DatabaseConnections

public interface Connections

Interface for a store of connection information.

Method Summary

void	addConnection(java.lang.String connName, java.util.Properties props) Creates a connection in the underlying namespace with the given name and properties.
void	addDisconnectListener(DisconnectListener l) Adds a listener to be asked about and notified of disconnect events.
void	addListener(ConnectionsListener l) Adds a listener to be notified of add/remove/update events in this connection store.
void	disconnect(java.lang.String connName) If the connection store has a cached connection for this connection name then disconnect it.
java.util.Properties	getProperties(java.lang.String connName) Returns a Properties object containing the properties for the given connection name.
javax.naming.Referenceable	getReferenceable(java.lang.String connName) Returns the Referenceable for the given connection name, containing the details about the connection.
java.util.Collection<java.lang.String>	listConnections() Lists the names of the available connections.
java.util.Collection<java.lang.String>	listConnections(java.util.Properties props) Lists any connections whose properties match the values in the given set.
boolean	removeConnection(java.lang.String connName) Removes the connection with the given name.
boolean	removeDisconnectListener(DisconnectListener l) Removes the given listener from this store if it was registered.
boolean	removeListener(ConnectionsListener l) Removes the given listener from this store if it was registered.
void	saveConnections() Saves this connection store.
void	testConnection(java.util.Properties props) Takes the given properties for a connection and attempts to create an actual connection to test the properties are valid.
boolean	updateConnection(java.lang.String connName, java.lang.String newName, java.util.Properties newProps) Updates the definition of the given connection with the new set of properties.

Method Detail

addListener

void addListener(ConnectionsListener l)

Adds a listener to be notified of add/remove/update events in this connection store.

removeListener

boolean removeListener(ConnectionsListener l)

Removes the given listener from this store if it was registered.

addDisconnectListener

void addDisconnectListener(DisconnectListener l)

Adds a listener to be asked about and notified of disconnect events.

removeDisconnectListener

boolean removeDisconnectListener(DisconnectListener l)

Removes the given listener from this store if it was registered.

listConnections

java.util.Collection<java.lang.String> listConnections()

Lists the names of the available connections.

listConnections

java.util.Collection<java.lang.String> listConnections(java.util.Properties props)

Lists any connections whose properties match the values in the given set. The connections can have extra properties, but they must have the key/value pairs in the given object.

getReferenceable

javax.naming.Referenceable getReferenceable(java.lang.String connName)
                                            throws ConnectionException

Returns the Referenceable for the given connection name, containing the details about the connection. The returned object is the object stored in the underlying namespace.

Throws:

ConnectionException - if an error occurs locating the given connection name.

getProperties

java.util.Properties getProperties(java.lang.String connName)
                                   throws ConnectionException

Returns a Properties object containing the properties for the given connection name. The Properties are a copy of those stored in the underlying Referenceable.

Throws:

ConnectionException - if an error occurs locating the given connection name.

addConnection

void addConnection(java.lang.String connName,
                   java.util.Properties props)
                   throws ConnectionException

Creates a connection in the underlying namespace with the given name and properties.

Throws:

ConnectionException

removeConnection

boolean removeConnection(java.lang.String connName)
                         throws ConnectionException

Removes the connection with the given name. It will return true if the operation succeeded, and false if no such connection exists to remove.

Parameters:

connName - the name of the connection to remove

Returns:

true if successful, false if connName not found

Throws:

ConnectionException - if an error is encountered removing the connection

disconnect

void disconnect(java.lang.String connName)
                throws ConnectionException

If the connection store has a cached connection for this connection name then disconnect it. Will do nothing if no connection is cached.

Parameters:

connName - the connection to disconnect

Throws:

ConnectionException - if an error is encountered getting or disconnecting the connection.

updateConnection

boolean updateConnection(java.lang.String connName,
                         java.lang.String newName,
                         java.util.Properties newProps)
                         throws ConnectionException

Updates the definition of the given connection with the new set of properties.

Parameters:

connName - the name of the connection as already defined

newName - the new name for the connection. if null the old name is kept

newProps - the new Properties for the connection.

Returns:

true if the update operation suceeded. Possible reasons for failure include a veto of the existing connection being closed before the update.

Throws:

ConnectionException

testConnection

void testConnection(java.util.Properties props)
                    throws ConnectionException

Takes the given properties for a connection and attempts to create an actual connection to test the properties are valid.

Throws:

ConnectionException

saveConnections

void saveConnections()
                     throws ConnectionException

Saves this connection store.

Throws:

IOException

ConnectionException
