Method Summary

Modifier and Type	Method	Description
void	clear()
C	get(K key)	Returns a view of all values associated with the given key.
C	getIfAbsentPutAll(K key, Iterable<? extends V> values)	Puts values into multimap if there are no values already associated with key.
boolean	isEmpty()	Returns true if there are no entries.
SetIterable<K>	keySet()	Returns a unmodifiable SetIterable of keys with O(1) complexity.
boolean	put(K key, V value)
boolean	putAll(K key, Iterable<? extends V> values)
<KK extends K, VV extends V> boolean	putAll(Multimap<KK,VV> multimap)
void	readExternal(ObjectInput in)
boolean	remove(Object key, Object value)
C	removeAll(Object key)
C	replaceValues(K key, Iterable<? extends V> values)
int	size()	Use the size method directly instead of totalSize internally so subclasses can override if necessary.
int	sizeDistinct()	Returns the number of distinct keys.
MutableMap<K,RichIterable<V>>	toMap()	Returns a new MutableMap of keys from this Multimap to the mapped values as a RichIterable.
<R extends Collection<V>> MutableMap<K,R>	toMap(Function0<R> collectionFactory)	Returns a new MutableMap of keys from this Multimap to the mapped values as a RichIterable.

Method Details

size

public int size()

Use the size method directly instead of totalSize internally so subclasses can override if necessary.

Specified by:

size in interface Multimap<K,V>

sizeDistinct

public int sizeDistinct()

Description copied from interface: Multimap

Returns the number of distinct keys.

Specified by:

sizeDistinct in interface Multimap<K,V>

isEmpty

public boolean isEmpty()

Description copied from interface: Multimap

Returns true if there are no entries.

Specified by:

isEmpty in interface Multimap<K,V>

put

public boolean put(K key, V value)

Specified by:

put in interface MutableMultimap<K,V>

remove

public boolean remove(Object key, Object value)

Specified by:

remove in interface MutableMultimap<K,V>

putAll

public boolean putAll(K key, Iterable<? extends V> values)

Specified by:

putAll in interface MutableMultimap<K,V>

putAll

public <KK extends K, VV extends V> boolean putAll(Multimap<KK,VV> multimap)

Specified by:

putAll in interface MutableMultimap<K,V>

replaceValues

public C replaceValues(K key, Iterable<? extends V> values)

Specified by:

replaceValues in interface MutableMultimap<K,V>

removeAll

public C removeAll(Object key)

Specified by:

removeAll in interface MutableMultimap<K,V>

clear

public void clear()

Specified by:

clear in interface MutableMultimap<K,V>

keySet

public SetIterable<K> keySet()

Description copied from interface: Multimap

Returns a unmodifiable SetIterable of keys with O(1) complexity.

Specified by:

keySet in interface Multimap<K,V>

get

public C get(K key)

Description copied from interface: Multimap

Returns a view of all values associated with the given key.

If the given key does not exist, an empty RichIterable is returned.

Specified by:

get in interface Multimap<K,V>

Specified by:

get in interface MutableMultimap<K,V>

Parameters:

key - the key to search for

getIfAbsentPutAll

public C getIfAbsentPutAll(K key, Iterable<? extends V> values)

Description copied from interface: MutableMultimap

Puts values into multimap if there are no values already associated with key. Then returns a view of the values associated with key, like the result of Multimap.get(Object)

Specified by:

getIfAbsentPutAll in interface MutableMultimap<K,V>

toMap

public MutableMap<K,RichIterable<V>> toMap()

Description copied from interface: Multimap

Returns a new MutableMap of keys from this Multimap to the mapped values as a RichIterable.

Specified by:

toMap in interface Multimap<K,V>

toMap

public <R extends Collection<V>> MutableMap<K,R> toMap(Function0<R> collectionFactory)

Description copied from interface: Multimap

Returns a new MutableMap of keys from this Multimap to the mapped values as a RichIterable.

Specified by:

toMap in interface Multimap<K,V>

Parameters:

collectionFactory - used to create the collections that hold the values and affects the return type

writeExternal

public void writeExternal(ObjectOutput out) throws IOException

Throws:

IOException

readExternal

public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException

Throws:

IOException

ClassNotFoundException
