How can I find out the detailed API of messages?

Point, I can only find the definition here http://www.ros.org/doc/api/geometry_m... . However, there are many methods such as push_back and so on which are not mention in ros-wiki or ros-api. I think ros must have been befined some iterators and containers. So where are the document of API or source code?

Any suggestion would be appreciate. Best regards!

Message generation uses standard C++/Boost data types and containers when creating messages for C++. Variable size arrays are represented by std::vector, fixed size arrays are represented by boost:array. For more information on how to use these, please have a look at your favorite C++ API reference and the boost documentation.

You can find a complete list of data type mappings used in message generation here.

I attempt to use Point.pop(), the compiler give me an error. ERROR: 'class std::vector<geometry_msgs::point_<std::allocator<void>>, std::allocator<geometry_msgs::point_<std::allocator<void>>>' has no member named 'pop'.

In this case, Point as a datatype in container std::vector.

So, there must be some mechanism to encapsulate the datatype in ROS such as visualization_msgs::Marker. Where are they?

There is no pop() function in vector, only pop_back(). Here is a documentation of the vector class: http://en.cppreference.com/w/cpp/container/vector.

That's right. Thanks.
