Method Detail

decorate

public static OrderedMap decorate(OrderedMap map)

Deprecated.

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

public MapIterator mapIterator()

Deprecated.

Description copied from interface: IterableMap

Obtains a MapIterator over 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:

mapIterator in interface IterableMap

Overrides:

mapIterator in class AbstractOrderedMapDecorator

Returns:

a map iterator

orderedMapIterator

public OrderedMapIterator orderedMapIterator()

Deprecated.

Description copied from interface: OrderedMap

Obtains an OrderedMapIterator over 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();
 }
