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<java.lang.Integer,java.lang.Character>
    
    Specified by:
    
    size in interface java.util.Map<java.lang.Integer,java.lang.Character>
    
    Overrides:
    
    size in class Int2CharFunctions.SynchronizedFunction
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.

```
    Description copied from interface: Int2CharFunction
    
    Gets the default return value.
    
    Specified by:
    
    defaultReturnValue in interface Int2CharFunction
    
    Overrides:
    
    defaultReturnValue in class Int2CharFunctions.SynchronizedFunction
    
    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(char defRetValue)
```
    Description copied from interface: Int2CharFunction
    
    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 Int2CharFunction
    
    Overrides:
    
    defaultReturnValue in class Int2CharFunctions.SynchronizedFunction
    
    Parameters:
    
    defRetValue - the new default return value.

    Int2CharFunction.defaultReturnValue()
  - put
```
public char put(int k,
                char v)
```
    Description copied from interface: Int2CharFunction
    
    Adds a pair to the map.
    
    Specified by:
    
    put in interface Int2CharFunction
    
    Overrides:
    
    put in class Int2CharFunctions.SynchronizedFunction
    
    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.

  - int2CharEntrySet
```
public ObjectSet<Int2CharMap.Entry> int2CharEntrySet()
```
    Description copied from interface: Int2CharMap
    
    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 Int2CharMap.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:
    
    int2CharEntrySet in interface Int2CharMap
    
    Returns:

    Deprecated. Please use the corresponding type-specific method instead.
    
    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.
