EdgesDeleteTrait uses trait:short, trait:short, trait:short

Provides deletion utilities for ArangoDB edge collections.

This trait simplifies deleting edge documents by:

Handling vertex ID resolution (_from and _to) automatically.
Constructing dynamic AQL queries with optional filter conditions.
Supporting deletion of single edges, edges from a specific vertex, edges to a specific vertex, or all edges connected to a vertex.

It is intended to be used with models extending Documents and leveraging:

DocumentsDeleteTrait for generic document deletion logic.
EdgesExistTrait to optionally check for existing edges (e.g., uniqueness enforcement).
VerticesTrait for vertexID() helper and $from / $to model contexts.
ArangoTrait for executing ArangoDB queries.

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).

bindCollection() : string: Bind a collection name to an AQL query variable.
bindView() : string: Bind the model's declared View name (`AQL::VIEW` block, {@see Search::NAME}) to an AQL query variable — collection bind parameters (`@@view`) are valid for View names as well.
collectionCreate() : bool: Creates a new collection if not exist.
collectionDrop() : bool: Drops a collection if exist.
collectionExists() : bool: Check if collection exists
collectionRename() : bool: Renames a collection if exist.
