Package org.forgerock.http.util

Class CaseInsensitiveMap<V>

java.lang.Object

org.forgerock.util.MapDecorator<String,V>

org.forgerock.http.util.CaseInsensitiveMap<V>

Type Parameters:

V - The type of the case insensitive map.

All Implemented Interfaces:

Map<String,V>

public class CaseInsensitiveMap<V>
extends MapDecorator<String,V>

An implementation of a map whose keys are case-insensitive strings. All operations match keys in a case-insensitive manner. The original cases of keys are retained, so the keySet() method for example returns the original keys.

Note: The behavior of this class is undefined when wrapping a map that has keys that would result in duplicate case-insensitive keys.

Constructor Detail

CaseInsensitiveMap

public CaseInsensitiveMap()

Constructs a new empty case-insensitive map. The backing map is a new HashMap with default initial capacity and load factor.

CaseInsensitiveMap

public CaseInsensitiveMap(Map<String,V> map)

Wraps an existing map with a new case insensitive map.

Parameters:

map - the map to wrap with a new case insensitive map.

Method Detail

sync

public void sync()

Synchronizes the keys of this case insensitive map and those of the map it is wrapping. This is necessary if the underlying map is modified directly and this map needs to be resynchronized.

clear

public void clear()

Description copied from class: MapDecorator

Removes all of the mappings from the map.

Specified by:

clear in interface Map<String,V>

Overrides:

clear in class MapDecorator<String,V>

containsKey

public boolean containsKey(Object key)

Description copied from class: MapDecorator

Returns true if this map contains a mapping for the specified key.

Specified by:

containsKey in interface Map<String,V>

Overrides:

containsKey in class MapDecorator<String,V>

Parameters:

key - the key whose presence in this map is to be tested.

Returns:

true if this map contains a mapping for the specified key.

put

public V put(String key,
             V value)

Description copied from class: MapDecorator

Associates the specified value with the specified key in the map.

Specified by:

put in interface Map<String,V>

Overrides:

put in class MapDecorator<String,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, or null if no mapping.

putAll

public void putAll(Map<? extends String,? extends V> m)

Description copied from class: MapDecorator

Copies all of the mappings from the specified map to the map.

Specified by:

putAll in interface Map<String,V>

Overrides:

putAll in class MapDecorator<String,V>

Parameters:

m - mappings to be stored in the map.

get

public V get(Object key)

Description copied from class: MapDecorator

Returns the value to which the specified key is mapped, or null if the map contains no mapping for the key.

Specified by:

get in interface Map<String,V>

Overrides:

get in class MapDecorator<String,V>

Parameters:

key - the key whose associated value is to be returned.

Returns:

the value to which the specified key is mapped, or null if no mapping.

remove

public V remove(Object key)

Description copied from class: MapDecorator

Removes the mapping for a key from the map if it is present.

Specified by:

remove in interface Map<String,V>

Overrides:

remove in class MapDecorator<String,V>

Parameters:

key - key whose mapping is to be removed from the map.

Returns:

the previous value associated with key, or null if no mapping.
