This class uses ACE's Allocators to manage a memory representation of a configuraiton database. A persistent heap may be used to store configurations persistently
Note: Before using this class you must call one of the open methods.

method to enumerate through the <name> subsections in <key>. To begin iteration, <index> must zero. to continue iteration, invoke enumerate_sections again while incrementing index. Each iteration will return the <name> of the sub section. This method returns 0 on success, <0 on error and 1 when there are no more subsections to iterate through. Note - you may not delete or add values while enumerating. If you need to do this, you start the enumeration over again. Reimplemented from ACE_Configuration. |
