Message Debug

Debug block for the message passing system.

The message debug block is used to capture and print or store messages as they are received. Any block that generates a message may connect that message port to one or more of the three message input ports of this debug block.

The message ports are:

• print: prints the message directly to standard out.
• store: stores the message in an internal vector. It works in conjunction with a message_debug::get_message(size_t i) call that allows us to retrieve message i afterward.
• print_pdu: specifically designed to handle formatted PDUs (see pdu.h). It discards messages that aren't PDU pairs (or are null).

Parameters

None

Example Flowgraph

In this example, a Message Strobe block sends the string "Demo" once per second. It is displayed on the user terminal by the Message Debug block.
