7 | * The ODMG Set collection interface. | |
8 | ||
9 | * A <code>DSet</code> object is an unordered collection that does not support | |
10 | ||
11 | * multiple elements with the same value. An implementation typically is very | |
12 | ||
13 | * efficient at determining whether the collection contains a particular value. | |
14 | ||
15 | * <p> | |
16 | ||
17 | * All of the operations defined by the JavaSoft <code>Set</code> | |
18 | ||
19 | * interface are supported by an ODMG implementation of <code>DSet</code>, | |
20 | ||
21 | * the exception <code>UnsupportedOperationException</code> is not thrown when a | |
22 | ||
23 | * call is made to any of the <code>Set</code> methods. | |
