotation arrays as AnnotationAttributes for compatibility with ASM-based AnnotationMetadata implementations

3.1.1

Method Detail

getAnnotationTypes

public java.util.Set<java.lang.String> getAnnotationTypes()

Description copied from interface: AnnotationMetadata

Return the names of all annotation types defined on the underlying class.

Specified by:

getAnnotationTypes in interface AnnotationMetadata

Returns:

the annotation type names

getMetaAnnotationTypes

public java.util.Set<java.lang.String> getMetaAnnotationTypes(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Return the names of all meta-annotation types defined on the given annotation type of the underlying class.

Specified by:

getMetaAnnotationTypes in interface AnnotationMetadata

Parameters:

annotationType - the meta-annotation type to look for

Returns:

the meta-annotation type names

hasAnnotation

public boolean hasAnnotation(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Determine whether the underlying class has an annotation of the given type defined.

Specified by:

hasAnnotation in interface AnnotationMetadata

Parameters:

annotationType - the annotation type to look for

Returns:

whether a matching annotation is defined

hasMetaAnnotation

public boolean hasMetaAnnotation(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.

Specified by:

hasMetaAnnotation in interface AnnotationMetadata

Parameters:

annotationType - the meta-annotation type to look for

Returns:

whether a matching meta-annotation is defined

isAnnotated

public boolean isAnnotated(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Determine whether the underlying class has an annotation or meta-annotation of the given type defined.

This is equivalent to a "hasAnnotation || hasMetaAnnotation" check. If this method returns true, then AnnotationMetadata.getAnnotationAttributes(java.lang.String) will return a non-null Map.

Specified by:

isAnnotated in interface AnnotationMetadata

Parameters:

annotationType - the annotation type to look for

Returns:

whether a matching annotation is defined

getAnnotationAttributes

public java.util.Map<java.lang.String,java.lang.Object> getAnnotationAttributes(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying class, as direct annotation or as meta-annotation).

Specified by:

getAnnotationAttributes in interface AnnotationMetadata

Parameters:

annotationType - the annotation type to look for

Returns:

a Map of attributes, with the attribute name as key (e.g. "value") and the defined attribute value as Map value. This return value will be null if no matching annotation is defined.

getAnnotationAttributes

public java.util.Map<java.lang.String,java.lang.Object> getAnnotationAttributes(java.lang.String annotationType,
                                                                       boolean classValuesAsString)

Description copied from interface: AnnotationMetadata

Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying class, as direct annotation or as meta-annotation).

Specified by:

getAnnotationAttributes in interface AnnotationMetadata

Parameters:

annotationType - the annotation type to look for

classValuesAsString - whether to convert class references to String class names for exposure as values in the returned Map, instead of Class references which might potentially have to be loaded first

Returns:

a Map of attributes, with the attribute name as key (e.g. "value") and the defined attribute value as Map value. This return value will be null if no matching annotation is defined.

hasAnnotatedMethods

public boolean hasAnnotatedMethods(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Determine whether the underlying class has any methods that are annotated (or meta-annotated) with the given annotation type.

Specified by:

hasAnnotatedMethods in interface AnnotationMetadata

getAnnotatedMethods

public java.util.Set<MethodMetadata> getAnnotatedMethods(java.lang.String annotationType)

Description copied from interface: AnnotationMetadata

Retrieve the method metadata for all methods that are annotated (or meta-annotated) with the given annotation type.

For any returned method, MethodMetadata.isAnnotated(java.lang.String) will return true for the given annotation type.

Specified by:

getAnnotatedMethods in interface AnnotationMetadata

Parameters:

annotationType - the annotation type to look for

Returns:

a Set of MethodMetadata for methods that have a matching annotation. The return value will be an empty set if no methods match the annotation type.
