Detailed Description

template<class M, typename ::std::enable_if_t< ros::message_traits::HasHeader< M >::value > * = nullptr>
class cras::TfMessageFilter< M, >

Follows the patterns set by the message_filters package to implement a filter which only passes messages through once there is transform data available.

The callbacks used in this class are of the same form as those used by roscpp's message callbacks.

MessageFilter is templated on a message type.

Example Usage

If you want to hook a MessageFilter into a ROS topic:

message_filters::Subscriber<MessageType> sub(node_handle_, "topic", 10);
cras::TFMessageFilter<MessageType> tf_filter(log, sub, tf_buffer_, "/map", 10, 0);
tf_filter.registerCallback(&MyClass::myCallback, this);
