Class Entry<V,K>

java.lang.Object
  info.monitorenter.util.collections.Entry<V,K>

Type Parameters:

V - the key type.

K - the value type.

All Implemented Interfaces:

java.util.Map.Entry<V,K>

public final class Entry<V,K>
extends java.lang.Object
implements java.util.Map.Entry<V,K>

I have written implementations of java.util.Map.Entry in form of

• Static inner classes.
• Non-static inner classes.
• Non-public classes.
• Anonymous classes.

Almost all implementations were plainforward and not hiding any complexity. One could not downcast them to get more methods, and they were replaceable.
That's it! Finally i decided to hardcode it here... .

But don't you start writing methods like:

 public Entry getEntry(String name);
 
 public void setEntry(Entry entry);
 

Try sticking to the interface java.util.Map.Entry.
