Gliph\Graph\Digraph::arcsFrom PHP Method

arcsFrom() public method

An arc is outbound from a vertex if that vertex is the 'tail' of the arc. Returns a generator that yields 2-tuple (array) where the first two values represent the vertex pair. Vertex order is guaranteed: the first vertex is the tail, and the second vertex is the head. If the graph has additional edge data (e.g., weight), additional elements are appended to the edge array as needed. (See implementation-specific documentation for more detail).

public arcsFrom ( $vertex ) : Generator
$vertex		The vertex whose out-arcs should be visited.
return	Generator	A generator that yields out-arcs as values.
