public interface MutableMetaClass extends MetaClass
An interface that defines methods that implementers of mutable Meta classes should specify. It provides operations to perform mutations on the MetaClass instance.Whether a MetaClass allows mutation is up to the MetaClass itself and considerations of Thread safety need to be taken into account when making a MetaClass mutable
The default implementation allows mutation of MetaClass instances before initialisation (before the initialize() method is called) but not after, thus ensuring Thread safety once a MetaClass has been constructed and placed in the registry

Method Detail
-
isModified
boolean isModified()
Return whether the MetaClass has been modified or not- Returns:
- True if it has
-
addNewInstanceMethod
void addNewInstanceMethod(java.lang.reflect.Method method)
adds a new instance method to this MetaClass. Instance methods are able to overwrite the original methods of the class. Calling this method should not be done after initialise was called.- Parameters:
method- the method to be added
-
addNewStaticMethod
void addNewStaticMethod(java.lang.reflect.Method method)
adds a new static method to this MetaClass. This is only possible as long as initialise was not called.- Parameters:
method- the method to be added
-
addMetaMethod
void addMetaMethod(MetaMethod metaMethod)
Adds a new MetaMethod to the MetaClass- Parameters:
metaMethod- The MetaMethod to add
-
addMetaBeanProperty
void addMetaBeanProperty(MetaBeanProperty metaBeanProperty)
Adds a new MetaBeanProperty to the MetaClass- Parameters:
metaBeanProperty- The MetaBeanProperty instance
