InMemory Metadata Provider

The in-memory provider returns metadata objects with intermediate caching of types in RAM.

To create an in-memory provider you should create a new InMemoryProvider instance, parent another provider (or metadata reader) in the constructor.

use TypeLang\Mapper\Mapper;
use TypeLang\Mapper\Platform\StandardPlatform;
use TypeLang\Mapper\Mapping\Provider\InMemoryProvider;

$provider = new InMemoryProvider(
    delegate: new AnotherMetadataProvider(),
);

$mapper = new Mapper(
    [[[platform: new StandardPlatform(|standard-platform.html]]]
        meta: $provider,
        // ...
    ),
);
