Class ConcurrentReaderHashMap.Entry
java.lang.Object
org.dom4j.tree.ConcurrentReaderHashMap.Entry
- All Implemented Interfaces:
- Map.Entry
- Enclosing class:
- org.dom4j.tree.ConcurrentReaderHashMap
- protected static class ConcurrentReaderHashMap.Entry
- extends Object
- implements Map.Entry
ConcurrentReaderHashMap collision list entry.
hash
protected final int hash
key
protected final Object key
next
protected final ConcurrentReaderHashMap.Entry next
value
protected volatile Object value
getKey
public Object getKey()
- Specified by:
getKey
in interface Map.Entry
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.
- Specified by:
getValue
in interface Map.Entry
- Returns:
- the current value, or null if the entry has been detectably
removed.
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.)
- Specified by:
setValue
in interface Map.Entry
- Parameters:
value
- the new value.
- Returns:
- the previous value, or null if entry has been detectably
removed.
- Throws:
NullPointerException
- if the value is null
.
equals
public boolean equals(Object o)
- Specified by:
equals
in interface Map.Entry
hashCode
public int hashCode()
- Specified by:
hashCode
in interface Map.Entry
toString
public String toString()
