Overview

VLocalConnection Controller - provides access to the content of a local Valentina database.

To use VLocalConnection you should set Valentina.Init() parameters: cacheSize and serial (if you have it).

Tasks

Please familiarise with tasks of all controllers before programming your application. Some tasks may be invoked and executed by high-level's objects. And you should not invoke them directly.

Class Methods

- (NSString*)serial;

setSerial:

Establishes serial of Valentina. - (void)setSerial:(NSString*)inSerial;
