- Constructor Detail
  - KeyIterator
```
protected KeyIterator(Iterator<K> iter)
```
    Construct a KeyIterator.
    
    Parameters:
    
    iter - the underlying Iterator from the internal key Set
- Method Detail
  - advance
```
protected void advance()
```
    Advance to the next object.
    This method must be implemented by the concrete sub-class by calling AbstractStableIterator.setNext(T) if there is a next object.
    
    Specified by:
    
    advance in class com.oracle.coherence.common.collections.AbstractStableIterator<K>
  - remove
```
protected void remove(Object oPrev)
```
    Remove the specified item.
    This is an optional operation. If the Iterator supports element removal, then it should implement this method, which is delegated to by the AbstractStableIterator.remove() method.
    
    Overrides:
    
    remove in class com.oracle.coherence.common.collections.AbstractStableIterator<K>
    
    Parameters:
    
    oPrev - the previously iterated object that should be removed
