Abstract

A design tool for assembling component objects to form an object-based computer system application includes a declarative user input interface mechanism and a design engine. The declarative user input interface mechanism provides an input structure for the input of user declarations specifying operative interactions between component objects. The design engine automatically generates, in response to input user declarations, an application design definition modeling an application infrastructure for managing component object interactions. The design engine automatically generates, in response to input user declarations, a match between an application view field definition and a parameter of an associated component object operations. A runtime tool includes an application engine which is responsive to an application design definition and is operative at runtime automatically to create application view instances from respective application view definitions for managing runtime component object interactions for the applications.

Claims

1. A method for forming an object-based computer system comprising:

providing a first existing executable module and a second existing executable module;

determining a first operation associated with the first existing executable module;

determining a second operation associated with the second existing executable module;

determining a mapping between the first and second operations; and

managing an interaction between the first and second operations based on the mapping.

2. The method according to claim 1, wherein the first and second existing executable modules respectively comprise an executable component object.

3. The method according to claim 2 and further comprising assembling the executable component objects to form an object-based application.

4. The method according to claim 2 and further comprising managing runtime interactions between the executable component objects.

5. The method according to claim 4, wherein managing the runtime interactions comprises configuring a user interface based on the mapping for managing the runtime interactions.

6. The method according to claim 1, wherein determining the mapping comprises specifying an intermediate representation of information for communication between the first and second operations.

7. The method according to claim 6, wherein the intermediate representation is associated with a user interface.

8. The method according to claim 6, wherein the intermediate representation indicates how the first operation responds to a user interface event.

9. The method according to claim 1, wherein determining the mapping comprises determining how a parameter associated with the first operation flows to the second operation.

mapping an output parameter associated with the first operation; and

mapping an input parameter associated with the second operation.

12. The method according to claim 1, wherein the first operation has an associated field and further comprising generating a characteristic associated with the first operation based on the field and user input.
