  - containsValue

public boolean containsValue(float v)

    containsValue in interface Object2FloatMap<K>

    Map.containsValue(Object)
  - putAll

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

  - object2FloatEntrySet
```
public ObjectSet<Object2FloatMap.Entry<K>> object2FloatEntrySet()
```
    Description copied from interface: Object2FloatMap
    
    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 Object2FloatMap.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:
    
    object2FloatEntrySet in interface Object2FloatMap<K>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.
    
    See Also:
    
    Object2FloatMap.entrySet()
  - keySet
```
public ObjectSet<K> keySet()
```
    Description copied from interface: Object2FloatMap
    
    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 Object2FloatMap<K>
    
    Specified by:
    
    keySet in interface java.util.Map<K,java.lang.Float>

public FloatCollection values()
```
    Description copied from interface: Object2FloatMap
    
    Returns a set view of the values contained in this map.

    values in interface Object2FloatMap<K>
    
    Specified by:
