  - applyAsDouble
```
public double applyAsDouble(K operand)
```
    Description copied from interface: Reference2FloatFunction
    
    Specified by:
    
    applyAsDouble in interface Reference2FloatFunction<K>
    
    Specified by:
    
    applyAsDouble in interface java.util.function.ToDoubleFunction<K>
  - apply
```
@Deprecated
public java.lang.Float apply(K key)
```
    Deprecated.
    Please use the corresponding type-specific method instead.
    
    This is equivalent to calling Function.get(Object).
    
    Specified by:
    
    apply in interface Function<K,java.lang.Float>
    
    Specified by:
    
    apply in interface java.util.function.Function<K,java.lang.Float>
    
    Parameters:
    
    key -
    
    Returns:
    
    See Also:
    
    Function.apply(Object), Function.get(Object)
  - size
```
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. This default implementation, in particular, returns -1.
    
    Specified by:
    
    size in interface Function<K,java.lang.Float>
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.
  - defaultReturnValue
```
public float defaultReturnValue()
```
    Description copied from interface: Reference2FloatFunction
    
    Gets the default return value.
    This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).
    
    Specified by:
    
    defaultReturnValue in interface Reference2FloatFunction<K>
    
    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(float defRetValue)
```
    Description copied from interface: Reference2FloatFunction
    
    Sets the default return value (optional operation). 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 Reference2FloatFunction<K>
    
    Parameters:
    
    defRetValue - the new default return value.
    
    See Also:
    
    Reference2FloatFunction.defaultReturnValue()
  - containsKey
```
public boolean containsKey(java.lang.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. This default implementation, in particular, always return true.
    
    Specified by:
    
    containsKey in interface Function<K,java.lang.Float>
    
    Parameters:
    
    k - the key.
    
    Returns:
    
    true if this function associates a value to key.
    
    See Also:
    
    Map.containsKey(Object)
  - put
```
public float put(K k,
                 float v)
```
    Description copied from interface: Reference2FloatFunction
    
    Adds a pair to the map (optional operation).
    
    Specified by:
    
    put in interface Reference2FloatFunction<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.
