Method Detail

comparator

public java.util.Comparator<? super K> comparator()
Description copied from interface: Object2CharSortedMap
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 Object2CharSortedMap<K>
Specified by:
comparator in interface java.util.SortedMap<K,java.lang.Character>
See Also:
SortedMap.comparator()

object2CharEntrySet

public ObjectSortedSet<Object2CharMap.Entry<K>> object2CharEntrySet()
Description copied from interface: Object2CharMap
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 Object2CharMap.entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:
object2CharEntrySet in interface Object2CharMap<K>
Specified by:
object2CharEntrySet in interface Object2CharSortedMap<K>
Overrides:
object2CharEntrySet in class Object2CharMaps.EmptyMap<K>
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Object2CharMap.entrySet()

entrySet

public ObjectSortedSet<java.util.Map.Entry<K,java.lang.Character>> entrySet()
Description copied from interface: Object2CharMap
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 Object2CharMap<K>
Specified by:
entrySet in interface Object2CharSortedMap<K>
Specified by:
entrySet in interface java.util.Map<K,java.lang.Character>
Specified by:
entrySet in interface java.util.SortedMap<K,java.lang.Character>
Overrides:
entrySet in class Object2CharMaps.EmptyMap<K>
Returns:
a set view of the mappings contained in this map.
See Also:
Map.entrySet()

keySet

public ObjectSortedSet<K> keySet()
Description copied from interface: Object2CharMap
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 Object2CharMap<K>
Specified by:
keySet in interface Object2CharSortedMap<K>
Specified by:
keySet in interface java.util.Map<K,java.lang.Character>
Specified by:
keySet in interface java.util.SortedMap<K,java.lang.Character>
Overrides:
keySet in class Object2CharMaps.EmptyMap<K>
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

subMap

public Object2CharSortedMap<K> subMap(K from,
                                      K to)
Description copied from interface: Object2CharSortedMap
Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

Note that this specification strengthens the one given in SortedMap.subMap(Object,Object).

Specified by:
subMap in interface Object2CharSortedMap<K>
Specified by:
subMap in interface java.util.SortedMap<K,java.lang.Character>
See Also:
SortedMap.subMap(Object,Object)

headMap

public Object2CharSortedMap<K> headMap(K to)
Description copied from interface: Object2CharSortedMap
Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

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

Specified by:
headMap in interface Object2CharSortedMap<K>
Specified by:
headMap in interface java.util.SortedMap<K,java.lang.Character>
See Also:
SortedMap.headMap(Object)

tailMap

public Object2CharSortedMap<K> tailMap(K from)
Description copied from interface: Object2CharSortedMap
Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.

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

Specified by:
tailMap in interface Object2CharSortedMap<K>
Specified by:
tailMap in interface java.util.SortedMap<K,java.lang.Character>
See Also:
SortedMap.tailMap(Object)

firstKey

public K firstKey()
Specified by:
firstKey in interface java.util.SortedMap<K,java.lang.Character>

lastKey

public K lastKey()
Specified by:
lastKey in interface java.util.SortedMap<K,java.lang.Character>
