public class Short2ShortRBTreeMap
extends AbstractShort2ShortSortedMap
implements Serializable, Cloneable, Short2ShortSortedMap

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 short put(short k,
                 short v)
Description copied from interface: Short2ShortMap
Adds a pair to the map.

Specified by:
put in interface Short2ShortMap
Overrides:
put in class AbstractShort2ShortMap

remove

public short remove(short k)
Description copied from interface: Short2ShortMap
Removes the mapping with the given key.

Specified by:
remove in interface Short2ShortMap
Overrides:
remove in class AbstractShort2ShortMap

put

public Object put(Object ok,
                  Object ov)
Description copied from class: AbstractShort2ShortMap
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 AbstractShort2ShortMap

remove

public Object remove(Object ok)
Description copied from class: AbstractShort2ShortMap
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 AbstractShort2ShortMap

containsValue

public boolean containsValue(short v)
Description copied from class: AbstractShort2ShortMap
Checks whether the given value is contained in AbstractShort2ShortMap.values().

Specified by:
containsValue in interface Short2ShortMap
Overrides:
containsValue in class AbstractShort2ShortMap

clear

public void clear()
Specified by:
clear in interface Map
Overrides:
clear in class AbstractShort2ShortMap

containsKey

public boolean containsKey(short k)
Description copied from class: AbstractShort2ShortMap
Checks whether the given value is contained in AbstractShort2ShortMap.keySet().

Specified by:

size

public int size()
Specified by:

Description copied from interface: Short2ShortMap
Returns the value to which the given key is mapped.

Specified by:
get in interface Short2ShortMap
Parameters:
k - the key.
Returns:
the corresponding value, or the default return value if no value was present for the given key.

get

public Object get(Object ok)
Description copied from class: AbstractShort2ShortMap
Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

firstShortKey

public short firstShortKey()
Specified by:
firstShortKey in interface Short2ShortSortedMap

keySet

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

Overrides:
keySet in class AbstractShort2ShortSortedMap
Returns:
a type-specific sorted set view of the keys contained in this map.

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.
