Method Detail

getServiceInfo

public final <R> R getServiceInfo(ServiceParameterBuffer serviceParameterBuffer,
                                  ServiceRequestBuffer serviceRequestBuffer,
                                  int bufferLength,
                                  InfoProcessor<R> infoProcessor)
                           throws java.sql.SQLException

Description copied from interface: FbService

Request service info (service query).

Specified by:

getServiceInfo in interface FbService

Parameters:

serviceParameterBuffer - Service parameters

serviceRequestBuffer - Service request info

bufferLength - Response buffer length to use

infoProcessor - Implementation of InfoProcessor to transform the info response

Returns:

Transformed info response of type T

Throws:

java.sql.SQLException - For errors retrieving or transforming the response.

addServiceListener

public final void addServiceListener(ServiceListener listener)

Description copied from interface: FbService

Adds a ServiceListener instance to this database.

Specified by:

addServiceListener in interface FbService

Parameters:

listener - Database listener

removeServiceListener

public final void removeServiceListener(ServiceListener listener)

Description copied from interface: FbService

Removes a ServiceListener instance from this database.

Specified by:

removeServiceListener in interface FbService

Parameters:

listener - Database Listener

internalDetach

protected abstract void internalDetach()
                                throws java.sql.SQLException

Actual implementation of service detach.

Implementations of this method should only be called from close(), and should not notify service listeners of the service ServiceListener.detaching(FbService) and ServiceListener.detached(FbService) events.

Throws:

java.sql.SQLException

close

public final void close()
                 throws java.sql.SQLException

Detaches and closes the connection.

Implementation note: Calls AbstractFbAttachment.checkConnected() and notifies service listeners of the detaching event, then calls internalDetach() and finally notifies service listeners of database detach and removes all listeners.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface FbAttachment

Throws:

java.sql.SQLException - If not currently connected, or another problem occurred detaching.

getServiceWarningCallback

protected final WarningMessageCallback getServiceWarningCallback()

Returns:

The warning callback for this service.

getDescribeServiceRequestBuffer

protected ServiceRequestBuffer getDescribeServiceRequestBuffer()

getServiceInformationProcessor

protected InfoProcessor<FbService> getServiceInformationProcessor()
