Field Detail

statementEventListeners

private final java.util.concurrent.CopyOnWriteArrayList<javax.sql.StatementEventListener> statementEventListeners

List of statement event listeners. The list is copied on each write, ensuring that it can be safely iterated over even if other threads or the listeners fired in the same thread add or remove listeners.

Method Detail

removeStatementEventListener

public void removeStatementEventListener(javax.sql.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.

Parameters:

listener - the component which implements the StatementEventListener interface that was previously registered with this PooledConnection object

addStatementEventListener

public void addStatementEventListener(javax.sql.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.

Parameters:

listener - an component which implements the StatementEventListener interface that is to be registered with this PooledConnection object

onStatementClose

public void onStatementClose(java.sql.PreparedStatement statement)

Raise the statementClosed event for all the listeners when the corresponding events occurs

Overrides:

onStatementClose in class ClientPooledConnection

Parameters:

statement - The PreparedStatement that was closed

onStatementErrorOccurred

public void onStatementErrorOccurred(java.sql.PreparedStatement statement,
                                     java.sql.SQLException sqle)

Raise the statementErrorOccurred event for all the listeners when the corresponding events occurs.

Overrides:

onStatementErrorOccurred in class ClientPooledConnection

Parameters:

statement - The PreparedStatement on which error occurred

sqle - The SQLException associated with the error that caused the invalidation of the PreparedStatements
