| * File: ElemDDLPartitionList.h |
| * Description: class for lists of Partition elements specified in DDL |
| * statements. Each Partition element contains all legal |
| * partition attributes associating with the partition. |
| * For the partition attributes that are not specified |
| * (in DDL statements), the default values are used. |
| * |
| * Note that class ElemDDLPartitionList is derived from |
| * the base class ElemDDLList; therefore, the class |
| * ElemDDLPartitionList also represents a left linear |
| * tree. |
| * |
| * |
| * Created: 4/7/95 |
| * Language: C++ |
