DatabaseMonitor

public DatabaseMonitor()

Deprecated, for removal: This API element is subject to removal in a future version.

Method Details

isConnected

public static boolean isConnected()

Deprecated, for removal: This API element is subject to removal in a future version.

Checks whether the last known status of the database connection is connected. A check is run in a fixed interval. Use testConnection() to run a check now.

Returns:

true if the database connection is connected, false otherwise.

check

public boolean check()

Deprecated, for removal: This API element is subject to removal in a future version.

Checks whether the database connection is healthy, i.e. whether the database is reachable.

Returns:

true if the database connection is healthy, false otherwise.

testConnection

public static boolean testConnection()

Deprecated, for removal: This API element is subject to removal in a future version.

Checks whether the database connection is healthy, i.e. whether the database is reachable. In contrast with isConnected(), this method actually performs a check and tries to reach the database, instead of returning the current status.

Returns:

true if the database connection is healthy, false otherwise.

registerConnectionEstablishedListener

public static void registerConnectionEstablishedListener(IBaseNotificationListener listener)

Deprecated, for removal: This API element is subject to removal in a future version.

registerDisconnectedListener

public static void registerDisconnectedListener(IBaseNotificationListener listener)

Deprecated, for removal: This API element is subject to removal in a future version.

registerReconnectedListener
