@Deprecated
public Integer apply(Long key)
```
    Deprecated. Please use the corresponding type-specific method instead.
    
    This is equivalent to calling Function.get(Object).
    
    Specified by:

    Parameters:
    
    key -

```
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.
    
    Returns:
    
    the intended number of keys in this function, or -1 if that number is not available.
  - defaultReturnValue
```
public int defaultReturnValue()
```
    Description copied from interface: Long2IntFunction
    
    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 Long2IntFunction
    
    Returns:
    
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(int defRetValue)
```
    Description copied from interface: Long2IntFunction
    
    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 Long2IntFunction
    
    Parameters:
    
    defRetValue - the new default return value.

public boolean containsKey(long k)
```
    Description copied from interface: Long2IntFunction
    
    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. In particular, this default implementation always returns true.
    
    Specified by:
    
    containsKey in interface Long2IntFunction
    
    Parameters:
    
    k - the key.
    
    Returns:
    
    true if this function associates a value to key.
    
    See Also:
    
    Function.containsKey(Object)
  - containsKey
```
@Deprecated
public boolean containsKey(Object k)
```
    Deprecated.
    
    Description copied from interface: Long2IntFunction
