The +configuration of individual objects (i.e., instance-specific methods, mixed-in +classes, etc.) may be controlled with the \fBoo::objdefine\fR command. +.PP +Each object has a unique namespace associated with it, the instance namespace. +This namespace holds all the instance variables of the object, and will be the +current namespace whenever a method of the object is invoked (including a +method of the class of the object). When the object is destroyed, its instance +namespace is deleted. The instance namespace contains the object's \fBmy\fR +command, which may be used to invoke non-exported methods of the object or to +create a reference to the object for the purpose of invokation which persists +across renamings of the object. .SS CONSTRUCTOR The \fBoo::object\fR class does not define an explicit constructor. .SS DESTRUCTOR |
