Base class for features.
class CFeature :public virtual IFeature, public CReleasable
{
protected:
CFeature(const String &name);
};The feature is just a class instance that is available globally. Let's say we need access to the user login and password in multiple places in an application. In this case we can create a feature like following.
class CUserConfig :public CFeature
{
private:
String m_sLogin;
String m_sPassword;
public:
String const &Login{ m_sLogin };
String const &Password{ m_sPassword };
CUserConfig(const String &login, const String &password) :
CFeature(L"UserConfig"),
m_sLogin{ login },
m_sPassword{ password }
{
}
};After it we can register a new feature at the application start.
int main()
{
CApplication app;
app.RegisterFeature(new CUserConfig(L"root", L"password"));
// ...
return 0;
}Now at any place in the application we can get access to user login and password in the following way.
String login{ cast<CUserConfig*>(Application->getFeature(L"UserConfig"))->Login };| Namespace: | nitisa |
