Member Function Documentation

◆ onHalted()

void BT::SleepNode::onHalted ( )

overridevirtual

when the method halt() is called and the action is RUNNING, this method is invoked. This is a convenient place todo a cleanup, if needed.

Implements BT::StatefulActionNode.

◆ onRunning()

NodeStatus BT::SleepNode::onRunning ( )

overridevirtual

method invoked when the action is already in the RUNNING state.

Implements BT::StatefulActionNode.

◆ onStart()

NodeStatus BT::SleepNode::onStart ( )

overridevirtual

Method called once, when transitioning from the state IDLE. If it returns RUNNING, this becomes an asynchronous node.

Implements BT::StatefulActionNode.

The documentation for this class was generated from the following file:
