Method Details
- fromRanges
  
  public static TruffleString.CodePointSet fromRanges(int[] ranges, TruffleString.Encoding encoding)
  
  Creates a new TruffleString.CodePointSet from the given list of ranges. This operation is expensive, it is recommended to cache the result.
  
  Parameters:
  
  ranges - a sorted list of non-adjacent codepoint ranges. For every two consecutive array elements, the first is interpreted as the range's inclusive lower bound, and the second element is the range's inclusive upper bound. Example: an array [1, 4, 8, 10] represents the inclusive ranges [1-4] and [8-10].
