ABSTRACT:
A technique for permitting tracepoints to be set relative to data components of object oriented programs for debugging purposes is disclosed. A new method is created or an existing method is modified in an object which contains data relative to which tracing is desired. The new or modified method intercepts a message intended to access the designated data, and depending on the type of access being attempted and/or other conditions set by the developer, tracing may be initiated, modified, or terminated. Tracing is controlled by forwarding an appropriate message to a trace manager. The read or write operation is preserved by the newly created access method, which performs the desired access of the data component.
