/**
 * A generic stream collection interface.
 * Mind you that you need to call {@link #close()} on this stream after use,
 * best with a {@code try}-with-resources statement.
 * For example, let's assume you would have an object named {@code container}
 * which has a method named {@code stream()} which returns a
 * {@code Stream}.
 * Then you should use this method like this:
 * 

 * 
{@code
 * try (Stream stream = container.stream()) {
 *     for (Object object : stream) {
 *         // Use object here...
 *     }
 * }
 * }
 * The {@code try}-with-resources statement ensures that {@code stream} gets
 * {@code close()}d after the {@code for}-loop, even if it terminates with an
 * exception.
 * 
 * @param   The type of the elements in the stream.
 * @since  TrueCommons 1.0.12
