Constructor Detail

Node

Node(K key,
     V value)

Make a new cell with given key and value, and with null links, and black (true) colors.

Parameters:

key - the key of this node

value - the value of this node

Method Detail

getKey

public K getKey()

Gets the key.

Specified by:

getKey in interface KeyValue<K extends Comparable<K>,V extends Comparable<V>>

Specified by:

getKey in interface Map.Entry<K extends Comparable<K>,V extends Comparable<V>>

Returns:

the key corresponding to this entry.

getValue

public V getValue()

Gets the value.

Specified by:

getValue in interface KeyValue<K extends Comparable<K>,V extends Comparable<V>>

Specified by:

getValue in interface Map.Entry<K extends Comparable<K>,V extends Comparable<V>>

Returns:

the value corresponding to this entry.

setValue

public V setValue(V ignored)
           throws UnsupportedOperationException

Optional operation that is not permitted in this implementation

Specified by:

setValue in interface Map.Entry<K extends Comparable<K>,V extends Comparable<V>>

Parameters:

ignored - this parameter is ignored.

Returns:

does not return

Throws:

UnsupportedOperationException - always

equals

public boolean equals(Object obj)

Compares the specified object with this entry for equality. Returns true if the given object is also a map entry and the two entries represent the same mapping.

Specified by:

equals in interface Map.Entry<K extends Comparable<K>,V extends Comparable<V>>

Overrides:

equals in class Object

Parameters:

obj - the object to be compared for equality with this entry.

Returns:

true if the specified object is equal to this entry.

hashCode

public int hashCode()

Specified by:

hashCode in interface Map.Entry<K extends Comparable<K>,V extends Comparable<V>>

Overrides:

hashCode in class Object

Returns:

the hash code value for this map entry.
