SchemaHandle::get_all_metadata │ public │ WC 1.0

Return every metadata row in the schema (introspection types excluded).

Each row describes one target (a type, a field, an argument, or an enum value) and carries the name=>value entries declared on it. The same row shape is used for every target kind; the three nullable position fields (field, argument, enumValue) discriminate.

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>}>}>

Usage

$SchemaHandle = new SchemaHandle();
$SchemaHandle->get_all_metadata(): array;
