  - getOrCreate
```
default Map<K,V> getOrCreate()
```
    Specified by:
    
    getOrCreate in interface WritableContainerValue<K,V>
    
    Returns:
    
    the current null-safe value. Unlike ReadableValue.getSafe() this method will modify and initialize the value with an empty mutable container if it was null.
