-* The base interface for all ODMG collections.
-* The ODMG collections are based on JavaSoft’s collection interfaces.
-* All of the operations defined by the JavaSoft <code>Collection</code>
-* interface are supported by an ODMG implementation of <code>DCollection</code>;
-* the exception <code>UnsupportedOperationException</code> is not thrown when a
-* call is made to any of the <code>Collection</code> methods.
-* <p>
-* <code>DCollection</code> contains methods used to perform queries on the collection.
-* The OQL query predicate is given as a string with the syntax of the
-* <code>where</code> clause of OQL. The predefined OQL variable <code>this</code>
-* is used inside the predicate to denote the current element of the collection.
