Method Detail

execute

public final TruffleStringIterator execute(AbstractTruffleString a,
                                           TruffleString.Encoding expectedEncoding)

Returns a TruffleStringIterator, which allows iterating this string's code points, with best-effort error handling.

Since:

22.1

execute

public abstract TruffleStringIterator execute(AbstractTruffleString a,
                                              TruffleString.Encoding expectedEncoding,
                                              TruffleString.ErrorHandling errorHandling)

Returns a TruffleStringIterator, which allows iterating this string's code points. The iterator is initialized to begin iteration at the end of the string, use TruffleStringIterator.PreviousNode to iterate in reverse order.

Parameters:

errorHandling - analogous to TruffleString.CodePointAtIndexNode.
