Detailed Description
template<typename T = Any>
class BT::LoopNode< T >
The LoopNode class is used to pop_front elements from a std::deque. This element is copied into the port "value" and the child will be executed, as long as we have elements in the queue.
See Example 4: ex04_waypoints
NOTE: unless T is Any, string or double, you must register the loop manually into the factory.
