DocumentsFacetCountsTrait uses trait:short, trait:short
Computes per-value **facet counts** for several dimensions at once, returned alongside (not replacing) the document list.
The dimensions are facet keys from Arango::FACETS; the buckets are counted
over the same conjunctive filter as list(). See
FacetCountsQueryTrait for the generated AQL.

ExplainResultfacetCount()
Flattens one dimension's facet buckets into a `value => count` map.
public
facetCount(string $dimension[, array<string|int, mixed> $init = [] ]) : array<string, int>
A thin projection over DocumentsFacetCountsTrait::facetCounts() for
the common "count by <dimension>" need: instead of the multi-dimension
[ { value, count }, ... ] bucket lists, it returns a single flat map for
one dimension, preserving the buckets' count-descending order. Malformed
rows (missing value) are skipped and each count is cast to int.
The dimension must be a declared facet (Arango::FACETS); an unknown
key produces an empty map (nothing is countable). The sum of the returned
counts equals the number of matching documents for a scalar facet; for
a multi-valued (array-membership) facet a document contributes to several
buckets, so the sum over-counts — pair DocumentsFacetCountsTrait::facetCounts()
with a dedicated count() when an exact total is needed in that case.
Parameters
- $dimension : string
-
The facet key to count.
- $init : array<string|int, mixed> = []
-
The filtered-set options (same keys as DocumentsFacetCountsTrait::facetCounts()).
Tags
Return values
array<string, int> —A value => count map (empty when nothing countable).

Arango::FACET_COUNTSholds the facet keys to count; the other keys (active,facets,filter,search,conditions) define the filtered set.

Return values
staticprepareAndExecute()
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@offersmatching 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> = []

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

Parameters
- $name : string
-

- $links : array<string|int, mixed> = []
-
Per-collection link map (collection name → link definition).
- $options : array<string|int, mixed> = []

bool —Returns true if the new View has been created.

boolfirstRowAsArray()
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.
Tags
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()

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

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

The facet definition (
Facet::TYPE,Facet::PROPERTY). - $key : string
-

The shared
FILTERclause. - $docRef : string

Return values
string|nullcollectOptionalBindNames()
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.
facetCountCollect()

private
facetCountCollect(string $expression, string $sort[, string|null $distinctKey = null ]) : array{0: string, 1: string, 2: string}
By default the bucket count is the number of unwound rows
(WITH COUNT INTO count). When $distinctKey is provided (opt-in
Facet::DISTINCT => true on an unwinding facet), the count becomes the
number of DISTINCT root documents in the bucket
(AGGREGATE count = COUNT_DISTINCT( <distinctKey> )), so a document whose
array repeats the same sub-field value is counted once — matching the
?filter= existence semantics. The aggregate is deliberately named
Group::COUNT_NAME (count) so the derived RETURN { value, count }
and the SORT count DESC clause stay identical in both modes.
Parameters
- $expression : string
-
The value expression to group on.
- $sort : string
-
The pre-built
SORT count DESCclause. - $distinctKey : string|null = null
-
The root document key expression to count distinctly (e.g.
doc._key), or null for the default per-element count.
