Class Entry

java.lang.Object
  info.monitorenter.util.collections.Entry

All Implemented Interfaces:

Map.Entry

public final class Entry
extends Object
implements Map.Entry

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.
