The cached hash code of the key.

key

protected K key

The key.

value

protected V value

The value.

Constructor Detail

BasicEMap.EntryImpl

public BasicEMap.EntryImpl(int hash,
                           K key,
                           V value)

Creates a fully initialized instance.

Parameters:

hash - the hash code of the key.

key - the key.

value - the value.

Method Detail

clone

protected java.lang.Object clone()

Returns a new entry just like this one.

Overrides:

clone in class java.lang.Object

Returns:

a new entry just like this one.

getHash

public int getHash()

Description copied from interface: BasicEMap.Entry

Returns the hash code of the key. Only the map implementation would really care.

Specified by:

getHash in interface BasicEMap.Entry<K,V>

setHash

public void setHash(int hash)

Description copied from interface: BasicEMap.Entry

Sets the hash code of the key. This should only be called by the map implementation, since the hash code of the key of an entry already in the map must be immutable.

Specified by:

setHash in interface BasicEMap.Entry<K,V>

Parameters:

hash - the hash.

getKey

public K getKey()

Specified by:

getKey in interface java.util.Map.Entry<K,V>

setKey

public void setKey(K key)

Description copied from interface: BasicEMap.Entry

Sets the key. This should only be called by the map implementation, since the key of an entry already in the map must be immutable.

Specified by:

setKey in interface BasicEMap.Entry<K,V>

Parameters:

key - the key.

getValue

public V getValue()

Specified by:

getValue in interface java.util.Map.Entry<K,V>

setValue

public V setValue(V value)

Specified by:

setValue in interface java.util.Map.Entry<K,V>

equals

public boolean equals(java.lang.Object object)

Specified by:

equals in interface java.util.Map.Entry<K,V>

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Specified by:

hashCode in interface java.util.Map.Entry<K,V>

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
