```
public int size()
```
    Description copied from interface: Function
    
    Returns the intended number of keys in this function, or -1 if no such number exists.
    Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.
    
    Specified by:
    
    size in interface Function<K,Float>
    
    Specified by:
    
    size in interface Map<K,Float>
    
    Overrides:
    
    size in class Object2FloatFunctions.SynchronizedFunction<K>
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.
  - containsKey
```
public boolean containsKey(Object k)
```
    Description copied from interface: Function
    
    Returns true if this function contains a mapping for the specified key.
    Note that for some kind of functions (e.g., hashes) this method will always return true.
    
    Specified by:
    
    containsKey in interface Function<K,Float>
    
    Specified by:
    
    containsKey in interface Map<K,Float>
    
    Overrides:
    
    containsKey in class Object2FloatFunctions.SynchronizedFunction<K>
    
    Parameters:
    
    k - the key.
    
    Returns:
    
    true if this function associates a value to key.

    Map.containsKey(Object)
  - containsValue
```
public boolean containsValue(float v)
```
    Specified by:

  - defaultReturnValue
```

```
    Description copied from interface: Object2FloatFunction
    
    Gets the default return value.
    
    Specified by:

    defaultReturnValue in class Object2FloatFunctions.SynchronizedFunction<K>
    
    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(float defRetValue)
```
    Description copied from interface: Object2FloatFunction
    
    Sets the default return value. This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
    
    Specified by:
    
    defaultReturnValue in interface Object2FloatFunction<K>
    
    Overrides:
    
    defaultReturnValue in class Object2FloatFunctions.SynchronizedFunction<K>
    
    Parameters:
    
    defRetValue - the new default return value.
    
    See Also:
    
    Object2FloatFunction.defaultReturnValue()
  - put
```
public float put(K k,
                 float v)
```
    Description copied from interface: Object2FloatFunction
    
    Adds a pair to the map.
    
    Specified by:
    
    put in interface Object2FloatFunction<K>
    
    Overrides:
    
    put in class Object2FloatFunctions.SynchronizedFunction<K>
    
    Parameters:
    
    k - the key.
    
    v - the value.
    
    Returns:
    
    the old value, or the default return value if no value was present for the given key.

  - putAll
```
public void putAll(Map<? extends K,? extends Float> m)
```
    Specified by:
    
    putAll in interface Map<K,Float>
  - 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 objects of type Map.Entry (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 Map<K,Float>
    
    Returns:
    
    a set view of the keys contained in this map.
    
    See Also:
    
    Map.keySet()
  - values
```
public FloatCollection values()
```
    Description copied from interface: Object2FloatMap
    
    Returns a set view of the values contained in this map.
    Note that this specification strengthens the one given in Map.values().
    
    Specified by:
    
    values in interface Object2FloatMap<K>
    
    Specified by:
    
    values in interface Map<K,Float>
    
    Returns:
    
    a set view of the values contained in this map.

  - clear
```
public void clear()
```
    Description copied from interface: Function

    Specified by:
    
    clear in interface Function<K,Float>
    
    Specified by:
    
    clear in interface Map<K,Float>

  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object2FloatFunctions.SynchronizedFunction<K>
  - put
```
public Float put(K k,
                 Float v)
```
    Description copied from class: AbstractObject2FloatFunction
    
    Delegates to the corresponding type-specific method, taking care of returning null on a missing key.
    This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.
    
    Specified by:
    
    put in interface Function<K,Float>
    
    Specified by:
    
    put in interface Map<K,Float>

    Parameters:
    
    k - the key.
    
    v - the value.
    
    Returns:
    
    the old value, or null if no value was present for the given key.

    Parameters:
    
    k - the key.
    
    Returns:
    
    the old value, or the default return value if no value was present for the given key.
