Sorted Map
A subtype of map that provides iteration over keys conforming to the natural sorting order, backed by a tree map.
map<KeyType, ValueType>
Subtypes | Supertypes | Comparable types |
|---|---|---|
none | map<KeyType, ValueType> | java.util.SortedMap<KeyType, ValueType> |
new treemap
Parameter type | Result type |
|---|---|
(KeyType => ValueType)... | map<KeyType, ValueType> |
Creates an empty tree map. Optionally, initial values may be specified right in the new map creation expression.
sorted_map<string, int> map = new treemap<string, int> {"A" => 1, "B" => 2, "C" => 3};
Operand type | Parameter type | Result type |
|---|---|---|
sorted_map<KeyType, ValueType> | KeyType | sorted_map<KeyType, ValueType> |
Results in a sorted_map that is a submap of the original map, containing all the mappings in the original sorting order, starting with the first key and up to but not including the specified key.
map.headMap (upTo);
Operand type | Parameter type | Result type |
|---|---|---|
sorted_map<KeyType, ValueType> | KeyType | sorted_map<KeyType, ValueType> |
Results in a sorted_map that is a submap of the original map, containing all the mappings in the original sorting order, starting with the specified key.
map.tailMap (from);
Operand type | Parameter type | Result type |
|---|---|---|
sorted_map<KeyType, ValueType> | KeyType, KeyType | sorted_map<KeyType, ValueType> |
Results in a sorted_map that is a submap of the original map, containing all the mappings in the original sorting order, starting with the first specified key and up to but not including the second specified key.
map.tailMap (from,upTo);
