Method Detail

execute

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

Get the string's "byte-based" TruffleString.CodeRange. This differs from TruffleString.GetCodeRangeNode in the following way:

• A string is only considered to be in the TruffleString.CodeRange.ASCII code range if its encoding is byte-based, so TruffleString.Encoding.UTF_16 and TruffleString.Encoding.UTF_32 cannot be TruffleString.CodeRange.ASCII.
• TruffleString.CodeRange.LATIN_1 and TruffleString.CodeRange.BMP are mapped to TruffleString.CodeRange.VALID
.

The return value is always one of TruffleString.CodeRange.ASCII, TruffleString.CodeRange.VALID or TruffleString.CodeRange.BROKEN.
