Detailed Description

A process wide thread that handles all publishing of ROS topics of the current process. There is no strong reason why only one publisher should exist, in later implementations, one publisher thread per channel may exist as well. See the usage recommendations for Instance()

Member Typedef Documentation

typedef Publishers::iterator rtt_roscomm::RosPublishActivity::iterator [private]

Definition at line 79 of file rtt_rostopic_ros_publish_activity.hpp.

A set keeping track of all publishers in the current process. It must be guarded by the mutex since insertion/removal happens concurrently.

Definition at line 78 of file rtt_rostopic_ros_publish_activity.hpp.

Reimplemented from RTT::base::ActivityInterface.

Member Function Documentation

Definition at line 62 of file rtt_rostopic_ros_publish_activity.cpp.

Returns the single instance of the RosPublisher. This function is not thread-safe when it creates the RosPublisher object. Therefor, it is advised to cache the object which Intance() returns such that, in the unlikely event that two publishers exist, you consistently keep using the same instance, which is fine then.
