getNodesByPath()

template<typename NodeType = BT::TreeNode>

std::vector<const TreeNode*> BT::Tree::getNodesByPath ( StringView  wildcard_filter ) const

inline

Get a list of nodes which fullPath() match a wildcard filter and a given path. Example:

move_nodes = tree.getNodesByPath<MoveBaseNode>("move_*");

sleep()

bool BT::Tree::sleep

(

std::chrono::system_clock::duration

timeout

)

Sleep for a certain amount of time. This sleep could be interrupted by the method TreeNode::emitWakeUpSignal()

Parameters

timeout

duration of the sleep

Returns

true if the timeout was NOT reached and the signal was received.

Definition at line 565 of file bt_factory.cpp.

tickExactlyOnce()

NodeStatus BT::Tree::tickExactlyOnce

(

)

Tick the root of the tree once, even if a node invoked emitWakeUpSignal()

Definition at line 576 of file bt_factory.cpp.

tickOnce()

NodeStatus BT::Tree::tickOnce

(

)

by default, tickOnce() sends a single tick, BUT as long as there is at least one node of the tree invoking TreeNode::emitWakeUpSignal(), it will be ticked again.

Definition at line 581 of file bt_factory.cpp.

tickRoot()

NodeStatus BT::Tree::tickRoot ( TickOption  opt, std::chrono::milliseconds  sleep_time  )

private

Definition at line 616 of file bt_factory.cpp.

tickWhileRunning()

NodeStatus BT::Tree::tickWhileRunning

(

std::chrono::milliseconds

sleep_time = std::chrono::milliseconds(10)

)

Call tickOnce until the status is different from RUNNING. Note that between one tick and the following one, a Tree::sleep() is used
