EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap.Entry
- ConcurrentReaderHashMap
- Map.Entry
protected static class ConcurrentReaderHashMap.Entry
extends java.lang.Object
implements Map.Entry
ConcurrentReaderHashMap collision list entry.
hash
protected final int hash
key
protected final Object key
value
protected Object value
equals
public boolean equals(Object o)
getKey
public Object getKey()
getValue
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.
- the current value, or null if the entry has been
detectably removed.
hashCode
public int hashCode()
setValue
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.)
- the previous value, or null if entry has been detectably
removed.
toString
public String toString()
