getDelegate() Return the Map to which all operations should be delegated to. |
Object |
getKey() Returns the key corresponding to this entry. |
Object |
getValue() Returns the value corresponding to this entry. |
int |
hashCode() Returns the hash code value for this map entry. |

oValue
- new value to be stored in this entry.public boolean equals(Object o)
(e1.getKey()==null ? e2.getKey()==null : e1.getKey().equals(e2.getKey())) && (e1.getValue()==null ? e2.getValue()==null : e1.getValue().equals(e2.getValue()))This ensures that the equals method works properly across different implementations of the Map.Entry interface.
equals
in interface Map.Entry
o
- object to be compared for equality with this map entry.public int hashCode()
(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.

Object.hashCode()
, Object.equals(Object)
