Object-oriented framework for creating and using container objects with built-in properties
First Claim
1. A method for organizing information in a memory of a computer system, the memory having an address space for an object-oriented operating system and an address space for an application program, the method comprising the steps of:
- (a) storing information defining a container class in the operating system address space of the memory, the container class being comprised of a data structure for holding information, a member function for constructing a container object from the container class, a first member function for inserting information identifying a containable object into the data structure, plurality of member functions for performing editing operations and a second member function for inserting information identifying an editing operation into the data structure;
(b) executing the constructing member function to instantiate a container object in the application program address space of the memory;
(c) executing the first inserting member function of the instantiated container object to insert information identifying a containable object into the data structure of the instantiated container object;
(d) executing one of the editing member functions in the instantiated container object to perform an editing operation on the containable object identified by information in the data structure of the instantiated container object; and
(e) executing the second inserting member function to insert information identifying the editing operation performed in step (d) into the data structure of the instantiated container object so that the editing operation may be undone and redone.

Abstract
An object-oriented framework is used to create container objects which are, in turn, used to hold both other objects and information in order to organize the information in a variety of ways. The framework contains a set of pre-defined class information which allows container objects to be constructed or instantiated. An instantiated container object can be accessed by a multitude of users and may contain other objects which can hold information defining other containers, such as shelves and trash cans, or which can hold information representing physical "things" such as locations, maps and people. The pre-defined class information includes member functions which provide default editing operations such as cut, copy, paste, drag, drop, selection, move, undo and redo, which editing operations are applicable to all objects in the container. Member functions are also provided to generate one or more presentations on a display which represent the container.

12. A system for organizing information in a memory of a computer system, the memory having an address space for an object-oriented operating system and an address space for an application program, the system comprising:
-
(a) means for storing information defining a container class in the operating system address space in the memory, the container class being comprised of a data structure for holding information, a member function for constructing a container object from the container class, a first member function for inserting information identifying a containable object into the data structure, a plurality of member functions for performing editing operations and a second member function for inserting information identifying an editing operation into the data structure; (b) means controlled by the application program for executing the constructing member function to instantiate a container object in the application program address space of the memory; (c) means controlled by the application program for executing the first inserting member function to insert information identifying a containable object into the data structure of the instantiated container object; (d) means controlled by the application program for executing one of the editing member functions in the instantiated container object to perform an editing operation on the containable object identified by information in the data structure of the instantiated container object; and (e) means responsive to a particular editing operation for executing the second inserting member function to insert information identifying the particular editing operation into the data structure of the instantiated container object so that the editing operation may be undone and redone. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A container framework for use in a computer system having a processor, a volatile memory, a non-volatile memory having a plurality of separate volumes and a plurality of objects, each of the plurality of objects having object model information stored in the volatile memory and object model store information stored in one of the plurality of non-volatile memory volumes, the container framework comprising:
-
means for constructing a container object, the container object having a container model stored in the volatile memory and a container model store stored in the non-volatile memory; means for inserting each of the plurality of objects into the container object, the inserting means comprising means for copying object model information for the each object into the container model and means for linking the container model information and the object model information into a containment hierarchy. - View Dependent Claims (24)
