Gliph\Graph\MutableVertexSet::ensureVertex PHP 메소드

Gliph requires that its graph vertices be objects; beyond that, it does not care about vertex type.

public ensureVertex ( object $vertex ) : Gliph\Graph\Graph
$vertex	object	An object to use as a vertex in the graph.
리턴	Gliph\Graph\Graph	The current graph instance.

    public function ensureVertex($vertex);
