Method Detail

execute

public abstract int execute(AbstractTruffleString a,
                            TruffleString.Encoding expectedEncoding)

Return the number of codepoints in the string.

If the string is not encoded correctly (if its coderange is TruffleString.CodeRange.BROKEN), every broken minimum-length sequence in the encoding (4 bytes for UTF-32, 2 bytes for UTF-16, 1 byte for other encodings) adds 1 to the length.
