Constructor Detail

ConcurrentReaderHashMap.Entry

ConcurrentReaderHashMap.Entry(int hash,
                              java.lang.Object key,
                              java.lang.Object value,
                              ConcurrentReaderHashMap.Entry next)

Method Detail

getKey

public java.lang.Object getKey()

Description copied from interface: java.util.Map.Entry

Get the key corresponding to this entry.

Specified by:

getKey in interface java.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:

getValue in interface java.util.Map.Entry

---

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

---

equals

public boolean equals(java.lang.Object o)

Description copied from interface: java.util.Map.Entry

Compares the specified object with this entry. Returns true only if the object is a mapping of identical key and value. In other words, this must be:

(o instanceof Map.Entry)
&& (getKey() == null ? ((Map.Entry) o).getKey() == null
                     : getKey().equals(((Map.Entry) o).getKey()))
&& (getValue() == null ? ((Map.Entry) o).getValue() == null
                       : getValue().equals(((Map.Entry) o).getValue()))

Specified by:

equals in interface java.util.Map.Entry

---

hashCode

public int hashCode()

Description copied from interface: java.util.Map.Entry

Returns the hash code of the entry. This is defined as the exclusive-or of the hashcodes of the key and value (using 0 for null). In other words, this must be:

(getKey() == null ? 0 : getKey().hashCode())
^ (getValue() == null ? 0 : getValue().hashCode())

Specified by:

hashCode in interface java.util.Map.Entry

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
