Method Detail

comparator

public java.util.Comparator<? super K> comparator()

Description copied from interface: Object2LongSortedMap

Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Specified by:

comparator in interface Object2LongSortedMap<K>

Specified by:

comparator in interface java.util.SortedMap<K,java.lang.Long>

See Also:

SortedMap.comparator()

object2LongEntrySet

public it.unimi.dsi.fastutil.objects.ObjectSortedSet<Object2LongMap.Entry<K>> object2LongEntrySet()

Description copied from interface: Object2LongMap

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:

object2LongEntrySet in interface Object2LongMap<K>

Specified by:

object2LongEntrySet in interface Object2LongSortedMap<K>

Overrides:

object2LongEntrySet in class Object2LongMaps.EmptyMap<K>

Returns:

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

See Also:

Map.entrySet()

entrySet

@Deprecated
public it.unimi.dsi.fastutil.objects.ObjectSortedSet<java.util.Map.Entry<K,java.lang.Long>> entrySet()

Deprecated. Please use the corresponding type-specific method instead.

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

Specified by:

entrySet in interface Object2LongMap<K>

Specified by:

entrySet in interface Object2LongSortedMap<K>

Specified by:

entrySet in interface java.util.Map<K,java.lang.Long>

Specified by:

entrySet in interface java.util.SortedMap<K,java.lang.Long>

Returns:

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

See Also:

SortedMap.entrySet()

keySet

public it.unimi.dsi.fastutil.objects.ObjectSortedSet<K> keySet()

Description copied from interface: Object2LongMap

Specified by:

keySet in interface Object2LongMap<K>

Specified by:

keySet in interface Object2LongSortedMap<K>

Specified by:

keySet in interface java.util.Map<K,java.lang.Long>

Specified by:

keySet in interface java.util.SortedMap<K,java.lang.Long>

Overrides:

keySet in class Object2LongMaps.EmptyMap<K>

Returns:

a set view of the keys contained in this map.

Map.keySet()

subMap

public Object2LongSortedMap<K> subMap(K from,
                                      K to)

Description copied from interface: Object2LongSortedMap

Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

Specified by:

subMap in interface Object2LongSortedMap<K>

Specified by:
