PRODUCER GRAPH ORIENTED PROGRAMMING FRAMEWORK WITH UNDO, REDO, AND ABORT EXECUTION SUPPORT

摘要

A method and apparatus for providing native undo, redo, and abort execution abilities of a runtime is disclosed. In one embodiment, a system includes a runtime to run object-oriented source code with producer dependency declarations for methods, wherein a producer is an instance and a method of that instance, wherein each producer dependency declaration for a given method identifies a set of zero or more producers with outputs that are an input to the given method. According to one embodiment of the invention, the runtime includes a client code tracking module to track the client code commands being run by the runtime. Furthermore, in one embodiment, the runtime also includes a runtime tracking module to track processes of the runtime performed in response to the client code commands being tracked and run by the runtime.
