The methods understood by the native nil object. All other objects in the system delegate to nil eventually. Hence, nil's methods may be invoked on all objects in the system.

Method Summary

Boolean	==(Object other) The identity operator.
Boolean	!=(Object other) The !
Object	init(Object[] initargs) This method is invoked when a new instance of the object is created using this#base_new(ATObject[]).
Object	new(Object[] initargs) Creates a new instance (a clone) of the receiver and initialises it by invoking its this#base_init(ATObject[]) method.

Method Detail

!=

Boolean !=(Object other)

The != operator which returns false only if the passed parameter equals nil.

==

Boolean ==(Object other)

The identity operator. In AmbientTalk, equality of objects is by default pointer-equality (i.e. objects are equal only if they are identical).

Returns:

by default, true if the parameter object and this object are identical, false otherwise.

init

Object init(Object[] initargs)

This method is invoked when a new instance of the object is created using this#base_new(ATObject[]). The default implementation does nothing, but can be overridden to re-initialize the cloned instance.

new

Object new(Object[] initargs)

Creates a new instance (a clone) of the receiver and initialises it by invoking its this#base_init(ATObject[]) method.
