public AnnotationVisitor visitAnnotation(String desc,
                                         boolean visible)
```
    Description copied from class: MethodVisitor
    Visits an annotation of this method.
    Overrides:
    visitAnnotation in class MethodVisitor
    Parameters:
    desc - the class descriptor of the annotation class.
    visible - true if the annotation is visible at runtime.
    Returns:
    a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.
  - getMethodName
```
public String getMethodName()
```
    Description copied from interface: MethodMetadata
    Return the name of the method.
    Specified by:
    getMethodName in interface MethodMetadata
  - isAbstract
```
public boolean isAbstract()
```
    Description copied from interface: MethodMetadata
    Return whether the underlying method is effectively abstract: i.e. marked as abstract on a class or declared as a regular, non-default method in an interface.
    Specified by:
    isAbstract in interface MethodMetadata
  - isStatic
```
public boolean isStatic()
```
    Description copied from interface: MethodMetadata
    Return whether the underlying method is declared as 'static'.
    Specified by:
    isStatic in interface MethodMetadata
  - isFinal
```
public boolean isFinal()
```
    Description copied from interface: MethodMetadata
    Return whether the underlying method is marked as 'final'.
    Specified by:
    isFinal in interface MethodMetadata
  - isOverridable
```
public boolean isOverridable()
```
    Description copied from interface: MethodMetadata
    Return whether the underlying method is overridable, i.e. not marked as static, final or private.
    Specified by:
    isOverridable in interface MethodMetadata
  - isAnnotated
```
public boolean isAnnotated(String annotationName)
```
    Description copied from interface: AnnotatedTypeMetadata
    Determine whether the underlying element has an annotation or meta-annotation of the given type defined.
    If this method returns true, then AnnotatedTypeMetadata.getAnnotationAttributes(java.lang.String) will return a non-null Map.
    Specified by:
    isAnnotated in interface AnnotatedTypeMetadata
    Parameters:
    annotationName - the fully qualified class name of the annotation type to look for
    Returns:
    whether a matching annotation is defined
  - getAnnotationAttributes
```
public AnnotationAttributes getAnnotationAttributes(String annotationName)
```
    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
    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 AnnotationAttributes 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
```
public MultiValueMap<String,Object> getAllAnnotationAttributes(String annotationName)
```
    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
    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.

    AnnotatedTypeMetadata.getAllAnnotationAttributes(String, boolean)
  - getAllAnnotationAttributes
```
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
