returned by
next() . |
boolean |
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()
Gets the previous key from the
Map . |
void |
remove()
