Member Function Documentation

pmt::pmt_t gr::blocks::message_debug_impl::get_message ( int  i)
virtual

Get a message (as a PMT) from the message vector at index i.

Messages passed to the 'store' port will be stored in a vector. This function retrieves those messages by index. They are index in order of when they were received (all messages are just pushed onto the back of a vector). This is mostly useful in debugging message passing graphs and in QA code.

Parameters
iThe index in the vector for the message to retrieve.
Returns
a message at index i as a pmt_t.

Implements gr::blocks::message_debug.

int gr::blocks::message_debug_impl::num_messages ( )
virtual

Reports the number of messages received by this block.

Implements gr::blocks::message_debug.
