Method Detail

comparator

public LongComparator comparator()
Description copied from interface: Long2ObjectSortedMap
Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Note that this specification strengthens the one given in SortedMap.comparator().

Specified by:
comparator in interface Long2ObjectSortedMap<V>
Specified by:
comparator in interface java.util.SortedMap<java.lang.Long,V>
See Also:
SortedMap.comparator()

long2ObjectEntrySet

public ObjectSortedSet<Long2ObjectMap.Entry<V>> long2ObjectEntrySet()
Description copied from interface: Long2ObjectMap
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 Long2ObjectMap.entrySet() so that it returns an ObjectSet of objects of type Long2ObjectMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
long2ObjectEntrySet in interface Long2ObjectMap<V>
Specified by:
long2ObjectEntrySet in interface Long2ObjectSortedMap<V>
Overrides:
long2ObjectEntrySet in class Long2ObjectMaps.EmptyMap<V>
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Long2ObjectMap.entrySet()

entrySet

public ObjectSortedSet<java.util.Map.Entry<java.lang.Long,V>> entrySet()
Description copied from interface: Long2ObjectMap
Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:
entrySet in interface Long2ObjectMap<V>
Specified by:
entrySet in interface Long2ObjectSortedMap<V>
Specified by:
entrySet in interface java.util.Map<java.lang.Long,V>
Overrides:
entrySet in class Long2ObjectMaps.EmptyMap<V>
Returns:
a set view of the mappings contained in this map.
See Also:
Map.entrySet()

keySet

public LongSortedSet keySet()
Description copied from interface: Long2ObjectMap
Returns a set view of the keys contained in this map.

Note that this specification strengthens the one given in Map.keySet().

Specified by:
keySet in interface Long2ObjectMap<V>
Specified by:
keySet in interface Long2ObjectSortedMap<V>
Specified by:
keySet in interface java.util.Map<java.lang.Long,V>
Overrides:
keySet in class Long2ObjectMaps.EmptyMap<V>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

subMap

public Long2ObjectSortedMap<V> subMap(long from,
                                      long to)
Description copied from interface: Long2ObjectSortedMap
Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

SortedMap.subMap(Object,Object)

headMap

public Long2ObjectSortedMap<V> headMap(long to)
Description copied from interface: Long2ObjectSortedMap
Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

SortedMap.headMap(Object)

tailMap

public Long2ObjectSortedMap<V> tailMap(long from)
Description copied from interface: Long2ObjectSortedMap

headMap

public Long2ObjectSortedMap<V> headMap(java.lang.Long oto)
Description copied from interface: Long2ObjectSortedMap
Returns a view of the portion of this sorted map whose keys are strictly less than toKey.
