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<Integer,Byte>

Specified by:

size in interface Map<Integer,Byte>

Overrides:

size in class Int2ByteFunctions.SynchronizedFunction

Returns:

the intended number of keys in this function, or -1 if that number is not available.

containsKey

public boolean containsKey(int k)

Specified by:

containsKey in interface Int2ByteFunction

Overrides:

containsKey in class Int2ByteFunctions.SynchronizedFunction

See Also:

Function.containsKey(Object)

containsValue

public boolean containsValue(byte v)

Specified by:

containsValue in interface Int2ByteMap

See Also:

Map.containsValue(Object)

defaultReturnValue

public byte defaultReturnValue()

Description copied from interface: Int2ByteFunction

Gets the default return value.

Specified by:

defaultReturnValue in interface Int2ByteFunction

Overrides:

defaultReturnValue in class Int2ByteFunctions.SynchronizedFunction

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(byte defRetValue)

Description copied from interface: Int2ByteFunction

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 Int2ByteFunction

Overrides:

defaultReturnValue in class Int2ByteFunctions.SynchronizedFunction

Parameters:

defRetValue - the new default return value.

See Also:

Int2ByteFunction.defaultReturnValue()

put

public byte put(int k,
                byte v)

Description copied from interface: Int2ByteFunction

Adds a pair to the map.

Specified by:

put in interface Int2ByteFunction

Overrides:

put in class Int2ByteFunctions.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.

See Also:

Function.put(Object,Object)

putAll

public void putAll(Map<? extends Integer,? extends Byte> m)

Specified by:

putAll in interface Map<Integer,Byte>

int2ByteEntrySet

public ObjectSet<Int2ByteMap.Entry> int2ByteEntrySet()

Description copied from interface: Int2ByteMap

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 Int2ByteMap.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:

int2ByteEntrySet in interface Int2ByteMap

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Int2ByteMap.entrySet()

keySet

public IntSet keySet()

Description copied from interface: Int2ByteMap

Returns a set view of the keys contained in this map.

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Int2ByteMap

Specified by:

keySet in interface Map<Integer,Byte>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ByteCollection values()

Description copied from interface: Int2ByteMap

Returns a set view of the values contained in this map.

Note that this specification strengthens the one given in Map.values().

Specified by:

values in interface Int2ByteMap

Specified by:

values in interface Map<Integer,Byte>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

clear

public void clear()

Description copied from interface: Function

Removes all associations from this function (optional operation).

Specified by:

clear in interface Function<Integer,Byte>

Specified by:

clear in interface Map<Integer,Byte>

Overrides:

clear in class Int2ByteFunctions.SynchronizedFunction

See Also:

Map.clear()

toString

public String toString()

Overrides:

toString in class Int2ByteFunctions.SynchronizedFunction

put

@Deprecated
public Byte put(Integer k,
                            Byte v)

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.

Specified by:

put in interface Function<Integer,Byte>

Specified by:

put in interface Map<Integer,Byte>

Overrides:

put in class Int2ByteFunctions.SynchronizedFunction

Parameters:

k - the key.

v - the value.

Returns:

the old value, or null if no value was present for the given key.

See Also:

Map.put(Object,Object)

remove

@Deprecated
public byte remove(int k)

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

Removes the mapping with the given key.

Specified by:

remove in interface Int2ByteFunction

Overrides:

remove in class Int2ByteFunctions.SynchronizedFunction

Parameters:

k - the key.

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.remove(Object)

get

@Deprecated
public byte get(int k)

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

Returns the value to which the given key is mapped.

Specified by:

get in interface Int2ByteFunction

Overrides:

get in class Int2ByteFunctions.SynchronizedFunction

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

See Also:

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.

Specified by:

containsKey in interface Function<Integer,Byte>

Specified by:

containsKey in interface Map<Integer,Byte>

Overrides:

containsKey in class Int2ByteFunctions.SynchronizedFunction

Parameters:

ok - the key.

Returns:

true if this function associates a value to key.

See Also:

Map.containsKey(Object)

containsValue

@Deprecated
public boolean containsValue(Object ov)

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

Specified by:

containsValue in interface Map<Integer,Byte>

isEmpty

Specified by:

isEmpty in interface Map<Integer,Byte>

entrySet

public ObjectSet<Map.Entry<Integer,Byte>> entrySet()

Description copied from interface: Int2ByteMap

Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:
