Class CharMap<T>

The number of entires in this map.

This is different from size. In general, you should use size, because it has the same semantics as Set#size and Map#size.

This is equivalent to [...this.entries()].length.

Returns whether this map is empty.

This is equivalent to this.size === 0 and this.entryCount === 0.

The number of characters in this map. This is different from entryCount.

This is equivalent to [...this.keys()].reduce((count, range) => count + range.max - range.min + 1, 0).

Deletes all entries in the map.

Returns a new map with all values mapped by the given function.

If no function is given, the identity function is used.

Deletes all characters in the given range.

This is equivalent to [...range].forEach(char => this.delete(char)).

Returns all key-value pairs in the map.

Entries will be returned in the order of ascending ranges.

Invokes the given callback for every item of the character map.

This method is implemented more efficiently than other iterator based methods, so chose forEach where every possible.

Returns the value associated with the given character of undefined if the character is not key in the map.

Returns whether the given character is a key in the map.

Returns whether every character in the given range is a key in the map.

This is equivalent to: [...chars].every(char => this.has(char)).

Returns whether some character in the given range is a key in the map.

This is equivalent to: [...chars].some(char => this.has(char)).

Returns a mapping from the values of this map to its keys.

Returns all ranges of characters that are keys in the map.

Keys will be returned in the same order as this.entries().

Sets the value for all characters in the given character set.

This is equivalent to [...charSet.characters()].forEach(char => this.set(char, value)).

Sets the value for all characters in the given range.

This is equivalent to [...chars].forEach(char => this.set(char, value)).

Returns all values in the map. Values might not be unique if more than one range maps to the same value.

Values will be returned in the same order as this.entries().
