/**+
−
When the data of a user defined rules, names and IDs are sent from the server+
−
to the client, the size of the data is requested first and then, the client can +
−
create a data buffer and send it to the server to fill the data.+
−
+
−
Therefore, some client-server calls (e.g. CTzUserData::ReadRulesL(),+
−
CTzUserData::ReadNamesL(), CTzUserData::GetTzIdsL() must be carried out in two+
−
steps:+
−
+
−
- Get the size of the data to allow client to create data buffer+
−
- Get the data using this buffer+
−
+
−
The class CTzUserDataCache is for:+
−
+
−
- Find the data size+
−
- Cache the data+
−
- Retrieve cached data+
