org.apache.commons.collections4.map.UnmodifiableOrderedMap<K,V> 
- Type Parameters:
- K- the type of the keys in this map
- V- the type of the values in this map
- All Implemented Interfaces:
- Serializable,- Map<K,,- V> - Get<K,,- V> - IterableGet<K,,- V> - IterableMap<K,,- V> - OrderedMap<K,,- V> - Put<K,,- V> - Unmodifiable
public final class UnmodifiableOrderedMap<K,V> 
extends AbstractOrderedMapDecorator<K,V>
implements Unmodifiable, Serializable 
Decorates another 
OrderedMap to ensure it can't be altered.
 This class is Serializable from Commons Collections 3.1.
Attempts to modify it will result in an UnsupportedOperationException.

Method Details- 
unmodifiableOrderedMappublic static <K,V> OrderedMap<K,V> unmodifiableOrderedMap(OrderedMap<? extends K, ? extends V> map) Factory method to create an unmodifiable sorted map.- Type Parameters:

entrySetDescription copied from interface:GetGets a set view of the mappings contained in this map.
- 
keySetDescription copied from interface:GetGets a view of the keys contained in this map.
- 
mapIteratorDescription copied from class:AbstractIterableMapObtains aMapIteratorover the map.A map iterator is an efficient way of iterating over maps. There is no need to access the entry set or use Map Entry objects. IterableMap<String,Integer> map = new HashedMap<String,Integer>(); MapIterator<String,Integer> it = map.mapIterator(); while (it.hasNext()) { String key = it.next(); Integer value = it.getValue(); it.setValue(value + 1); }- Specified by:
- mapIteratorin interface- IterableGet<K,- V> 
- Specified by:
- mapIteratorin interface- OrderedMap<K,- V> 
- Overrides:
- mapIteratorin class- AbstractOrderedMapDecorator<K,- V> 
- Returns:
- a map iterator
 
- 
putDescription copied from interface:PutAssociates the specified value with the specified key in this map.Note that the return type is Object, rather than V as in the Map interface. See the class Javadoc for further info. - Specified by:
- putin interface- Map<K,- V> 
- Specified by:
- putin interface- Put<K,- V> 
- Overrides:
- putin class- AbstractMapDecorator<K,- V> 
- Parameters:
- key- key with which the specified value is to be associated
- value- value to be associated with the specified key
- Returns:
- the previous value associated with key, ornullif there was no mapping forkey. (Anullreturn can also indicate that the map previously associatednullwithkey, if the implementation supportsnullvalues.)

putAllDescription copied from interface:PutCopies all of the mappings from the specified map to this map.
- 
removeDescription copied from interface:GetRemove a key-value mappings.- Specified by:
- removein interface- Get<K,- V> 
- Specified by:
- removein interface- Map<K,- V> 
- Overrides:
- removein class- AbstractMapDecorator<K,- V> 
- Parameters:
- key- key whose mapping is to be removed from the map
- Returns:
- the previous value associated with key, ornullif there was no mapping forkey.

valuesDescription copied from interface:GetGets a a collection view of the values contained in this map.
