Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Teams. Re: inputstream to outputstream Re: inputstream to outputstream

I managed the following: val data = Array[Byte](31, 0x80.toByte, 0, 3, 100, 101)

In this tutorial, we will learn how to use Scala's Immutable Stream to perform common operations such as initialize an infinite Stream, use the cons operator, take elements from a Stream and create an empty Stream.. And, don't forget to review the Data Structures tutorial before delving into Scala's Immutable and Mutable collections. Re: inputstream to outputstream

Hi Scala list, What is the idiomatic way to create a Stream from an InputStream? What I have in the question, is a way to obtain the char array.Won't that create a huge linked list, then convert it to an array?

I don't like this answer, sometimes you really need a FileInputStream because you need methods from its API like getChannel() for example, and he didn't asked if it is a good idea or not to use an InputStream, just if it is possible or not to create a file input stream from an input stream.

*/ def processFully(buffer: Appendable): InputStream => Unit = processFully(appendLine(buffer)) /** Returns a function `InputStream => Unit` that will call the passed * function with all data read. Because Stream elements are computed lazily, a Stream can be long... infinitely long. package io.alphard.sbt.util import java.io.

Given that you're only going to read in the file once, then Iterator is a much better choice: def inputStreamToByteArray(is: InputStream): Array[Byte] = Iterator continually is.read takeWhile (-1 !=) map (_.toByte) toArray

Java.util.Properties.load() Method - The java.util.Properties.load(InputStream inStream) method reads a property list (key and element pairs) from the input byte stream. I'd caution against using Stream, if holding a reference to the head element then streams can easily consume a lot of memory.

This is a classic example of the word count map-reduce program. It increases performance of our program.

Streams have the same performance characteristics as In the above output, we can see that second element is not evaluated. InputStreamReader(InputStream in_strm, String charsetName) : Creates an InputStreamReader that uses the named charset; Methods: ready() : java.io.InputStreamReader.ready() tells whether the Character stream is ready to be read or not. acknowledge that you have read and understood our Going back to 2.8, it's more likeHow about buffered version of solution based on streams plus ByteArraOutputStream to minimize boilerplate around final array growing?pass the stream to ByteStreams.toByteArray method for conversionThanks for contributing an answer to Stack Overflow! Here is a simple Scala class that demonstrates this idea: Top.

A Scala Stream is like a List, except that its elements are computed lazily, in a manner similar to how a view creates a lazy version of a collection. Scala supports lazy computation. In above syntax the head of this stream is 1, and the tail of it has 2 and 3. By using our site, you Are they even a part of the standard library?No. Data input streams and data output streams represent Unicode strings in a format that is a slight modification of UTF-8. DataInputStream is not necessarily safe for multithreaded access.

This method implements the general contract of the corresponding read method of the InputStream class. Embed this gist in your website. Read a file using Stream (Scala). Streams are specified to lazy computation.When we wanted to take 10 numbers from a Stream, although it only contained 3 elements, it did not throw any IndexOutOfBoundsException.In above example by using map function we are transforming the input collection to a new output collection.If you like GeeksforGeeks and would like to contribute, you can also write an article using Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below.
