Modifier and Type | Method and Description |
---|---|
K |
getKey()
Gets the current key, which is the key returned by the last call
to
next() . |
V |
getValue()
Gets the current value, which is the value associated with the last key
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()
Removes the last returned key from the underlying
Map (optional operation). |
V |
setValue(V value)
Sets the value associated with the current key (optional operation).
