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