HashMultiSet (Relana 1.0 Test API)

java.lang.Object
- eu.simuline.util.AbstractMultiSet<Map<T,MultiSet.Multiplicity>,T>
- - eu.simuline.util.HashMultiSet<T>

Type Parameters:

T - the class of the elements of this multi-set.

All Implemented Interfaces:

MultiSet<T>, Iterable<T>
```
public final class HashMultiSet<T>
extends AbstractMultiSet<Map<T,MultiSet.Multiplicity>,T>
implements MultiSet<T>
```
Represents a set with multiplicities based on a HashMap. Mathematically this is something between a set and a family. Note that this kind of set does support null elements.

```
    Creates a new, empty MultiSet.
  - HashMultiSet
```
public HashMultiSet(MultiSet<? extends T> other)

- Method Detail
  - getSet
```
public Set<T> getSet()
```
    Returns a view of the underlying set of this MultiSet. For certain implementations, this set is immutable to prevent implicit modification of this MultiSet.
    
    Specified by:
    
    getSet in interface MultiSet<T>
    
    Returns:
    
    the Set containing exactly the objects with strictly positive multiplicity in this MultiSet.
  - getMap
```
public Map<T,MultiSet.Multiplicity> getMap()
```
    Returns a view of the underlying map of this MultiSet as a map mapping each entry to its multiplicity.
    
    Specified by:
    
    getMap in interface MultiSet<T>
  - toString
```
public String toString()
```
    Specified by:
    
    toString in interface MultiSet<T>
    
    Overrides:
    
    toString in class Object
