All Implemented Interfaces:

Localizable, LocalizableObject, Serializable

Direct Known Subclasses:

ObjectNotFoundUserException
```
public class ObjectNotFoundException
extends ApplicationException
```
An ObjectNotFoundException is thrown if an object was requested but does not exist or could not be found.
This typically happens in situations where required objects are requested by a key (e.g. in a registry- Map) but an expected object was not registered or the key is wrong for some reason.
If you design your API consider carefully if you should return null or throw an ObjectNotFoundException.

1.0.0

public String getCode()
```
    Description copied from class: ApplicationException
    
    This method gets the code that identifies the detailed type of this object. While UUID is unique per instance of a ApplicationException this code is a short and readable identifier representing the ApplicationException Class. The default implementation returns the simple name. However, the code should remain stable after refactoring (so at least after the rename the previous code should be returned as String literal). This code may be used as a compact identifier to reference the related problem or information as well as for automatic tests of error situations that should remain stable even if the message text gets improved or the locale is unknown.
    
    Overrides:
    
    getCode in class ApplicationException
    
    Returns:
    
    the error code.
