public class MariaDbPooledConnection extends Object implements PooledConnection

  • Field Details

  • Constructor Details

    • MariaDbPooledConnection

      public MariaDbPooledConnection(MariaDbConnection connection)
      Constructor.
      Parameters:
      connection - connection to retrieve connection options

  • Method Details

    • getConnection

      public MariaDbConnection getConnection()
      Creates and returns a Connection object that is a handle for the physical connection that this PooledConnection object represents. The connection pool manager calls this method when an application has called the method DataSource.getConnection and there are no PooledConnection objects available. See the interface description for more information.
      Specified by:
      getConnection in interface PooledConnection
      Returns:
      a Connection object that is a handle to this PooledConnection object

    • close

      public void close() throws SQLException
      Closes the physical connection that this PooledConnection object represents. An application never calls this method directly; it is called by the connection pool module, or manager.
      See the interface description for more information.
      Specified by:
      close in interface PooledConnection
      Throws:
      SQLException - if a database access error occurs

    • abort

      public void abort(Executor executor) throws SQLException
      Abort connection.
      Parameters:
      executor - executor
      Throws:
      SQLException - if a database access error occurs

    • addConnectionEventListener

      public void addConnectionEventListener(ConnectionEventListener listener)
      Registers the given event failover so that it will be notified when an event occurs on this PooledConnection object.
      Specified by:
      addConnectionEventListener in interface PooledConnection
      Parameters:
      listener - a component, usually the connection pool manager, that has implemented the ConnectionEventListener interface and wants to be notified when the connection is closed or has an error
      See Also:

    • removeConnectionEventListener

      public void removeConnectionEventListener(ConnectionEventListener listener)
      Removes the given event failover from the list of components that will be notified when an event occurs on this PooledConnection object.
      Specified by:
      removeConnectionEventListener in interface PooledConnection
      Parameters:
      listener - a component, usually the connection pool manager, that has implemented the ConnectionEventListener interface and been registered with this PooledConnection object as a failover
      See Also:

    • addStatementEventListener

      public void addStatementEventListener(StatementEventListener listener)
      Registers a StatementEventListener with this PooledConnection object. Components that wish to be notified when PreparedStatements created by the connection are closed or are detected to be invalid may use this method to register a StatementEventListener with this PooledConnection object.
      Specified by:
      addStatementEventListener in interface PooledConnection
      Parameters:
      listener - an component which implements the StatementEventListener interface that is to be registered with this PooledConnection object

    • removeStatementEventListener

      public void removeStatementEventListener(StatementEventListener listener)
      Removes the specified StatementEventListener from the list of components that will be notified when the driver detects that a PreparedStatement has been closed or is invalid.
      Specified by:
      removeStatementEventListener in interface PooledConnection
      Parameters:
      listener - the component which implements the StatementEventListener interface that was previously registered with this PooledConnection object

    • fireStatementClosed

      public void fireStatementClosed(Statement st)
      Fire statement close event to listeners.
      Parameters:
      st - statement

    • fireStatementErrorOccured

      public void fireStatementErrorOccured(Statement st, SQLException ex)
      Fire statement error to listeners.
      Parameters:
      st - statement
      ex - exception

    • fireConnectionClosed

      public void fireConnectionClosed()
      Fire Connection close to listening listeners.

    • fireConnectionErrorOccured

      public void fireConnectionErrorOccured(SQLException ex)
      Fire connection error to listening listeners.
      Parameters:
      ex - exception

    • noStmtEventListeners

      public boolean noStmtEventListeners()
      Indicate if there are any registered listener.
      Returns:
      true if no listener.

    • getLastUsed

      public AtomicLong getLastUsed()
      Indicate last time this pool connection has been used.
      Returns:
      current last used time (nano).

    • lastUsedToNow

      public void lastUsedToNow()
      Set last poolConnection use to now.
