[Java] Class ConcurrentReaderHashMap.Entry

java.lang.Object
  org.codehaus.groovy.runtime.metaclass.ConcurrentReaderHashMap.Entry

All Implemented Interfaces:

Entry

protected static class ConcurrentReaderHashMap.Entry

ConcurrentReaderHashMap collision list entry.

hash

protected final int hash

key

protected final Object key

next

protected final Entry next

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.

Returns:

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.)

Throws:

NullPointerException if the value is null.

Parameters:

value - the new value.

Returns:

the previous value, or null if entry has been detectably removed.

toString

public String toString()
