struct | _persistence_list |
This class provides a mechanism for users to access definitions from different definition stores, such as from a MySQL database, a file, or volatile stores.
Users can add different BESDefinitionStorage instances to this persistent list. Then, when a user looks for a definition, that search goes through the list of persistent stores in the order they were added to this list.

bool BESDefinitionStorageList::add_persistence | ( | BESDefinitionStorage * | cp | ) | [virtual] |
Add a persistent store to the list.
Each persistent store has a name. If a persistent store already exists in the list with that name then the persistent store is not added. Otherwise the store is added to the list.
The persistent stores are searched in the order in which they were added.
cp | persistent store to add to the list |

void BESDefinitionStorageList::show_definitions | ( | BESInfo & | info | ) | [virtual] |
show information for each definition in each persistence store
For each definition in each persistent store, add infomation about each of those definitions. The information added to the information object includes the persistent store name, in the order the persistent stores are searched, followed by a line for each definition within that persistent store which includes the name of the definition, information about each container used by that definition, the aggregation server being used and the aggregation command being used if aggregation is specified.
info | object to store the definition and persistent store information |
