Method Details

comparator

public CharComparator comparator()

Description copied from interface: Char2ReferenceSortedMap

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

Specified by:

comparator in interface Char2ReferenceSortedMap<V>

Specified by:

comparator in interface SortedMap<Character,V>

See Also:

• SortedMap.comparator()

char2ReferenceEntrySet

public ObjectSortedSet<Char2ReferenceMap.Entry<V>> char2ReferenceEntrySet()

Description copied from interface: Char2ReferenceMap

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:

char2ReferenceEntrySet in interface Char2ReferenceMap<V>

Specified by:

char2ReferenceEntrySet in interface Char2ReferenceSortedMap<V>

Overrides:

char2ReferenceEntrySet in class Char2ReferenceMaps.EmptyMap<V>

Returns:

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

See Also:

• Map.entrySet()

entrySet

@Deprecated
public ObjectSortedSet<Map.Entry<Character,V>> 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 Char2ReferenceMap<V>

Specified by:

entrySet in interface Char2ReferenceSortedMap<V>

Specified by:

entrySet in interface Map<Character,V>

Specified by:

entrySet in interface SortedMap<Character,V>

Returns:

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

See Also:

• SortedMap.entrySet()

keySet

public CharSortedSet keySet()

Description copied from interface: Char2ReferenceMap

Specified by:

keySet in interface Char2ReferenceMap<V>

Specified by:

keySet in interface Char2ReferenceSortedMap<V>

Specified by:

keySet in interface Map<Character,V>

Specified by:

keySet in interface SortedMap<Character,V>

Overrides:

keySet in class Char2ReferenceMaps.EmptyMap<V>

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

subMap

public Char2ReferenceSortedMap<V> subMap(char from,
 char to)

Description copied from interface: Char2ReferenceSortedMap

headMap

public Char2ReferenceSortedMap<V> headMap(char to)

Description copied from interface: Char2ReferenceSortedMap

See Also:

• SortedMap.headMap(Object)

tailMap

public Char2ReferenceSortedMap<V> tailMap(char from)

Description copied from interface: Char2ReferenceSortedMap

Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.
