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).

initializeIndexes()

Sets the declared indexes of the collection from the init definition, normalizing a single {@see IndexOptions} value to a one-element list (a raw array always stays the index list) — so every consumer sees a plain `IndexOptions[]`: the {@see initializeCollection()} lazy provisioning and the {@see DoctorTrait} diagnose/repair diffs.


    public
                    initializeIndexes([array<string|int, mixed> $init = [] ]) : static

Parameters

$init : array<string|int, mixed> = []

Return values

prepareAndExecute()

Prepare and execute an ArangoDB AQL query.


    public
                    prepareAndExecute(string $query[, array<string|int, mixed> $bindVars = [] ][, array<string|int, mixed> $options = [] ][, array<string|int, mixed>|null $optionalBinds = null ]) : static

A bind variable may be optional : supplied by the caller (through Arango::BINDS) yet not guaranteed to appear in the final query text. This happens with a conditional projection — e.g. an aqlBindRef() inside a Field::WHERE / Field::WHEN carried by a field that the active skin (or an explicit ?fields) does not project. ArangoDB rejects a query that declares a bind it never references ("bind parameter 'x' was not declared in the query"), so such a leftover bind must be dropped before execution.

$optionalBinds names the binds that are allowed to be absent :

it is opt-in and bounded — a bind whose name is not listed is never touched, so a query that uses no conditional bind behaves exactly as before ;
a listed bind is kept only when the query actually references it (@name, word-boundary matched to avoid a prefix collision such as @offers matching inside @offersScope) ;
passing [] disables the pruning explicitly.

When $optionalBinds is null (the default), the list is derived from the model's own declarations — every AqlBindReference found anywhere in $this->fields / $this->skinFields and in the relation registries $this->edges / $this->joins (see collectOptionalBindNames()). The registries matter as much as the projections: a relation definition is a declaration tree of its own, it can carry a conditional bind (in its own AQL::FIELDS sub-projection, or in a definition-level predicate), and a skin dropping the relation leaves that bind unreferenced exactly the same way. The source of truth is the same aqlBindRef() that declared the conditional bind, so no host wiring is required, and over-listing a bind that turns out to be always present is inert (a referenced bind is always kept). Because this runs at the single execution chokepoint, it protects every query method (get(), list(), count(), exist(), edges…) uniformly.

Parameters

$query : string: The AQL query string to execute.
$bindVars : array<string|int, mixed> = []: Optional bind variables for the query.
$options : array<string|int, mixed> = []: Optional execution options.
$optionalBinds : array<string|int, mixed>|null = null: Names of binds allowed to be absent from the query. null derives the list from the model field definitions and relation registries ; [] disables the pruning.

Return values

static

$raw : bool = false: If true, returns the object raw (no schema or alter applied)
$schema : null|SchemaResolver|Closure|string = null: The optional class name to map the document.
$context : array<string|int, mixed> = []: Optional opaque context forwarded to AlterDocumentTrait::alter() and thus to the Alter::MAP callbacks (e.g. the originating $init, a skin, a locale…). Default [].

Return values

Generator<string|int, mixed> —

Generator yielding documents one by one

viewCreate()

Creates an `arangosearch` View if it does not already exist.


    public
                    viewCreate(string $name[, array<string|int, mixed> $links = [] ][, array<string|int, mixed> $options = [] ]) : bool

Parameters

$name : string: The name of the new View.
$links : array<string|int, mixed> = []: Per-collection link map (collection name → link definition).
$options : array<string|int, mixed> = []: Extra arangosearch options forwarded verbatim.

Return values

bool —

Returns true if the new View has been created.

viewExists()

Checks if a View exists.


    public
                    viewExists(string $name) : bool

Parameters

$name : string: The name of the View.

Return values

bool

firstRowAsArray()

Runs a single-row aggregate query and normalizes its result to an array.


    protected
                    firstRowAsArray(string $query[, array<string|int, mixed> $bindVars = [] ]) : array<string|int, mixed>

The aggregate queries — DocumentsBoundsTrait::bounds(), DocumentsFacetCountsTrait::facetCounts() — all return one row holding one entry per requested dimension, and all face the same two shapes: their builder yields an empty string when nothing is computable, and the row itself comes back as an object or as an array depending on how the driver decoded it. Both are handled here rather than at each call site.

The result is read raw — no schema, no alter() — because the row is a map of computed values, not a document.

Parameters

$query : string: The compiled aggregate query, or an empty string when there is nothing to compute.
$bindVars : array<string|int, mixed> = []: The bind variables of that query.

Return values

array<string|int, mixed> —

The single row as an associative array; an empty array when the query is empty or the row is neither an object nor an array.

profileOptions()

Merges the cursor `profile` option into `$options` when the `$init` array requests profiling via {@see Arango::PROFILE} (`true` → profile level 2, or an explicit integer level). Returns `$options` unchanged otherwise.


    protected
                    profileOptions(array<string|int, mixed> $init[, array<string|int, mixed> $options = [] ]) : array<string|int, mixed>

Parameters

$init : array<string|int, mixed>: The model input array (list() / get()).
$options : array<string|int, mixed> = []: The cursor options to augment.

Return values

array<string|int, mixed>

collectOptionalBindNames()

Collects every {@see AqlBindReference} name declared anywhere in one or more declaration trees — the projections (`$fields` / `$skinFields`) **and** the relation registries (`$edges` / `$joins`), typically inside a `Field::WHERE` / `Field::WHEN` condition. These are the *optional* binds : a skin (or an explicit `?fields`) can drop the carrying field — or the whole relation — from the projection, so the declared bind may not reach the final query text.


    private
                    collectOptionalBindNames(array<string|int, mixed> ...$trees) : array<int, string>

The walk is recursive and depth-agnostic : it descends into Field::FIELDS, edges and joins sub-definitions, and picks up a bind reference wherever it sits. Non-array leaves are visited but ignored, so a registry holding a resolved model instance or a callable is harmless. Collecting the raw (un-skinned) definitions is intentional — the superset of all possibly-optional binds is exactly what the execution layer must be allowed to prune.

Parameters

$trees : array<string|int, mixed>: One or more declaration arrays to scan.

Return values

array<int, string> —

The de-duplicated list of bind names.
