Constructor Detail

AbstractKeySetBasedMap.KeyIterator

protected AbstractKeySetBasedMap.KeyIterator(java.util.Iterator 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(java.lang.Object) if there is a next object.

Specified by:
advance in class AbstractStableIterator

remove

protected void remove(java.lang.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 AbstractStableIterator
Parameters:
oPrev - the previously iterated object that should be removed
