Overview

Generic Decode class All Decoders inherit from this class and have to implement the find_segments method, using @data, @begin_offset and @end_offset instance variables to parse data. Here is the DSL Decoders can use in their find_segments method:

  • *@data* (IOBlockReader): The data to be accessed

  • *@begin_offset* (Fixnum): The begin offset

  • *@end_offset* (Fixnum): The end offset

  • found_segment: Method used to indicate a Segment was successfully parsed

  • keep_alive: Method used to indicate progression
