Type Parameters:

T_IdKeyPair - the type of the id key pair.

T_IdKey - the type of the id key.

T_PreKey - the prekey type

T_SigPreKey - the signed prekey type.

T_Sess - the session type.

SignalCachingOmemoStore

public class CachingOmemoStore<T_IdKeyPair,T_IdKey,T_PreKey,T_SigPreKey,T_Sess,T_Addr,T_ECPub,T_Bundle,T_Ciph>
extends OmemoStore<T_IdKeyPair,T_IdKey,T_PreKey,T_SigPreKey,T_Sess,T_Addr,T_ECPub,T_Bundle,T_Ciph>

This class implements the Proxy Pattern in order to wrap an OmemoStore with a caching layer. This reduces access to the underlying storage layer (eg. database, filesystem) by only accessing it for missing/updated values. Alternatively this implementation can be used as an ephemeral keystore without a persisting backend.
