Class OneSharedConnectionDataSource

java.lang.Object
  com.googlecode.jdbw.util.OneSharedConnectionDataSource

All Implemented Interfaces:

Wrapper, CommonDataSource, DataSource

public class OneSharedConnectionDataSource
extends Object
implements DataSource

Very primitive database connection source which only keeps one connection in the pool. There is no reconnection logic or anything, it just hands out the same connection to one user at a time. Calling getConnection() on this object while another process is using that connection will block until the connection is returned to the pool.
