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].

isIntrinsicCandidate

public boolean isIntrinsicCandidate(TruffleString.CodeRange codeRange)

Returns true if TruffleString.ByteIndexOfCodePointSetNode may implement the search for this particular code point set in strings with the given code range by dispatching to a compiler intrinsic.
