public void putAll(java.util.Map<? extends java.lang.Double,? extends java.lang.Boolean> m)

  - double2BooleanEntrySet
```
public ObjectSet<Double2BooleanMap.Entry> double2BooleanEntrySet()
```
    Description copied from interface: Double2BooleanMap
    
    Returns a type-specific set view of the mappings contained in this map.
    This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Double2BooleanMap.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).
    
    Specified by:
    
    double2BooleanEntrySet in interface Double2BooleanMap
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.

  - keySet
```
public DoubleSet keySet()
```
    Description copied from interface: Double2BooleanMap
    
    Returns a set view of the keys contained in this map.
    Note that this specification strengthens the one given in Map.keySet().
    
    Specified by:
    
    keySet in interface Double2BooleanMap
    
    Specified by:
    
    keySet in interface java.util.Map<java.lang.Double,java.lang.Boolean>

    Description copied from interface: Double2BooleanMap

    Specified by:
    
    values in interface Double2BooleanMap
    
    Specified by:
    
    values in interface java.util.Map<java.lang.Double,java.lang.Boolean>
