```
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,java.lang.Boolean>
    
    Specified by:
    
    size in interface java.util.Map<K,java.lang.Boolean>
    
    Overrides:
    
    size in class Object2BooleanFunctions.UnmodifiableFunction<K>
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.
  - 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.
    
    Specified by:
    
    containsKey in interface Function<K,java.lang.Boolean>
    
    Specified by:
    
    containsKey in interface java.util.Map<K,java.lang.Boolean>
    
    Overrides:
    
    containsKey in class Object2BooleanFunctions.UnmodifiableFunction<K>
    
    Parameters:
    
    k - the key.
    
    Returns:
    
    true if this function associates a value to key.

    Map.containsKey(Object)
  - containsValue
```
public boolean containsValue(boolean v)
```
    Specified by:
    
    containsValue in interface Object2BooleanMap<K>
    
    See Also:
    
    Map.containsValue(Object)
  - defaultReturnValue
```
public boolean defaultReturnValue()
```
    Description copied from interface: Object2BooleanFunction
    
    Gets the default return value.
    
    Specified by:
    
    defaultReturnValue in interface Object2BooleanFunction<K>
    
    Overrides:
    
    defaultReturnValue in class Object2BooleanFunctions.UnmodifiableFunction<K>
    
    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(boolean defRetValue)
```
    Description copied from interface: Object2BooleanFunction
    
    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 Object2BooleanFunction<K>
    
    Overrides:
    
    defaultReturnValue in class Object2BooleanFunctions.UnmodifiableFunction<K>
    
    Parameters:
    
    defRetValue - the new default return value.
    
    See Also:
    
    Object2BooleanFunction.defaultReturnValue()
  - put
```
public boolean put(K k,
                   boolean v)
```
    Description copied from interface: Object2BooleanFunction
    
    Adds a pair to the map.
    
    Specified by:
    
    put in interface Object2BooleanFunction<K>
    
    Overrides:
    
    put in class Object2BooleanFunctions.UnmodifiableFunction<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.
    
    See Also:
    
    Function.put(Object,Object)
  - putAll
```
public void putAll(java.util.Map<? extends K,? extends java.lang.Boolean> m)
```
    Specified by:
    
    putAll in interface java.util.Map<K,java.lang.Boolean>
  - object2BooleanEntrySet
```
public ObjectSet<Object2BooleanMap.Entry<K>> object2BooleanEntrySet()
```
    Description copied from interface: Object2BooleanMap
    
    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 Object2BooleanMap.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:
    
    object2BooleanEntrySet in interface Object2BooleanMap<K>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.

  - keySet
```
public ObjectSet<K> keySet()
```
