Public Member Functions
	PopFromQueue (const std::string &name, const NodeConfig &config)
NodeStatus	tick () override
	Method to be implemented by the user.
Public Member Functions inherited from BT::SyncActionNode
	SyncActionNode (const std::string &name, const NodeConfig &config)
	SyncActionNode (const SyncActionNode &)=delete
SyncActionNode &	operator= (const SyncActionNode &)=delete
	SyncActionNode (SyncActionNode &&)=delete
SyncActionNode &	operator= (SyncActionNode &&)=delete
virtual NodeStatus	executeTick () override
	throws if the derived class return RUNNING.
virtual void	halt () override final
	You don't need to override this.
Public Member Functions inherited from BT::ActionNodeBase
	ActionNodeBase (const std::string &name, const NodeConfig &config)
	ActionNodeBase (const ActionNodeBase &)=delete
ActionNodeBase &	operator= (const ActionNodeBase &)=delete
	ActionNodeBase (ActionNodeBase &&)=delete
ActionNodeBase &	operator= (ActionNodeBase &&)=delete
virtual NodeType	type () const override final
Public Member Functions inherited from BT::LeafNode
	LeafNode (const std::string &name, const NodeConfig &config)
	LeafNode (const LeafNode &)=delete
LeafNode &	operator= (const LeafNode &)=delete
	LeafNode (LeafNode &&)=delete
LeafNode &	operator= (LeafNode &&)=delete
Public Member Functions inherited from BT::TreeNode
	TreeNode (std::string name, NodeConfig config)
	TreeNode main constructor.
	TreeNode (const TreeNode &other)=delete
TreeNode &	operator= (const TreeNode &other)=delete
	TreeNode (TreeNode &&other) noexcept
TreeNode &	operator= (TreeNode &&other) noexcept
virtual BT::NodeStatus	executeTick ()
	The method that should be used to invoke tick() and setStatus();.
void	haltNode ()
bool	isHalted () const
NodeStatus	status () const
const std::string &	name () const
	Name of the instance, not the type.
BT::NodeStatus	waitValidStatus ()
virtual NodeType	type () const =0
StatusChangeSubscriber	subscribeToStatusChange (StatusChangeCallback callback)
	subscribeToStatusChange is used to attach a callback to a status change. When StatusChangeSubscriber goes out of scope (it is a shared_ptr) the callback is unsubscribed automatically.
void	setPreTickFunction (PreTickCallback callback)
void	setPostTickFunction (PostTickCallback callback)
void	setTickMonitorCallback (TickMonitorCallback callback)
uint16_t	UID () const
const std::string &	fullPath () const
const std::string &	registrationName () const
	registrationName is the ID used by BehaviorTreeFactory to create an instance.
const NodeConfig &	config () const
template<typename T >
Result	getInput (const std::string &key, T &destination) const
template<typename T >
Expected< Timestamp >	getInputStamped (const std::string &key, T &destination) const
	getInputStamped is similar to getInput(dey, destination), but it returns also the Timestamp object, that can be used to check if a value was updated and when.
template<typename T >
Expected< T >	getInput (const std::string &key) const
template<typename T >
Expected< StampedValue< T > >	getInputStamped (const std::string &key) const
template<typename T >
Result	setOutput (const std::string &key, const T &value)
	setOutput modifies the content of an Output port
AnyPtrLocked	getLockedPortContent (const std::string &key)
	getLockedPortContent should be used when:
StringView	getRawPortValue (const std::string &key) const
void	emitWakeUpSignal ()
	Notify that the tree should be ticked again()
bool	requiresWakeUp () const

	Check a string and return true if it matches the pattern: {...}.

	Method to be implemented by the user.
void	resetStatus ()
	Set the status to IDLE.
void	setRegistrationID (StringView ID)
void	setWakeUpInstance (std::shared_ptr< WakeUpSignal > instance)
void	modifyPortsRemapping (const PortsRemapping &new_remapping)
void	setStatus (NodeStatus new_status)
	setStatus changes the status of the node. it will throw if you try to change the status to IDLE, because your parent node should do that, not the user!
