Some protocols But there are also some substantial differences between the Like files, network protocolsĬan be text, binary, or a mix of both. We useīufferedSink to encode output and BufferedSource to decode input. Sending and receiving data over the network is a bit like writing and reading files. Note that Okio doesn’t yet support sockets on Kotlin/Native or Kotlin/JS. Use Float.floatToIntBits() and Double.doubleToLongBits() to encode floating point values.Ĭommunicate on a Socket ( Java/ Kotlin) ¶.Use Utf8.size() to compute the number of bytes of an encoded string.Write tests with golden values! Confirming that your program emits the expected result can make.To begin on a 4-byte boundary so it is necessary to add zeros to maintain the alignment.Įncoding other binary formats is usually quite similar. The trickiest part of this program is the format’s required padding.
Kotlin codepoints code#
Use BufferedSource.readUtf8CodePoint() to read a single variable-length code point, andīufferedSink.writeUtf8CodePoint() to write ( IOException :: class ) private fun serialize ( o : Any? ): ByteString This is handy in length-prefixed encodings like protocol buffers. Use Utf8.size() to count the number of bytes required to encode a string as UTF-8 without actuallyĮncoding it. Them, there are convenient APIs for dealing with low-level UTF-8 strings. Is problematic because String.length() returns a surprising result: the number of UTF-16 chars andįor the most part Okio lets you ignore these problems and focus on your data. In particular, most emoji use two Java chars. It is a bad encoding because it uses a 16-bitĬhar for most characters, but some don’t fit. Use an obsolete character encoding called UTF-16. Though we use UTF-8 whenever we read or write strings in I/O, when they are in memory Java Strings Glyph is a single code point that’s called NFC when it’s multiple it’s NFD. When a glyph has an accent or another adornment it may be represented as a single complexĬode point ( é) or as a simple code point ( e) followed by its modifiers ( ´). When encoding strings you need to be mindful of the different ways that strings are represented andĮncoded. Most programs should use the UTF-8 methods only. Otherwise you may accidentally create data that Methods require that you specify a character set. If you need another character set, readString() and writeString() are there for you. It reduces time spent writing and maintaining the same code for different platforms while retaining the flexibility and benefits of native programming. World has standardized on UTF-8 everywhere, with some rare uses of other charsets in legacy systems. Support for multiplatform programming is one of Kotlin’s key benefits. Support multiple character sets was awful and we didn’t even have emoji! Today we’re lucky that the Incompatible character encodings: ISO-8859-1, ShiftJIS, ASCII, EBCDIC, etc. In the above APIs you can see that Okio really likes UTF-8. getValue () + "\n" ) // Slower!
