Class Range

constructor

• new Range(lower: Comparable, upper: Comparable): Range

  Create a new range from 2 values.

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • lower: Comparable

    The lower bound of this range
  • upper: Comparable

    The upper bound of this range

  Returns Range

  Throws

  If lower is greater than upper

  Example

  const range = new Range(100, 200);
  Copy

lower

upper

[iterator]

• "[iterator]"(): IterableIterator<Comparable>

  An iterable that contains this.lower and this.upper.

  Time complexity: O(1)

  Space complexity: O(1)

  Returns IterableIterator<Comparable>

  Example

  const [lower, upper] = range;
  Copy

equals

• equals(range: Range): boolean

  Check whether a given range has the same lower and upper bounds as this one.

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • range: Range

    Range to compare

  Returns boolean

  Whether the other range has the same lower and upper bounds as this one

  Example

  const a = new Range(0, 100);
  const b = new Range(0, 100);
  
  a.equals(a); // true
  a.equals(b); // true
  Copy

  Example

  const a = new Range(0, 100);
  const b = new Range(150, 150);
  
  a.equals(b); // true
  Copy

has

• has(value: Comparable): boolean

  Returns true if value is within this.lower and this.upper, false otherwise. The >= and <= operators are used to compare value.

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • value: Comparable

  Returns boolean

  Example

  const range = new Range(100, 200);
  
  console.log(range.has(150)); // true
  console.log(range.has(300)); // false
  Copy

intersects

• intersects(range: Range): boolean

  Check if this range and a given range have any intersection.

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • range: Range

    Range to compare

  Returns boolean

  Whether the ranges intersect

  Example

  const a = new Range(100, 200);
  const b = new Range(150, 250);
  
  a.intersects(b); // true
  Copy

  Example

  const a = new Range(100, 200);
  const b = new Range(300, 400);
  
  a.intersects(b); // false
  Copy

isSubrange

• isSubrange(range: Range): boolean

  Check whether this range contains the given range

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • range: Range

    Range to compare

  Returns boolean

  Whether this range contains the given range

  Example

  const a = new Range(0, 100);
  const b = new Range(25, 75);
  
  a.isSubRange(b); // true
  b.isSubRange(a); // false
  Copy

isSuperrange

• isSuperrange(range: Range): boolean

  Check whether a given range contains this range.

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • range: Range

    Range to compare

  Returns boolean

  Whether this range is contained within the other one

  Example

  const a = new Range(0, 100);
  const b = new Range(25, 75);
  
  a.isSuperrange(b); // false
  b.isSuperrange(a); // true
  Copy

Staticfrom

• from(iterable: Iterable<Comparable>): Range

  Create a new range from the first 2 values of an iterable.

  Time complexity: O(1)

  Space complexity: O(1)

  Parameters

  • iterable: Iterable<Comparable>

    The iterable to create a range from

  Returns Range

  A new range

  Example

  const range = Range.from([100, 200]);
  Copy
