Detailed Description

Command Dispatcher component class.

The command dispatcher takes incoming Fw::Com packets that contain encoded commands. It extracts the opcode and looks it up in a table that is populated by components at registration time. If a component is connected to the seqCmdStatus port with the same number as the port that submitted the command, the command status will be returned.
