Modifier and Type	Method and Description
`void`	`clear()` Removes all associations from this function (optional operation).
`boolean`	`containsKey(byte k)`
`boolean`	`containsKey(Object ok)` Returns true if this function contains a mapping for the specified key.
`long`	`defaultReturnValue()` Gets the default return value.
`void`	`defaultReturnValue(long defRetValue)` Sets the default return value.
`long`	`get(byte k)` Returns the value to which the given key is mapped.
`Long`	`get(Object k)` Delegates to the corresponding type-specific method, taking care of returning `null` on a missing key.

- Method Detail
  - 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.
    
    Specified by:
    
    size in interface Function<Byte,Long>
    
    Returns:
    the intended number of keys in this function, or -1 if that number is not available.
  - containsKey
```
public boolean containsKey(byte k)
```
    Specified by:
    
    containsKey in interface Byte2LongFunction
    
    See Also:
    Function.containsKey(Object)
  - defaultReturnValue
```
public long defaultReturnValue()
```
    Description copied from interface: Byte2LongFunction
    
    Gets the default return value.
    
    Specified by:
    
    defaultReturnValue in interface Byte2LongFunction
    
    Overrides:
    
    defaultReturnValue in class AbstractByte2LongFunction
    
    Returns:
    the current default return value.
  - defaultReturnValue
```
public void defaultReturnValue(long defRetValue)
```
    Description copied from interface: Byte2LongFunction
    
    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 Byte2LongFunction
    
    Overrides:
    
    defaultReturnValue in class AbstractByte2LongFunction
    
    Parameters:
    defRetValue - the new default return value.
    See Also:
    Byte2LongFunction.defaultReturnValue()
  - put
```
public long put(byte k,
       long v)
```
    Description copied from interface: Byte2LongFunction
    
    Adds a pair to the map.
    
    Specified by:
    
    put in interface Byte2LongFunction
    
    Overrides:
    
    put in class AbstractByte2LongFunction
    
    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)
  - clear
```
public void clear()
```
    Description copied from interface: Function
    
    Removes all associations from this function (optional operation).
    
    Specified by:
    
    clear in interface Function<Byte,Long>
    
    Overrides:
    
    clear in class AbstractByte2LongFunction

```
    Overrides:
    
    toString in class Object
  - put
```
public Long put(Byte k,
       Long v)
```
    Description copied from class: AbstractByte2LongFunction
    
    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<Byte,Long>
    
    Overrides:
    
    put in class AbstractByte2LongFunction
    
    Parameters:
    k - the key.
    v - the value.
    
    Returns:
    the old value, or null if no value was present for the given key.

    Map.put(Object,Object)
  - get
```
public Long get(Object k)
```
    Description copied from class: AbstractByte2LongFunction
    
    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:
    
    get in interface Function<Byte,Long>
    
    Overrides:
    
    get in class AbstractByte2LongFunction
    
    Parameters:
    k - the key.
    
    Returns:
    the corresponding value, or null if no value was present for the given key.

    Map.get(Object)
  - remove
```
public Long remove(Object k)
```
    Description copied from class: AbstractByte2LongFunction
    
    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:
    
    remove in interface Function<Byte,Long>
    
    Overrides:
    
    remove in class AbstractByte2LongFunction
    
    Returns:
    the old value, or null if no value was present for the given key.

    Map.remove(Object)
  - remove
```
public long remove(byte k)

    remove in interface Byte2LongFunction
    
    Overrides:
    
    remove in class AbstractByte2LongFunction
    
    Returns:
    the old value, or the default return value if no value was present for the given key.

```
    Description copied from interface: Byte2LongFunction
    
    Returns the value to which the given key is mapped.

    get in interface Byte2LongFunction
    
    Parameters:
    k - the key.
    
    Returns:
    the corresponding value, or the default return value if no value was present for the given key.

    Function.get(Object)
  - containsKey
```
public boolean containsKey(Object ok)
```
    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.

    containsKey in interface Function<Byte,Long>
    
    Overrides:
    
    containsKey in class AbstractByte2LongFunction
