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.

Parameters

None

Messages

Inputs

Applies to Version 3.8


print
Prints the message 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).

Applies to Version 3.9


print
Prints all messages to standard out. They can be either PMT or PDU messages.
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
PDU messages are redirected to the 'print' port

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.
