Catalogs
Catalogs
The Catalogs namespace provides modules and interfaces that represent catalogs of
types of data and the services to support them. Currently the only catalog in the
namespace is for log channels. A log channel is a standard abbreviation used to designate
a well log of a particular type from a particular entity.
LogChannelCatalogModuleClass
The LogChannelCatalogModule class is a module that manages the log channels. It
implements the IModule interface. It may be loaded by the product family automatically
or may need to be added to the application configuration file. In either case, the lifecycle
of the module is handled by Ocean Core. The class is defined as:
public class LogChannelCatalogModule : IModule
{
public void Initialize ();
public void Integrate ();
public void IntegratePresentation ();
public void Disintegrate ();
public void Dispose ();
}
The module definition to be included in the application configuration file for the log
channel catalog is:
ILogChannel-Catalog Interface
The ILogChannelCatalog interface is a service to look up log channels based on
channel names or unit measurements. The object reference to the service is accessed by:
ILogChannelCatalog logChannelCat;
logChannelCat = CoreSystem.GetService();
