Detailed Description

Nodelet for counting messages and their size.

ROS parameters:

~in_queue_size (uint, default 1000): Queue size for the subscriber.
~count (uint, output parameter): The number of messages received so far.
~bytes (uint, output parameter): The size of messages received so far (in bytes).
~tcp_no_delay (bool, default False): If True, the TCP_NODELAY flag is set for the subscriber. This should decrease the latency of small messages, but might give suboptimal transmission speed for large messages.

Subscribed topics:

~input (any type): The input messages.
~reset (any type): When a message is received on this topic, the counter is reset to zero.
