Thank you - that is actually a really clear example. I thought that more
information than that was going with the protobuf, or that more
intelligence was built into the parsing than is.
What I'm trying at the moment is just adding a first field to all of the
messages in this set that is a string of the type of the message, in which
case my example above becomes:
void CModule::ProcessMessages( CMOOSMsg &msg )
{
// Declare message types
MyMessages::TypeA type_a;
MyMessages::TypeB type_b;
// Parse a message of type A
if( type_a.ParseFromString( msg.GetString() ) && ( type_a.type() ==
"TypeA" ) )
{
printf( "Received a message of type A\n" );
}
// Parse a message of type B
else if( type_b.ParseFromString( msg.GetString() ) && ( type_b.type() ==
"TypeB" ) )
{
printf( "Received a message of type B\n" );
}
else
{
printf( "ERROR: Unrecognized message type" );
}
}
Perhaps not the most elegant solution, but if I understand how things work
now I think that it should solve my issue.
