Class Transcoder

java.lang.Object

org.jruby.util.encoding.Transcoder

Direct Known Subclasses:

CharsetTranscoder

public abstract class Transcoder
extends java.lang.Object

Abstract superclass for all transcoders. This and its implementations are roughly equivalent to rb_econv_t in MRI.

Constructor Detail

Transcoder

public Transcoder(ThreadContext context,
                  org.jcodings.Encoding outEncoding,
                  org.jcodings.Encoding inEncoding)

Method Detail

open

public static Transcoder open(ThreadContext context,
                              byte[] sourceEncoding,
                              byte[] destinationEncoding,
                              int ecflags,
                              IRubyObject replacement)

open0

public static Transcoder open0(ThreadContext context,
                               byte[] sourceEncoding,
                               byte[] destinationEncoding,
                               int ecflags,
                               IRubyObject replacement)

strConvEncOpts

public static org.jruby.util.ByteList strConvEncOpts(ThreadContext context,
                                                     org.jruby.util.ByteList value,
                                                     org.jcodings.Encoding fromEncoding,
                                                     org.jcodings.Encoding toEncoding,
                                                     int ecflags,
                                                     IRubyObject ecopts)

This will try and transcode the supplied ByteList to the supplied toEncoding. It will use forceEncoding as its encoding if it is supplied; otherwise it will use the encoding it has tucked away in the bytelist. This will return a new copy of a ByteList in the request encoding or die trying (ConverterNotFound). c: rb_str_conv_enc_opts
