Can someone please point me to an example of decompressing a zlib file idiomatically

Yeah I see a lot of java example but I would like to look at idiomatic kotlin code

[karelpeeters]

It's exactly the same.

Oh alright. Thanks 🙂. Expected it to be much cleaner. Like iterating over iis instead of for loop

[karelpeeters]

Ah you're asking about reading an inputstream to a string? I think there's something neater for that indeed, let me check.

Take a compressed ByteArray and generate decompressed String/ByteArray

[karelpeeters]

Sorry for not getting back to you sooner, there's InputStream.transferTo for this. The whole thing looks like this now:

val source = ByteArray(100)

val inStream = ByteArrayInputStream(source)
val defStream = InflaterInputStream(inStream)

val outStream = ByteArrayOutputStream()
defStream.transferTo(outStream)

val array = outStream.toByteArray()
val string = String(array, Charsets.UTF_8)

[tekjar]

Awesome. No need to close these streams?

[karelpeeters]

Wel behind the scenes that's what transferTo does, but sure you don't need to do it yourself.

Nice. Thanks alot 🙂
