Method Details
-
getKey
Description copied from interface:MapIteratorGets the current key, which is the key returned by the last call tonext().- Specified by:
getKeyin interfaceMapIterator<K,V> - Returns:
- the current key
-
getValue
Description copied from interface:MapIteratorGets the current value, which is the value associated with the last key returned bynext().- Specified by:
getValuein interfaceMapIterator<K,V> - Returns:
- the current value
-
hasNext
Description copied from interface:MapIteratorChecks to see if there are more entries still to be iterated. -
hasPrevious
Description copied from interface:OrderedMapIteratorChecks to see if there is a previous entry that can be iterated to.- Specified by:
hasPreviousin interfaceOrderedIterator<K>- Specified by:
hasPreviousin interfaceOrderedMapIterator<K,V> - Returns:
trueif the iterator has a previous element
-
next
Description copied from interface:MapIteratorGets the next key from theMap. -
previous
Description copied from interface:OrderedMapIteratorGets the previous key from theMap.- Specified by:
previousin interfaceOrderedIterator<K>- Specified by:
previousin interfaceOrderedMapIterator<K,V> - Returns:
- the previous key in the iteration
-
remove
Description copied from interface:MapIteratorRemoves the last returned key from the underlyingMap(optional operation).This method can be called once per call to
next(). -
reset
Description copied from interface:ResettableIteratorResets the iterator back to the position at which the iterator was created.- Specified by:
resetin interfaceResettableIterator<K>
-
setValue
Description copied from interface:MapIteratorSets the value associated with the current key (optional operation).- Specified by:
setValuein interfaceMapIterator<K,V> - Parameters:
value- the new value- Returns:
- the previous value
-
toString
