CoreSystem Class
discussed in the section “ServiceLocator Class” on page 3-71. However, two of the
overloads in CoreSystem are .NET generic convenience wrappers that are not available
on the ServiceLocator class and therefore are covered here. These versions are
defined as:
public static T GetService() where T : class;
and
public static T GetService(object source) where T : class;
They are .NET generic convenience wrappers for the GetService(Type) and
GetService(object, Type) methods respectively and can be used in place of:
MyObject mo = CoreSystem.GetService(typeof(MyObject)) as MyObject;
Use of the .NET generic convenience wrapper gives:
MyObject mo = CoreSystem.GetService();
The method taking the source object would look like:
object source = ...;
MyObject mos = CoreSystem.GetService(source);
State Property
The CoreSystem.State property returns the current state of the system. You may use
it to determine if the system is initializing, integrating, running, etc.
...
// See if all initialization is complete.
// If we’re running then do something.
if (CoreSystem.State == SystemState.Running)
{
...
}
The Ocean Core SystemState enumeration defines the possible system states which
are:
• None – The system is in an unknown state.
