mbf_abstract_nav::AbstractPlannerExecution Class Reference

The AbstractPlannerExecution class loads and binds the global planner plugin. It contains a thread running the plugin in a cycle to plan and re-plan. An internal state is saved and will be pulled by the server, which controls the global planner execution. Due to a state change it wakes up all threads connected to the condition variable. More...
