Public Member Functions | |
| CachedNodeMap (const CachedNodeMap &m) | |
| Copy constructor. | |
| CachedNodeMap (warehouse::Collection< M > *coll) | |
| Construct a CachedNodeMap from a Collection. The caller is responsible for the Collection object, which must stay alive as long as this object does. | |
| CachedNodeMap (warehouse::WarehouseClient *client, const std::string &name) | |
| Construct a CachedNode map from an existing WarehouseClient object. The caller is responsible for the WarehouseClient object, which must be alive as long as this object is. | |
| M::ConstPtr | get (unsigned n) const |
| Get the message associated with this node. Calls out to the warehouse only if the message is not found in the cache. | |
| bool | hasData (unsigned n) const |
| Does this node have associated node data? Calls out to the warehouse unless the data is present in the cache. | |
| void | set (unsigned n, const M &m) |
| Set the message associated with this node and publish it to the warehouse. Remove any existing message. | |
| void | set (unsigned n, typename M::ConstPtr) |
| Set the message associated with this node and publish it to the warehouse. Remove any existing message. | |
Private Member Functions | |
| void | initialLoad () |
| Load all messages initially present. | |
| void | removeExisting (unsigned n) |
| Remove existing messages for a given node. | |
| void | updateCB (const warehouse::UpdateNotification &m) |
| Callback when collection is updated. | |
