Direct Known Subclasses:

Long2LongLinkedOpenHashMap
```
public class Long2LongOpenHashMap
extends AbstractLong2LongMap
```
A Type Specific Custom implementation of the HashMap Instead of using Wrapper Object Arrays for storing keys and values there is dedicated arrays for storing keys and values. Extra to that there is a couple quality of life functions provided

    Overrides:
    
    mergeLong in class AbstractLong2LongMap
    
    Parameters:
    
    key - the key that should be be searched for
    
    value - the value that should be merged with
    
    mappingFunction - the operator that should generate the new Value
    
    Returns:
    
    the result of the merge
