[Java] Interface MutableMetaClass

groovy.lang.MetaObjectProtocol

All Superinterfaces:: MetaClass, MetaObjectProtocol

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

See Also:: MetaClassImpl; MetaClass

Method Detail

public void addMetaBeanProperty(MetaBeanProperty metaBeanProperty)

Adds a new MetaBeanProperty to the MetaClass

Parameters:: metaBeanProperty - The MetaBeanProperty instance

public void addMetaMethod(MetaMethod metaMethod)

Adds a new MetaMethod to the MetaClass

Parameters:: metaMethod - The MetaMethod to add

public void addNewInstanceMethod(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

public void addNewStaticMethod(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

public boolean isModified()

Return whether the MetaClass has been modified or not

Returns:: True if it has
