ArangoDBClient\GraphHandler\saveEdge PHPDoc Issue

[mstrofbass]

I might be misunderstanding or missing something...so preemptively sorry.

The PHPdoc for ArangoDBClient\GraphHandler\saveEdge states that:

@param string $collection - if one uses a graph with more than one vertex collection one must provide the collection

I believe that "vertex" should be "edge", specifically because it initially confused me then I saw that the associated code is:

    if ($collection === null) {
        $edgeCollections      = $this->getEdgeCollections($graph);
        $edgeCollectionsCount = count($edgeCollections);
        if ($edgeCollectionsCount !== 1) {
            throw new ClientException('A collection must be provided.');
        }

        if ($edgeCollectionsCount === 1) {
            $collection = $edgeCollections[0];
        }
    }
