Methods Summary

Methods
Type Params	Return Type	Name and description
	`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`	`equals(Object obj)` {@inheritDoc}
	`public MetaClass`	`getAdaptee()` Returns the wrapped meta class.
	`public Object`	`getAttribute(Object object, String attribute)` Retrieves an attribute of an instance of the class returned by the getTheClass() method. What this means is largely down to the MetaClass implementation, however the default case would result in attempt to read a field of the instance. See Also: MetaClassImpl Parameters: `object` - An instance of the class returned by the getTheClass() method `attribute` - The name of the attribute to retrieve the value for Returns: The attribute value
	`public Object`	`getAttribute(Class sender, Object receiver, String messageName, boolean useSuper)` Retrieves the value of an attribute (field). This method is to support the Groovy runtime and not for general client API usage.

    newValue - The new value of the attribute
  - public void setAttribute(Class sender, Object receiver, String messageName, Object messageValue, boolean useSuper, boolean fromInsideClass)
    
    Sets the value of an attribute (field). This method is to support the Groovy runtime and not for general client API usage.
    Parameters:
    sender - The class of the object that requested the attribute
    receiver - The instance
    messageName - The name of the attribute
    messageValue - The value of the attribute
    useSuper - Whether to look-up on the super class or not
    fromInsideClass - Whether the call happened from the inside or the outside of a class
  - public void setMetaClass(MetaClass metaClass)
    
    Allows the MetaClass to be replaced with a derived implementation.
    Parameters:
    metaClass - the new metaclass
  - public void setProperty(Object object, String property, Object newValue)
    
    Sets a property of an instance of the class returned by the getTheClass() method.
    What this means is largely down to the MetaClass implementation, however the default case would result in an attempt to invoke a JavaBean setter, or if no such setter exists to set a public field of the instance.
    See Also:
    MetaClassImpl
    Parameters:
    object - An instance of the class returned by the getTheClass() method
    property - The name of the property to set
    newValue - The new value of the property
  - public void setProperty(Class sender, Object receiver, String messageName, Object messageValue, boolean useSuper, boolean fromInsideClass)
    
    Sets a property on the given receiver for the specified arguments. The sender is the class that is setting the property from the object. The MetaClass will attempt to establish the method to invoke based on the name and arguments provided.
    The isCallToSuper and fromInsideClass help the Groovy runtime perform optimisations on the call to go directly to the super class if necessary
    Parameters:
    sender - The java.lang.Class instance that is mutating the property
    receiver - The Object which the property is being set on
    property - The name of the property
    value - The new value of the property to set
    isCallToSuper - Whether the call is to a super class property
    fromInsideClass - Whether the call was invoked from the inside or the outside of the class
  - public void setProperty(String property, Object newValue)
    
    Sets the given property to the new value.
    Parameters:
    propertyName - the name of the property of interest
    newValue - the new value for the property
  - public String toString()
