nextEntry(boolean fSynthetic) Get the next entry in the linked list (open hash). |
protected void |
setNext(SegmentedHashMap.Entry eNext) Set the next entry in the linked list (open hash) |
java.lang.Object |
setValue(java.lang.Object oValue) Replaces the value corresponding to this entry with the specified value (writes through to the map). |
protected java.lang.Object |
setValueInternal(java.lang.Object oValue) Replaces the value corresponding to this entry with the specified value (writes through to the map). |
java.lang.String |

(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.

(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.
