SchemaHandle::find_metadata │ public │ WC 1.0

Filter-narrows view over {@see self::get_all_metadata()}.

Each filter argument independently restricts the result set; supplying multiple composes as AND. When $name is supplied, the surviving rows have their entries trimmed to the single matching entry; so a caller asking "which elements are marked X" gets focused rows back, not the full multi-entry shape.

Method of the class: SchemaHandle{}

No Hooks.

Returns

list. string, field: ?string, argument: ?string, enumValue: ?string, entries: array<string, bool|int|float|string|null>, authorization: list<array{attribute: string, args: list<mixed>}>}>

?string $name
