NullObjektMuster
NullObjektMuster is a design pattern in object-oriented programming languages that allows objects to have a common default behavior when their data is missing or has an undefined value. The concept is also known as the Null Object Pattern or Empty Reference Pattern.
In programming, a null object is an object that has been initialized to point to no valid
The NullObjektMuster usually consists of two classes: the default object (NullObject) and a quick-result object (DefaultObject).
To apply the NullObjektMuster, the following key steps are typically taken:
1. Create a NullObject class that can be used as a placeholder when no valid object is
2. When a request for a particular object type is made, first check if it is of
3. If it is the NullObject, use it instead of the actual object to assign a default
The NullObjektMuster is a common object-oriented design pattern that is known for its reliability and robustness
