Field Detail

cursor

protected int cursor
The cursor in the entry data.


entryCursor

protected int entryCursor
The cursor in the list of entries.


lastCursor

protected int lastCursor
The last cursor in the entry data.


lastEntryCursor

protected int lastEntryCursor
The cursor in the list of entries.


expectedModCount

protected int expectedModCount
The modification count expected of the map.

Method Detail

yield

protected U yield(BasicEMap.Entry<K,V> entry)
Called to yield the iterator result for the entry. This implementation returns the entry itself.

Parameters:
entry - the entry.
Returns:
the iterator result for the entry.

scan

protected void scan()
Scans to the new entry.


hasNext

public boolean hasNext()
Returns whether there are more objects.

Specified by:
hasNext in interface java.util.Iterator<U>
Returns:
whether there are more objects.

next

public U next()
Returns the next object and advances the iterator.

Specified by:
next in interface java.util.Iterator<U>
Returns:
the next object.
Throws:
java.util.NoSuchElementException - if the iterator is done.

remove

public void remove()
Removes the entry of the last object returned by next() from the map, it's an optional operation.

Specified by:
remove in interface java.util.Iterator<U>
Throws:
java.lang.IllegalStateException - if next has not yet been called, or remove has already been called after the last call to next.
