getLinksInFixedJointKinematicTree()

TESSERACT_COMMON_IGNORE_WARNINGS_PUSH TESSERACT_COMMON_IGNORE_WARNINGS_POP std::vector< std::string > getLinksInFixedJointKinematicTree	(	const std::string &	input_link,
		const tesseract::scene_graph::SceneGraph &	scene_graph
	)

Returns the names of the links that comprise a fixed-joint kinematic tree with the input link.

This method first traverses from the input link "up" the scene graph hierarchy, following the link's in-bound joints, to find the input link's highest level parents that are connected to it by fixed joints. Next, it identifies all the fixed-joint children of these highest level parent links. Together, the highest level parent links and their fixed-joint children comprise a set of links (including the input link), between all of which exists a tree of fixed joints. If the link does not have any fixed-joint parents, the name of the link itself will be returned.
