Constructor Detail

StandardAnnotationMetadata

@Deprecated
public StandardAnnotationMetadata(Class<?> introspectedClass)

Deprecated. since 5.2 in favor of the factory method AnnotationMetadata.introspect(Class)

Create a new StandardAnnotationMetadata wrapper for the given Class.

Parameters:

introspectedClass - the Class to introspect

See Also:

StandardAnnotationMetadata(Class, boolean)

StandardAnnotationMetadata

@Deprecated
public StandardAnnotationMetadata(Class<?> introspectedClass,
                                              boolean nestedAnnotationsAsMap)

Deprecated. since 5.2 in favor of the factory method AnnotationMetadata.introspect(Class). Use MergedAnnotation.asMap from getAnnotations() rather than AnnotatedTypeMetadata.getAnnotationAttributes(String) if nestedAnnotationsAsMap is false

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 introspect

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

Since:

3.1.1

Method Detail

getAnnotations

public MergedAnnotations getAnnotations()

Description copied from interface: AnnotatedTypeMetadata

Return annotation details based on the direct annotations of the underlying element.

Specified by:

getAnnotations in interface AnnotatedTypeMetadata

Returns:

merged annotations based on the direct annotations

getAnnotationTypes

public Set<String> getAnnotationTypes()

Description copied from interface: AnnotationMetadata

Get the fully qualified class names of all annotation types that are present on the underlying class.

Specified by:

getAnnotationTypes in interface AnnotationMetadata

Returns:

the annotation type names

getAnnotationAttributes

@Nullable
public Map<String,Object> getAnnotationAttributes(String annotationName,
                                                            boolean classValuesAsString)

Description copied from interface: AnnotatedTypeMetadata

Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying element, as direct annotation or meta-annotation), also taking attribute overrides on composed annotations into account.

Specified by:

getAnnotationAttributes in interface AnnotatedTypeMetadata

Parameters:

annotationName - the fully qualified class name of 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.

getAllAnnotationAttributes

@Nullable
public MultiValueMap<String,Object> getAllAnnotationAttributes(String annotationName,
                                                                         boolean classValuesAsString)

Description copied from interface: AnnotatedTypeMetadata

Retrieve all attributes of all annotations of the given type, if any (i.e. if defined on the underlying element, as direct annotation or meta-annotation). Note that this variant does not take attribute overrides into account.

Specified by:

getAllAnnotationAttributes in interface AnnotatedTypeMetadata

Parameters:

annotationName - the fully qualified class name of the annotation type to look for

classValuesAsString - whether to convert class references to String

Returns:

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

See Also:

AnnotatedTypeMetadata.getAllAnnotationAttributes(String)

hasAnnotatedMethods

public boolean hasAnnotatedMethods(String annotationName)

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

Parameters:

annotationName - the fully qualified class name of the annotation type to look for

getAnnotatedMethods

public Set<MethodMetadata> getAnnotatedMethods(String annotationName)

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, AnnotatedTypeMetadata.isAnnotated(java.lang.String) will return true for the given annotation type.

Specified by:

getAnnotatedMethods in interface AnnotationMetadata

Parameters:

annotationName - the fully qualified class name of 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.
