IMetaContext (server-common-api)

All Superinterfaces:

IComponent, IComponentProvider, IInitializable, IURIResolver
```
public interface IMetaContext
extends IComponentProvider
```
The meta context provides the various meta services for a given datasource. Each meta context is a singleton for the given datasource, therefore you can use ==, although Object.equals(java.lang.Object) is supported. This is a component as well as a component provider. Not all services are documented since some are internal system services and not for public use, and may not be supported in future versions.

PortalSystem.getMetaProvider(), IMetaManager, IPhaseProvider
