Collections

Lodata implements Collections (opens new window) of primitive and complex types.

Collections are defined through the Type::collection() definition. The underlying type is Edm.Untyped by default, allowing any primitive or complex entries. To set a more specific underlying type, the type definition can be supplied as an argument to Type::collection().

$person = (new EntityType( 'person' ))
  ->addDeclaredProperty( 'name', Type::string() );
  ->addDeclaredProperty( 'emails', Type::collection() );
  ->addDeclaredProperty( 'scores', Type::collection(Type::decimal()) );

Collection instances implement the Arrayable interface, so they can be easily built at runtime in singletons or operations.
