MapSecondary

public MapSecondary()

Method Details

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

replaceValue

public V replaceValue(K key,
 V value)

Description copied from interface: Map

Replaces the value associated with key in this with value and returns the old value.

Specified by:

replaceValue in interface Map<K,V>

Parameters:

key - the key whose associated value is replaced

value - the value replacing the old one

Returns:

the old value associated with the given key

key

public K key(V value)

Description copied from interface: Map

Reports a key associated with value in this. Note that the key returned generally should not be changed at all via this aliased reference, and if it is then it definitely must not be changed in such a way that it equals another key in the map from which it was obtained.

Specified by:

key in interface Map<K,V>

Parameters:

value - the value whose associated key is to be reported

Returns:

a key associated with value

hasValue

public boolean hasValue(V value)

Description copied from interface: Map

Reports whether there is a pair in this whose second component is value.

Specified by:

hasValue in interface Map<K,V>

Parameters:

value - the value to be checked

Returns:

true iff there is a pair in this whose second component is value

sharesKeyWith

public boolean sharesKeyWith(Map<K,V> m)

Description copied from interface: Map

Reports whether this and m have any keys in common.

Specified by:

sharesKeyWith in interface Map<K,V>

Parameters:

m - the Map to be checked against this

Returns:

true iff there are keys in common

combineWith

public void combineWith(Map<K,V> m)

Description copied from interface: Map

Combines m with this.

Specified by:

combineWith in interface Map<K,V>

Parameters:

m - the Map to be combined with this
