Method Detail

execute

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

Compare strings a and b byte-by-byte. Returns zero if a and b are equal. If a is equal to b up to its length, but b is longer than a, a negative value is returned. In the inverse case, a positive value is returned. Otherwise, elements a[i] and b[i] at a byte index i are different. If a[i] is greater than b[i], a positive value is returned, otherwise a negative value is returned.
