A method, apparatus, and article of manufacture for modeling an object-oriented system. Within the object model, a reference attribute is specified for a class and a first object is instantiated from the class. Thereafter, a reference-based association can be added to the first object using the reference attribute, wherein the reference-based association identifies a relationship between the first object and a second object.

Provided is a method, system, and program for transforming files from a source file format to a destination file format. A data structure is generated in a computer readable medium indicating available transforms from a plurality of source file formats to at least one destination file format. A graphical representation of available transforms from the source file formats to the at least one destination file format is generated based on the available transforms indicated in the data structure. User input is received indicating a selected source file having a source file format and a selected destination file having a selected destination file format, wherein the data structure indicates one available transform to transform the selected source file format to the selected destination file format. The selected source file in the source file format is transformed to the selected destination file in the destination file format.

The present invention discloses a method, apparatus, and article of manufacture for enabling interaction with one or more external computer programs from within an editor environment. The method involves passing editor input to the external program, wherein the external program evaluates the input, produces corresponding output, and transmits the output back to the editor. When the editor receives the output, it stores the output in a file and displays it on a computer monitor. By using this method, a user can not only interact with the external program from within the editor environment, but can also create an editor file that stores a listing of the input and output provided to the external program.

A method, apparatus, and article of manufacture for sending messages between objects in an object-oriented system. A reference attribute for a first object is defined, wherein the reference attribute refers to a second object. A message then may be sent from the first object to the second object using the reference attribute to route the message from the first object to the second object.

A method, apparatus, and article of manufacture which provides for sending a message to a group and the group then broadcasting the message to the members of the group within an object-oriented system. The method comprises the steps of creating a first sending object and a group in a memory of a computer, the group being comprised of one or more receiving objects, sending a first message to the first sending object, sending a second message from the first sending object to the group based on the receipt of the first message, and broadcasting the second message to every object in the group.

A method, apparatus, and article of manufacture for modeling object-oriented systems includes an object modeling tool that defines methods and event transitions in an object-oriented system and generates an executable program that exhibits the behavior of the object-oriented system and interfaces with the object-oriented system. The object modeling tool further translates the event transitions to an execution language, wraps methods written in the target language, wraps event transitions corresponding to an event, and gathers one or more wrapped events and methods into an executable program.

The present invention discloses a method, apparatus, and article of manufacture of an object-oriented tool for displaying, within one window of a monitor connected to a computer, both a graphical and textual trace of an object-oriented model during execution. The invention has three sections, an object/operation/argument selection section, a graphical trace section, and a textual trace section. The object selection section displays a list of all available objects. The graphical trace view displays a graphic of the objects passing operations back and forth. The textual trace displays a log of activity during execution.

A windowing system provides an interface between application programs and non-programmable terminal drivers. The system presents logical windows to the applications program, each of which are represented internally by at least two separate parts. The first part includes the border and non-scrollable text for a logical window, while the second part includes scrollable text for the window. Through calls to the display driver, the windowing system manipulates these separate parts so that they are displayed on the screen as a single window.
