SysExtension class factory

Attribute class, which will be used to attribute each class in the hierarchy and instantiate the correct one. Should extend SysAttribute.

class VKCallCenterIntegrationAttribute extends SysAttribute
{
    VKCallCenterIntegrationActivity activityId;
}
public void new(VKCallCenterIntegrationActivity _activityId)
{
    super();

    activityId = _activityId;
}
public VKCallCenterIntegrationActivity parmActivityId(VKCallCenterIntegrationActivity _activityId = activityId)
{
    activityId = _activityId;

    return activityId;
}

construct method of the base class, which based on the enum instantiate the right class from the hierarchy:

public static VKCallCenterIntegration construct(VKCallCenterIntegrationActivity _activityId, LanguageId _languageId, container _parameters)
{
    VKCallCenterIntegration             callCenterIntegration;
    VKCallCenterIntegrationAttribute    callCenterIntegrationAttribute;

    if(_activityId)
    {
        callCenterIntegrationAttribute = new VKCallCenterIntegrationAttribute(_activityId);
        callCenterIntegration = SysExtensionAppClassFactory::getClassFromSysAttribute(classStr(VKCallCenterIntegration), callCenterIntegrationAttribute);
    }

    if(callCenterIntegration == null)
    {
        throw error(strfmt("Unknown activity type %1", _activityId));
    }

    callCenterIntegration.parmLanguageId(_languageId);
    callCenterIntegration.parmParameters(_parameters);
    callCenterIntegration.parmActivityId(_activityId);
    callCenterIntegration.init();

    return callCenterIntegration;
}

Child classes in the hierarchy should mention attribute value:

[VKCallCenterIntegrationAttribute(VKCallCenterIntegrationActivity::ClickAndCollect)]
class VKCallCenterIntegrationClickAndCollect extends VKCallCenterIntegration
{
}
