Method Detail

comparator
public java.util.Comparator<? super K> comparator()
Description copied from interface:Reference2LongSortedMap
Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.- Specified by:
comparator
in interfaceReference2LongSortedMap<K>
- Specified by:
comparator
in interfacejava.util.SortedMap<K,java.lang.Long>
- See Also:
SortedMap.comparator()
-
reference2LongEntrySet
public ObjectSortedSet<Reference2LongMap.Entry<K>> reference2LongEntrySet()
Description copied from interface:Reference2LongMap
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 anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
reference2LongEntrySet
in interfaceReference2LongMap<K>
- Specified by:
reference2LongEntrySet
in interfaceReference2LongSortedMap<K>
- Overrides:
reference2LongEntrySet
in classReference2LongMaps.EmptyMap<K>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public 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:
