Method Details
-
decorate
Factory method to create an unmodifiable sorted map.- Parameters:
map- the map to decorate, must not be null- Throws:
IllegalArgumentException- if map is null
-
mapIterator
Description copied from interface:IterableMapObtains aMapIteratorover the map.A map iterator is an efficient way of iterating over maps. There is no need to access the entry set or cast to Map Entry objects.
IterableMap map = new HashedMap(); MapIterator it = map.mapIterator(); while (it.hasNext()) { Object key = it.next(); Object value = it.getValue(); it.setValue("newValue"); }- Specified by:
mapIteratorin interfaceIterableMap- Overrides:
mapIteratorin classAbstractOrderedMapDecorator- Returns:
- a map iterator
-
orderedMapIterator
Description copied from interface:OrderedMapObtains anOrderedMapIteratorover the map.A ordered map iterator is an efficient way of iterating over maps in both directions.
BidiMap map = new TreeBidiMap(); MapIterator it = map.mapIterator(); while (it.hasNext()) { Object key = it.next(); Object value = it.getValue(); it.setValue("newValue"); Object previousKey = it.previous(); }- Specified by:

- a map iterator
