public EmbeddedConnectionProvider()

Method Detail

isPooled

public boolean isPooled()

Description copied from interface: ConnectionProvider

Returns true if this connection provider provides connections out of a connection pool. Implementing and using connection providers that are pooled is strongly recommended, as they greatly increase the speed of Jive.

Specified by:

isPooled in interface ConnectionProvider

Returns:

true if the Connection objects returned by this provider are pooled.

getConnection

public Connection getConnection()
                         throws SQLException

Description copied from interface: ConnectionProvider

Returns a database connection. When a Jive component is done with a connection, it will call the close method of that connection. Therefore, connection pools with special release methods are not directly supported by the connection provider infrastructure. Instead, connections from those pools should be wrapped such that calling the close method on the wrapper class will release the connection from the pool.

Specified by:

getConnection in interface ConnectionProvider

Returns:

a Connection object.

Throws:

SQLException - is an SQL error occured while retrieving the connection.

start

public void start()

Description copied from interface: ConnectionProvider

Starts the connection provider. For some connection providers, this will be a no-op. However, connection provider users should always call this method to make sure the connection provider is started.

Specified by:

start in interface ConnectionProvider

restart

public void restart()

Description copied from interface: ConnectionProvider

This method should be called whenever properties have been changed so that the changes will take effect.

Specified by:

restart in interface ConnectionProvider

destroy

public void destroy()

Description copied from interface: ConnectionProvider

Tells the connection provider to destroy itself. For many connection providers, this will essentially result in a no-op. However, connection provider users should always call this method when changing from one connection provider to another to ensure that there are no dangling database connections.

Specified by:

destroy in interface ConnectionProvider

finalize

public void finalize()
              throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
