To help to do that, library only provide serialization of objects and restoration of inheritance between objects.

Schema

Description of classes represents the a schema.

Hector\Schema\SchemaContainer

It's a container of schema. Methods available:

• SchemaContainer::getSchemas(?string $connection = null): Generator Returns a generator of Hector\Schema\Schema objects, you can pass a specific connection
• SchemaContainer::hasSchema(string $name, ?string $connection = null): bool Check if container has a schema
