    Parameters:
    
    fromElement - the element the iterator should start from
    
    Returns:
    
    a iterator starting from the given element
  - copy
```
public ImmutableDoubleOpenHashSet copy()
```
    Description copied from interface: DoubleCollection
    
    A Function that does a shallow clone of the Collection itself. This function is more optimized then a copy constructor since the Collection does not have to be unsorted/resorted. It can be compared to Cloneable but with less exception risk
    
    Specified by:
    
    copy in interface DoubleCollection
    
    Specified by:
    
    copy in interface DoubleOrderedSet
    
    Specified by:
    
    copy in interface DoubleSet
    
    Overrides:
    
    copy in class AbstractDoubleSet
    
    Returns:
    
    a Shallow Copy of the collection
  - clear
```
public void clear()
```
    Specified by:
    
    clear in interface java.util.Collection<java.lang.Double>
    
    Specified by:
    
    clear in interface java.util.Set<java.lang.Double>
    
    Overrides:
    
    clear in class java.util.AbstractCollection<java.lang.Double>
  - size
```
public int size()
```
    Specified by:
    
    size in interface java.util.Collection<java.lang.Double>
    
    Specified by:
    
    size in interface java.util.Set<java.lang.Double>
    
    Specified by:
    
    size in class java.util.AbstractCollection<java.lang.Double>
