Modularizing steps within a UML user model interaction pattern

A method of generating a unified modeling language (UML) activity diagram of a UML task object, the method comprising:

• receiving a command to modify a node of a UML class diagram of the UML task object, the UML class diagram defining at least one subtask node that is associated with the UML task object, the at least one subtask node including the node, and the node defining a set of steps performed by a subtask of the node;
• and
• automatically generating the UML activity diagram to selectively include the node in the UML activity diagram or selectively omit the node from the UML activity diagram, based on the command, the UML activity diagram defining a subset of a complete ordered set of a plurality of steps, subtasks, decision blocks, and transitions between the steps, subtasks, and decision blocks performed by the UML task object,
• wherein the command to modify the node of the class diagram indicates at least one of to include a first node to the class diagram and to omit a second node from the class diagram, wherein the command indicates to include the first node to the class diagram, and wherein the generating comprises including the first node in the generated UML activity diagram.

A non-transitory computer readable storage medium having embodied thereon a program which, when executed by a computer, causes the computer to execute a method of generating a unified modeling language (UML) activity diagram of a UML task object, the method comprising:

• receiving a command to modify a node of a UML class diagram of the UML task object, the UML class diagram defining at least one subtask node that is associated with the UML task object, the at least one subtask node including the node, and the node defining a set of steps performed by a subtask of the node;
• and
• automatically generating the UML activity diagram to selectively include the node in the UML activity diagram or selectively omit the node from the UML activity diagram, based on the command, the UML activity diagram defining a subset of a complete ordered set of a plurality of steps, subtasks, decision blocks, and transitions between the steps, subtasks, and decision blocks performed by the UML task object,
• wherein the command to modify the node of the class diagram indicates at least one of to include a first node to the class diagram and to omit a second node from the class diagram, and
• wherein the command indicates to include the first node to the class diagram,
• wherein the generating comprises including the first node in the generated UML activity diagram.

An apparatus for generating a unified modeling language (UML) activity diagram of a UML task object, the apparatus comprising:

• a processor that functions as:
• a class object modification unit that receives a command to modify a node of a UML class diagram of the UML task object, the UML class diagram defining at least one subtask node that is associated with the UML task object, the at least one subtask node including the node, and the node defining a set of steps performed by a subtask of the node;
• and
• a class diagram modification unit that automatically generates the UML activity diagram to selectively include the node in the UML activity diagram or selectively omit the node from the UML activity diagram, based on the command, the UML activity diagram defining a subset of a complete ordered set of a plurality of steps, subtasks, decision blocks, and transitions between the steps, subtasks, and decision blocks performed by the UML task object,
• wherein the command to modify the node of the class diagram indicates at least one of to include a first node to the class diagram and to omit a second node from the class diagram, wherein the command indicates to include the first node to the class diagram, and wherein the generating comprises including the first node in the generated UML activity diagram.
