Description

  int $index,
): array<string, mixed>

Parameters

  • int$index - The edge index

Return Values

  • array<string, - mixed> The requested edge, with these fields:

index the edge id == $index kind Counted, Implicit, or Ambiguous from node id owning the pointer to node id of the node pointed to

If the from node is an array: key num; this pointer is the num'th key in iterator order (0..) value num; pointer is the num'th value in iter order
