class
ConcurrentReaderHashMap.Entry
extends Object
implements Entry
ConcurrentReaderHashMap collision list entry.
protected final int hash
protected final Object key
protected volatile Object value
public boolean equals(Object o)
public Object getKey()
public 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.
Returns: the current value, or null if the entry has been detectably
removed.
public int hashCode()
public Object setValue(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.)
Parameters: value
the new value.
Returns: the previous value, or null if entry has been detectably
removed.
Throws: NullPointerException
if the value is null
.
