org.eclipse.orion.server.core.metastore.IMetaStore
The metadata store is responsible for persisting Orion user and workspace metadata. The key design characteristics are:
- Each operation on this interface is atomic, it will either completely succeed or completely fail and make no backing change.
- The store can change in arbitrary ways between any two method invocations. Other threads or other processes can alter the backing store before or after each interaction.
@noimplement This is not intended to be implemented by clients. Backing store implementationswill implement this interface, but must expect breaking changes to occur between releases.
