public class Byte2CharRBTreeMap
extends AbstractByte2CharSortedMap
implements Serializable, Cloneable, Byte2CharSortedMap

A type-specific red-black tree map with a fast, small-footprint implementation.

The iterators provided by the views of this class are type-specific bidirectional iterators. Moreover, the iterator returned by iterator() can be safely cast to a type-specific list iterator.

Method Detail

put

public final char put(byte k,
                      char v)
Description copied from interface: Byte2CharMap
Adds a pair to the map.

Specified by:
put in interface Byte2CharMap
Overrides:
put in class AbstractByte2CharMap

remove

public final char remove(byte k)
Description copied from interface: Byte2CharMap
Removes the mapping with the given key.

Specified by:
remove in interface Byte2CharMap
Overrides:
remove in class AbstractByte2CharMap

put

public Object put(Object ok,
                  Object ov)
Description copied from class: AbstractByte2CharMap
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 Map
Overrides:
put in class AbstractByte2CharMap

remove

public Object remove(Object ok)
Description copied from class: AbstractByte2CharMap
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 Map
Overrides:
remove in class AbstractByte2CharMap

containsValue

public boolean containsValue(char v)
Description copied from class: AbstractByte2CharMap
Checks whether the given value is contained in AbstractByte2CharMap.values().

Specified by:
containsValue in interface Byte2CharMap
Overrides:
containsValue in class AbstractByte2CharMap

clear

public void clear()
Specified by:
clear in interface Map
Overrides:
clear in class AbstractByte2CharMap

containsKey

public boolean containsKey(byte k)
Description copied from class: AbstractByte2CharMap
Checks whether the given value is contained in AbstractByte2CharMap.keySet().

Specified by:
containsKey in interface Byte2CharMap
Overrides:
containsKey in class AbstractByte2CharMap

size

public int size()
Specified by:
size in interface Map

isEmpty

public boolean isEmpty()
Specified by:
isEmpty in interface Map
Overrides:
isEmpty in class AbstractByte2CharMap

get

public char get(byte k)
Description copied from interface: Byte2CharMap
Returns the value to which the given key is mapped.

Specified by:
get in interface Byte2CharMap
Parameters:
k - the key.
Returns:
the corresponding value, or the default return value if no value was present for the given key.

Map.get(Object)

get

public Object get(Object ok)
Description copied from class: AbstractByte2CharMap
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 Map
Overrides:
get in class AbstractByte2CharMap

firstByteKey

public byte firstByteKey()
Specified by:
firstByteKey in interface Byte2CharSortedMap
See Also:
SortedMap.firstKey()

lastByteKey

public byte lastByteKey()
Specified by:
lastByteKey in interface Byte2CharSortedMap
See Also:
SortedMap.lastKey()

firstKey

public Object firstKey()

entrySet

public Set entrySet()
Specified by:
entrySet in interface Map

keySet

public Set keySet()
Returns a type-specific sorted set view of the keys contained in this map.

In addition to the semantics of Map.keySet(), you can safely cast the set returned by this call to a type-specific sorted set interface.

Specified by:
keySet in interface Map
Overrides:
keySet in class AbstractByte2CharSortedMap
Returns:
a type-specific sorted set view of the keys contained in this map.

values

public Collection values()
Returns a type-specific collection view of the values contained in this map.

In addition to the semantics of Map.values(), you can safely cast the collection returned by this call to a type-specific collection interface.

Specified by:
values in interface Map
Overrides:
values in class AbstractByte2CharMap
Returns:
a type-specific collection view of the values contained in this map.

comparator

public Comparator comparator()

clone

public Object clone()
Returns a deep copy of this tree map.

This method performs a deep copy of this tree map; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.

Returns:
a deep copy of this tree map.
