Constructor Detail

AbstractKeyBasedMap.EntrySet.Entry

public AbstractKeyBasedMap.EntrySet.Entry(java.lang.Object oKey,
                                          java.lang.Object oValue)
Construct an Entry.
Parameters:
oKey - the Entry key
oValue - the Entry value (optional)

Method Detail

getValue

public java.lang.Object getValue()
Returns the value corresponding to this entry.
Specified by:
getValue in interface InvocableMap.Entry
Specified by:
getValue in interface java.util.Map.Entry
Overrides:
getValue in class SimpleMapEntry
Returns:
the value corresponding to this entry

setValue

public java.lang.Object setValue(java.lang.Object 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
Specified by:
setValue in interface java.util.Map.Entry
Overrides:
setValue in class SimpleMapEntry
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 java.util.Map.Entry
Overrides:
hashCode in class SimpleMapEntry
Returns:
the hash code value for this map entry.
See Also:
Object.hashCode(), Object.equals(Object), Map.Entry.equals(Object)
