getReader

public IStoreAccessor getReader(ISession session)
Description copied from interface: IStore
Returns a reader that can be used to read from this store in the context of the given session.

Specified by:
getReader in interface IStore
Parameters:
session - The session that should be used as a context for read access or null. The store implementor is free to interpret and use the session in a manner suitable for him or ignore it at all. It is meant only as a hint. Implementor can use it as a key into a cache and/or register a LifecycleEventAdapter with it to intercept cleanup on session close. Note however that the session can be null, for example during startup of the server while the repositories are initialized but before any user session has been opened.
Returns:
a reader that can be used to read from this store in the context of the given session, never null.

getWriter

public IStoreAccessor getWriter(ITransaction transaction)
Description copied from interface: IStore
Returns a writer that can be used to write to this store in the context of the given view. The given view is always marked as a transaction.

Specified by:
getWriter in interface IStore
Parameters:
transaction - The view that must be used as a context for write access. The store implementor is free to interpret and use the view in a manner suitable for him or ignore it at all. It is meant only as a hint. Implementor can use it as a key into a cache and/or register a LifecycleEventAdapter with it to intercept cleanup on view close.
Returns:
a writer that can be used to write to this store in the context of the given view, never null.

getIndicatingCommitDistributor

public ProgressDistributor getIndicatingCommitDistributor()
Specified by:

createRevision

public InternalCDORevision createRevision(EClass eClass,
                                          CDOID id)
Since:
3.0

releaseAccessor

protected void releaseAccessor(StoreAccessorBase accessor)
Since:
4.0

getReaderPool

protected abstract StoreAccessorPool getReaderPool(ISession session,
                                                   boolean forReleasing)
Returns a pool that may contain IStoreAccessor instances that are compatible with the given session. The implementor may return null to indicate that no pooling occurs. It's also left to the implementors choice how to determine the appropriate pool instance to be used for the given session, for example it could always return the same pool instance, regardless of the given session.

If the implementor of this method decides to create pools that are only compatible with certain sessions or views, then it is his responsibility to listen to REMOVED events sent by either the ISessionManager (indicating that a session is closed) or any of its sessions (indicating that a view is closed). Note: Closing a session implies that all contained views are closed sliently without firing respective events!

Parameters:
session - The context which the pool must be compatible with. Must not be null.
forReleasing - Enables lazy pool creation. The implementor is not supposed to create a new pool if false is passed. If true is passed it's up to the implementor whether to create a new pool or not.

getWriterPool

protected abstract StoreAccessorPool getWriterPool(IView view,
                                                   boolean forReleasing)
Returns a pool that may contain IStoreAccessor instances that are compatible with the given session. The implementor may return null to indicate that no pooling occurs. It's also left to the implementors choice how to determine the appropriate pool instance to be used for the given session, for example it could always return the same pool instance, regardless of the given session.

If the implementor of this method decides to create pools that are only compatible with certain sessions or views, then it is his responsibility to listen to REMOVED events sent by either the ISessionManager (indicating that a session is closed) or any of its sessions (indicating that a view is closed). Note: Closing a session implies that all contained views are closed sliently without firing respective events!

Parameters:
view - The context which the pool must be compatible with. Must not be null.
forReleasing - Enables lazy pool creation. The implementor is not supposed to create a new pool if false is passed. If true is passed it's up to the implementor whether to create a new pool or not.

Creates and returns a new IStoreAccessor instance. The caller of this method is responsible for activating the new instance.
