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.

Parameters

(R): Run-time adjustable

Added in 3.9

PDU Vectors (R): On or Off - determines if the uniform vector is printed or not.

Version 3.8

None

Messages

Inputs

Versions 3.9 and 3.10

print: Prints all messages to standard out. If the message is a PDU, it will receive special formatting and the PDU Vectors block parameter will determine if the uniform vector is printed or not.
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. This is included for compatibility and is no longer recommended for use.

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).

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.
