Class SingleConnectionDataSource

java.lang.Object

be.bendem.sqlstreams.util.SingleConnectionDataSource

All Implemented Interfaces:

Closeable, AutoCloseable, Wrapper, CommonDataSource, DataSource

public class SingleConnectionDataSource
extends Object
implements Closeable

Wraps a single connection that is reused each time getConnection() is called. Note that closing the connection you got using getConnection() will make it available again. If it is not closed, calling getConnection() will throw an IllegalStateException. To actually close the connection, call close() on this DataSource. Instances of this class are thread-safe, but the connections returned when calling getConnection() aren't.
