Method Detail
-
getKey
public java.lang.Object getKey()
- Specified by:
getKeyin interfacejava.util.Map.Entry
-
getValue
public java.lang.Object getValue()
Get the value. Note: In an entrySet or entrySet.iterator, unless the set or iterator is used under synchronization of the table as a whole (or you can otherwise guarantee lack of concurrent modification), getValue might return null, reflecting the fact that the entry has been concurrently removed. However, there are no assurances that concurrent removals will be reflected using this method.- Specified by:
getValuein interfacejava.util.Map.Entry- Returns:
- the current value, or null if the entry has been detectably removed.
-
setValue
public java.lang.Object setValue(java.lang.Object value)
Set the value of this entry. Note: In an entrySet or entrySet.iterator), unless the set or iterator is used under synchronization of the table as a whole (or you can otherwise guarantee lack of concurrent modification), setValue is not strictly guaranteed to actually replace the value field obtained via the get operation of the underlying hash table in multi-threaded applications. If iterator-wide synchronization is not used, and any other concurrent put or remove operations occur, sometimes even to other entries, then this change is not guaranteed to be reflected in the hash table. (It might, or it might not. There are no assurances either way.)- Specified by:
setValuein interfacejava.util.Map.Entry- Parameters:
value- the new value.- Returns:
- the previous value, or null if entry has been detectably removed.
- Throws:
java.lang.NullPointerException- if the value isnull.
