getMethodName

public java.lang.String getMethodName()

Description copied from interface: MethodMetadata

Return the name of the method.

Specified by:

getMethodName 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(java.lang.String annotationType)

Description copied from interface: MethodMetadata

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

Specified by:

isAnnotated in interface MethodMetadata

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: MethodMetadata

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

Specified by:

getAnnotationAttributes in interface MethodMetadata

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.

getDeclaringClassName

public java.lang.String getDeclaringClassName()

Description copied from interface: MethodMetadata

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

Specified by:

getDeclaringClassName in interface MethodMetadata
