```
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

Since:

1.5

- Method Detail
  - isModified
```
boolean isModified()
```
    Return whether the MetaClass has been modified or not
    
    Returns:
    
    True if it has
  - addNewInstanceMethod
```
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
  - addNewStaticMethod
```
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
  - 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
