Class Detail
orion.core.ContentTypeRegistry(dataSource)
A registry that provides information about orion.core.ContentTypes.
If a orion.serviceregistry.ServiceRegistry is available, clients should request the service with
objectClass "orion.core.contentTypeRegistry" from the registry rather than instantiate this
class directly. This constructor is intended for use only by page initialization code.
- Parameters:
- {orion.serviceregistry.ServiceRegistry|orion.core.ContentType[]} dataSource
- The service registry
to use for looking up available content types and for registering this ContentTypeRegistry.
Alternatively, an array of ContentType data may be passed instead, which allows clients to use this ContentTypeRegistry without a service registry.
