36 /**
37  * Interface for releasing a connection.
38  * This can be implemented by various "trigger" objects which are
39  * associated with a connection, for example
40  * a {@link EofSensorInputStream stream}
41  * or an {@link BasicManagedEntity entity}
42  * or the {@link ManagedClientConnection connection} itself.
43  * <br/>
44  * The methods in this interface can safely be called multiple times.
45  * The first invocation releases the connection, subsequent calls
46  * are ignored.
