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

Version 3.11, 3.10.6++

Log level
Sets the "log" input's log level to trace, debug, info, warning, error or critical

Messages

Inputs

Versions 3.11 (and >3.10.6.1)


log
Logs all messages to the logging system (which by default prints it to your console). Generally, this is preferred over the "print" input.
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.


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.
