Examples of avrora.core.SourceMapping

avrora.core.SourceMapping
The SourceMapping class embodies the concept of mapping machine code level addresses and constructions in the Program class back to a source code program, either in assembly language (labels), or a high-level programming lagnguage like C. This class is used by the simulator to report information about the program in a higher-level way more readibly understandable, for example to report calls / returns between functions by their names rather than their machine code addresses. @author Ben L.
