  • Patent number: 6240545
    Abstract: A mechanism for setting a conditional breakpoint on all methods called by a specific instance of a class. To set the instance breakpoint, the debugger determines all of the methods that can be applied to the object type or class. In an environment in which full debugging information includes the correspondence between virtual function tables and specific classes, and full class hierarchy information, the methods are located by locating the pointer to the type's virtual function table, and from the virtual function table, locating the specific class in the debugging information. Identifying the specific type permits all of the base classes of the type to be identified in the debugging information, and from the class hierarchy information, all methods for objects of the type can be compiled.
