Patent US 7,971,189

An automated interaction diagram generation using source code breakpoints is presented. A user sets diagram breakpoints at locations in source code using an integrated development environment (IDE) that includes a diagram generation manager. The user sets the breakpoints at locations where the user wishes to capture the interaction between objects on an interaction diagram. The IDE executes the code and the diagram generation manager collects breakpoint data corresponding to the breakpoints. Once the source code finishes executing, the diagram generation manager formats the breakpoint data and generates an interaction diagram based upon the formatted breakpoint data. The user may instruct the diagram generation manager to add or remove detail from the interaction diagram by adjusting breakpoint attributes and/or adding/deleting breakpoints.
