Method Detail

execute

public abstract TruffleString execute(AbstractTruffleString a,
                                      TruffleString.Encoding encoding)

Returns a version of string a that is encoded in the given encoding, which may be the string itself or a converted version. Note that the string itself may be returned even if it was originally created using a different encoding, if the string is byte-equivalent in both encodings.

If no lossless conversion is possible, the string is converted on a best-effort basis; no exception is thrown and characters which cannot be mapped in the target encoding are replaced by '�' (for UTF-*) or '?'.
