  - - speiger.src.collections.doubles.maps.impl.hash.Double2IntOpenHashMap

All Implemented Interfaces:

java.util.function.DoubleToIntFunction, java.util.Map<java.lang.Double,java.lang.Integer>, Double2IntFunction, Double2IntMap

Direct Known Subclasses:

Double2IntLinkedOpenHashMap
```
public class Double2IntOpenHashMap
extends AbstractDouble2IntMap
```
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

                    IntIntUnaryOperator mappingFunction)
```
    Description copied from interface: Double2IntMap
    
    A Type Specific merge method to reduce boxing/unboxing
    
    Specified by:
    
    mergeInt in interface Double2IntMap
    
    Overrides:
    
    mergeInt in class AbstractDouble2IntMap
    
    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
  - mergeAllInt
```
public void mergeAllInt(Double2IntMap m,
                        IntIntUnaryOperator mappingFunction)
```
    Description copied from interface: Double2IntMap

    Overrides:
    
    mergeAllInt in class AbstractDouble2IntMap
    
    Parameters:
    
    m - the entries that should be bulk added
    
    mappingFunction - the operator that should generate the new Value
  - size
