to
next() . |
protected OrderedMapIterator<K,V> |
getOrderedMapIterator()

|
V |
getValue()
Gets the current value, which is the value associated with the last key
returned by
next() . |

hasNext()
Checks to see if there are more entries still to be iterated.
|
boolean |
hasPrevious()
Checks to see if there is a previous entry that can be iterated to.
|
K |
next()
Gets the next key from the
Map . |
K |
previous()
