StandardMethodMetadata

public StandardMethodMetadata(Method introspectedMethod)

Create a new StandardMethodMetadata wrapper for the given Method.

参数:

introspectedMethod - the Method to introspect

StandardMethodMetadata

public StandardMethodMetadata(Method introspectedMethod,
                              boolean nestedAnnotationsAsMap)

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

参数:

introspectedMethod - the Method to introspect

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

3.1.1

方法详细资料

getIntrospectedMethod

public final Method getIntrospectedMethod()

Return the underlying Method.

getMethodName

public String getMethodName()

从接口复制的说明: MethodMetadata

Return the name of the method.

指定者:

getMethodName 在接口中 MethodMetadata

getDeclaringClassName

public String getDeclaringClassName()

从接口复制的说明: MethodMetadata

Return the fully-qualified name of the class that declares this method.

指定者:

getDeclaringClassName 在接口中 MethodMetadata

getReturnTypeName

public String getReturnTypeName()

从接口复制的说明: MethodMetadata

Return the fully-qualified name of this method's declared return type.

指定者:

getReturnTypeName 在接口中 MethodMetadata

isAbstract

public boolean isAbstract()

从接口复制的说明: 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.

指定者:

isAbstract 在接口中 MethodMetadata

isStatic

public boolean isStatic()

从接口复制的说明: MethodMetadata

Return whether the underlying method is declared as 'static'.

指定者:

isStatic 在接口中 MethodMetadata

isFinal

public boolean isFinal()

从接口复制的说明: MethodMetadata

Return whether the underlying method is marked as 'final'.

指定者:

isFinal 在接口中 MethodMetadata

isOverridable

public boolean isOverridable()

从接口复制的说明: MethodMetadata

Return whether the underlying method is overridable, i.e. not marked as static, final or private.

指定者:

isOverridable 在接口中 MethodMetadata

isAnnotated

public boolean isAnnotated(String annotationName)

从接口复制的说明: 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.

指定者:

isAnnotated 在接口中 AnnotatedTypeMetadata

参数:

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

返回:

whether a matching annotation is defined

getAnnotationAttributes

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

从接口复制的说明: 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.

指定者:

getAnnotationAttributes 在接口中 AnnotatedTypeMetadata

参数:

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

返回:

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

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

从接口复制的说明: 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.

指定者:

getAnnotationAttributes 在接口中 AnnotatedTypeMetadata

参数:

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

返回:

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)

从接口复制的说明: 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.

指定者:

getAllAnnotationAttributes 在接口中 AnnotatedTypeMetadata

参数:

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

返回:

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.

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.

指定者:

getAllAnnotationAttributes 在接口中 AnnotatedTypeMetadata

参数:

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

classValuesAsString - whether to convert class references to String

返回:

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.
