/**
* Decorates another <code>Collection</code> to provide additional behaviour
* without guaranteeing that the provided <code>Collection</code> type is the
* same as that of the decorated <code>Collection</code>.
* <p>
* Each untyped method call made on this <code>Collection</code> is forwarded to the
* decorated <code>Collection</code>. This class is used as a framework on which
* to build to extensions such as synchronized and unmodifiable behaviour. The
* main advantage of decoration is that one decorator can wrap any
* implementation of <code>Collection</code>, whereas sub-classing requires a
* new class to be written for each implementation.
* <p>
* This implementation does not perform any special processing with
* {@link #iterator()}. Instead it simply returns the value from the wrapped
* collection. This may be undesirable, for example if you are trying to write
* an unmodifiable implementation it might provide a loophole.
*
* @param <D> the type of the elements in the decorated collection
* @param <E> the element type of the Collection implementation
* @since 4.0
