Constructor Details

UnmodifiableMap

UnmodifiableMap(CharObjectMap<V> map)

Method Details

get

public V get(char key)

Description copied from interface: CharObjectMap

Gets the value in the map with the specified key.

Specified by:

get in interface CharObjectMap<V>

Parameters:

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

Returns:

the value or null if the key was not found in the map.

put

public V put(char key,
 V value)

Description copied from interface: CharObjectMap

Puts the given entry into the map.

Specified by:

put in interface CharObjectMap<V>

Parameters:

key - the key of the entry.

value - the value of the entry.

Returns:

the previous value for this key or null if there was no previous mapping.

remove

public V remove(char key)

Description copied from interface: CharObjectMap

Removes the entry with the specified key.

Specified by:

remove in interface CharObjectMap<V>

Parameters:

key - the key for the entry to be removed from this map.

Returns:

the previous value for the key, or null if there was no mapping.

size

public int size()

Specified by:

size in interface Map<Character, V>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Character, V>

clear

public void clear()

Specified by:

clear in interface Map<Character, V>

containsKey

public boolean containsKey(char key)

Description copied from interface: CharObjectMap

Indicates whether or not this map contains a value for the specified key.

Specified by:

containsKey in interface CharObjectMap<V>

containsValue

public boolean containsValue(Object value)

Specified by:

containsValue in interface Map<Character, V>

containsKey

public boolean containsKey(Object key)

Specified by:

containsKey in interface Map<Character, V>

get

public V get(Object key)

Specified by:

get in interface Map<Character, V>

put

public V put(Character key,
 V value)

Specified by:

put in interface Map<Character, V>

remove

public V remove(Object key)

Specified by:

remove in interface Map<Character, V>

putAll

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

Specified by:

putAll in interface Map<Character, V>

entries

public Iterable<CharObjectMap.PrimitiveEntry<V>> entries()

Description copied from interface: CharObjectMap

Gets an iterable to traverse over the primitive entries contained in this map. As an optimization, the CharObjectMap.PrimitiveEntrys returned by the

invalid reference

Iterator

may change as the

invalid reference

Iterator

progresses. The caller should not rely on CharObjectMap.PrimitiveEntry key/value stability.

Specified by:

entries in interface CharObjectMap<V>

keySet

public Set<Character> keySet()

Specified by:

keySet in interface Map<Character, V>

entrySet

public Set<Map.Entry<Character, V>> entrySet()

Specified by:

entrySet in interface Map<Character, V>

values

public Collection<V> values()

Specified by:

values in interface Map<Character, V>
