Method Detail

isConfigurationAcceptable

public boolean isConfigurationAcceptable(JeBackendCfg cfg,
                                         List<LocalizableMessage> unacceptableReasons,
                                         ServerContext serverContext)

Description copied from class: Backend

Indicates whether the provided configuration is acceptable for this backend. It should be possible to call this method on an uninitialized backend instance in order to determine whether the backend would be able to use the provided configuration.

Overrides:

isConfigurationAcceptable in class BackendImpl<JeBackendCfg>

Parameters:

cfg - The backend configuration for which to make the determination.

unacceptableReasons - A list that may be used to hold the reasons that the provided configuration is not acceptable.

serverContext - this Directory Server instance's server context

Returns:

true if the provided configuration is acceptable for this backend, or false if not.

configureStorage

protected Storage configureStorage(JeBackendCfg cfg,
                                   ServerContext serverContext)
                            throws ConfigException

Description copied from class: BackendImpl

Creates the storage engine which will be used by this pluggable backend. Implementations should create and configure a new storage engine but not open it.

Specified by:

configureStorage in class BackendImpl<JeBackendCfg>

Parameters:

cfg - the configuration object

serverContext - this Directory Server intsance's server context

Returns:

The storage engine to be used by this pluggable backend.

Throws:

ConfigException - If there is an error in the configuration.

getLocalBackendMonitor

protected PluggableBackendMonitor getLocalBackendMonitor()

Description copied from class: LocalBackend

Returns the local backend monitor associated with this backend.

Implementations may override this method in order to provide custom implementations.

Specified by:

getLocalBackendMonitor in class BackendImpl<JeBackendCfg>

Returns:

The local backend monitor associated with this backend.
