getKey
public java.lang.Object getKey()
- Specified by:
getKey
in interface java.util.Map.Entry
- See Also:
getKey()
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:
getValue
in interface java.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 multithreaded 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:
setValue
in interface java.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 is null
.
