tf2 is the second generation of the tf library. This is a library originally shipped with ROS (Robot Operating System), and its original version can be found in //third_party/ros/tf2. This new version ports the main functionality into a library that does not depend on ROS nor on Boost, and instead uses code from Abseil, Eigenmath and Genit.
This library implements the interface defined by eigenmath::tf2::BufferCore.
The main interface is through the eigenmath::tf2::BufferCore interface.
It uses the statuses from //absl/status, the time-stamps from //absl/time, and the transforms types from //eigenmath.
