Method Details

containsValue

public boolean containsValue(Object v)

Specified by:

containsValue in interface Map<K,V>

putAll

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

Specified by:

putAll in interface Map<K,V>

object2ObjectEntrySet

public ObjectSet<Object2ObjectMap.Entry<K,V>> object2ObjectEntrySet()

Description copied from interface: Object2ObjectMap

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

object2ObjectEntrySet in interface Object2ObjectMap<K,V>

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Map.entrySet()

entrySet

public ObjectSet<Map.Entry<K,V>> entrySet()

Returns a set view of the mappings contained in this map.

Specified by:

entrySet in interface Map<K,V>

Specified by:

entrySet in interface Object2ObjectMap<K,V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ObjectSet<K> keySet()

Description copied from interface: Object2ObjectMap

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface Object2ObjectMap<K,V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ObjectCollection<V> values()

Description copied from interface: Object2ObjectMap

Specified by:

values in interface Map<K,V>

Specified by:

values in interface Object2ObjectMap<K,V>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<K,V>

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<K,V>

Overrides:

equals

public boolean equals(Object o)

Specified by:

Overrides:

equals in class Object2ObjectFunctions.UnmodifiableFunction<K,V>

getOrDefault

public V getOrDefault(Object key,
V defaultValue)

Description copied from interface: Object2ObjectFunction

Specified by:

getOrDefault in interface Map<K,V>

Specified by:

getOrDefault in interface Object2ObjectFunction<K,V>

Specified by:

getOrDefault in interface Object2ObjectMap<K,V>

Overrides:

getOrDefault in class Object2ObjectFunctions.UnmodifiableFunction<K,V>

Parameters:

key - the key.

defaultValue - the value to return if not present.

Returns:

the corresponding value, or defaultValue if no value was present for the given key.
