Detailed Description

Persists a list of object groups that are themselves persisted. All creation and deletion of persistent object groups should result in the list store being updated. This is done to support multiple group factories using the same persistent object groups.

)

PortableGroup::ObjectGroupId TAO::PG_Group_List_Store::get_next_group_id

Return a group ID that can be used for creating a new object group.

bool TAO::PG_Group_List_Store::is_obsolete ( time_t  stored_time )

private

bool TAO::PG_Group_List_Store::list_obsolete

(

)

Answer if the list is obsolete because the persistent store has been updated. Used by PG_Group_Factory to avoid having to compare IDs in group_map_ with the list contained here.

void TAO::PG_Group_List_Store::stale

(

bool

is_stale

)

Make explicit that state is stale instead of relying only on persistent file time stamp.
