Enclosing class:

AbstractKeyBasedMap.EntrySet

protected class AbstractKeyBasedMap.EntrySet.Entry
extends SimpleMapEntry<K,V>

A Map Entry implementation that defers its value acquisition from the containing map (via Map.get(Object)) if the Entry is constructed with a null value.

Constructor Detail

Entry

public Entry(K oKey,
             V oValue)

Construct an Entry.

Parameters:

oKey - the Entry key

oValue - the Entry value (optional)

Method Detail

getValue

public V getValue()

Returns the value corresponding to this entry.

Specified by:

getValue in interface InvocableMap.Entry<K,V>

Specified by:

getValue in interface Map.Entry<K,V>

Overrides:

getValue in class SimpleMapEntry<K,V>

Returns:

the value corresponding to this entry

setValue

public V setValue(V oValue)

Replaces the value corresponding to this entry with the specified value (optional operation). (Writes through to the map.)

Specified by:

setValue in interface InvocableMap.Entry<K,V>

Specified by:

setValue in interface Map.Entry<K,V>

Overrides:

setValue in class SimpleMapEntry<K,V>

Parameters:

oValue - new value to be stored in this entry

Returns:

old value corresponding to the entry

hashCode

public int hashCode()

Returns the hash code value for this map entry. The hash code of a map entry e is defined to be:

     (e.getKey()==null   ? 0 : e.getKey().hashCode()) ^
     (e.getValue()==null ? 0 : e.getValue().hashCode())
 

This ensures that e1.equals(e2) implies that e1.hashCode()==e2.hashCode() for any two Entries e1 and e2, as required by the general contract of Object.hashCode.

Specified by:

hashCode in interface Map.Entry<K,V>

Overrides:

hashCode in class SimpleMapEntry<K,V>

Returns:

the hash code value for this map entry.
