Each instance of the {\tt DBStorageLayout} class describes a physical
storage layout for an MDD object or collection.
Every storage parameter which is not defined using the proper set* methods will result in a default value to be returned. the supports* methods will tell if the value is a default value defined at instantiation time through the static storagemgr/StorageLayout attributes or an explicitly defined value.
For information on the meaning of these attributes refere to storagemgr/storagelayout
