Method Detail

execute

public abstract boolean execute(AbstractTruffleString a,
                                int fromIndexA,
                                AbstractTruffleString b,
                                int fromIndexB,
                                int length,
                                TruffleString.Encoding expectedEncoding)

Checks for codepoint equality in a region with the given codepoint index and codepoint length.

Equivalent to:

 for (int i = 0; i < length; i++) {
     if (codePointAt(a, fromIndexA + i) != codePointAt(b, fromIndexB + i)) {
         return false;
     }
 }
 return true;
