PrepareTraversalTrait uses trait:short, \oihana\models\traits\BindsTrait, trait:short

Trait providing utility to prepare vertex traversal queries in ArangoDB.

This trait standardizes the preparation of traversal parameters, vertex IDs, bind variables, filters, and edge/graph references for use in AQL queries.

It is designed to be mixed into edge collection models and can be used in conjunction with ArangoTrait and BindsTrait.

Properties

$collection : string|null: The default collection name.
$indexes : array<string|int, mixed>|null: The declared indexes of the collection (the `AQL::INDEXES` list of {@see IndexOptions} or raw definitions). Retained at initialization — whether the lazy provisioning ran or not — so the declaration can be compared with the server later ({@see DoctorTrait::diagnose()}).
$arangodb : ArangoDB|null: The ArangoDB database reference.
$type : int: Indicates the type of the collection when is created (document or edge).

Methods

analyzerExists() : bool: Checks if an analyzer exists on the server (built-in analyzers are always reported).
collectionCreate() : bool: Creates a new collection if not exist.
collectionDrop() : bool: Drops a collection if exist.
collectionExists() : bool: Check if collection exists

explain() : ExplainResult: Explains an AQL query — returns the optimizer's execution plan as a typed {@see ExplainResult} (rules applied, collections, estimated cost, indexes actually used) **without executing the query**.
foundRows() : int: For a SELECT with a LIMIT clause, returns the number of rows that would be returned were there no LIMIT clause.
getDatabase() : ArangoDB: Returns the ArangoDB database singleton reference.
getDocuments() : array<string|int, mixed>: Prepare, execute and returns an array of all documents with the passed-in AQL query.

prepareTraversalWith()

Derives the AQL `WITH` clause declaring the vertex collections reached by an **anonymous** traversal (edge collection, no named graph).


    private
                    prepareTraversalWith(string $direction[, Documents|null $from = null ][, Documents|null $to = null ][, array<string|int, mixed> $init = [] ]) : string

In a cluster, collections accessed dynamically by collection-set traversals must be declared up front so they are all locked at query start, which avoids deadlocks. Named-graph traversals already know their collections, so this returns an empty string for them. The clause is harmless (a no-op) on a single server.

Declared collections, by direction:

Traversal::OUTBOUND → the $to vertex collection,
Traversal::INBOUND → the $from vertex collection,
Traversal::ANY → both $from and $to (de-duplicated).

An explicit AQL::WITH entry in $init (a collection name or an array of names) overrides the direction-based derivation.

Parameters

$direction : string: Traversal direction (Traversal).
$from : Documents|null = null: The _from vertex model (may be null).
$to : Documents|null = null: The _to vertex model (may be null).
$init : array<string|int, mixed> = []: The traversal init array (read-only here).

Return values

string —

The WITH coll1, coll2, ... clause, or an empty string when there is nothing to declare (named graph, missing models, or explicit empty).
