Method Detail

comparator

public CharComparator comparator()
Description copied from interface: Char2DoubleSortedMap
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 Char2DoubleSortedMap
Specified by:
comparator in interface java.util.SortedMap<java.lang.Character,java.lang.Double>
See Also:
SortedMap.comparator()

char2DoubleEntrySet

public ObjectSortedSet<Char2DoubleMap.Entry> char2DoubleEntrySet()
Description copied from interface: Char2DoubleMap
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 Char2DoubleMap.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:
char2DoubleEntrySet in interface Char2DoubleMap
Specified by:
char2DoubleEntrySet in interface Char2DoubleSortedMap
Overrides:
char2DoubleEntrySet in class Char2DoubleMaps.EmptyMap
Returns:
a type-specific set view of the mappings contained in this map.
See Also:
Char2DoubleMap.entrySet()

entrySet

public ObjectSortedSet<java.util.Map.Entry<java.lang.Character,java.lang.Double>> entrySet()
Description copied from interface: Char2DoubleMap
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 Char2DoubleMap
Specified by:
entrySet in interface Char2DoubleSortedMap
Specified by:
entrySet in interface java.util.Map<java.lang.Character,java.lang.Double>
Specified by:
entrySet in interface java.util.SortedMap<java.lang.Character,java.lang.Double>
Overrides:
entrySet in class Char2DoubleMaps.EmptyMap
Returns:
a set view of the mappings contained in this map.
See Also:
Map.entrySet()

keySet

public CharSortedSet keySet()
Description copied from interface: Char2DoubleMap
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 Char2DoubleMap
Specified by:
keySet in interface Char2DoubleSortedMap
Specified by:
keySet in interface java.util.Map<java.lang.Character,java.lang.Double>
Specified by:
keySet in interface java.util.SortedMap<java.lang.Character,java.lang.Double>
Overrides:
keySet in class Char2DoubleMaps.EmptyMap
Returns:
a set view of the keys contained in this map.
See Also:
Map.keySet()

subMap

public Char2DoubleSortedMap subMap(char from,
                                   char to)
Description copied from interface: Char2DoubleSortedMap
Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

Specified by:
subMap in interface Char2DoubleSortedMap
See Also:
SortedMap.subMap(Object,Object)

headMap

public Char2DoubleSortedMap headMap(char to)
Description copied from interface: Char2DoubleSortedMap
Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

SortedMap.headMap(Object)

tailMap

public Char2DoubleSortedMap tailMap(char from)

Specified by:
firstCharKey in interface Char2DoubleSortedMap

SortedMap.lastKey()

headMap

public Char2DoubleSortedMap headMap(java.lang.Character oto)
Description copied from interface: Char2DoubleSortedMap
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 Char2DoubleSortedMap
