A user would rarely wrap resources inside of a ManagedResource themselves. The following examples show how to use java.util.zip.GZIPInputStream.These examples are extracted from open source projects. Re: Scala Automatic Resource Management Incubator Project For production code I would also suggest to make sure that the source is closed again. They're actually mostly the same, it's just a matter of how you write the sample.  There's no particular reason I chose my version besides that's how I wrote it.   The library actually would support your syntax (just with ManagedResource instead of managed). import scala.io.Source import scala.util.Try def niceFeedbackReadResource(resource: String): List[String] = Try(Source.fromResource(resource).getLines.toList) .recover(throw new FileNotFoundException(resource)) To get meaningful FNFEs instead. {FileOutputStream, InputStream, OutputStream} import java.io. Applications that are defining subclass of InputStream must provide method, returning the next byte of input.

Hi, i'm Andrew , an Software Engineer in Test who loves to learn something new in coding and making machines do the routine work instead of me. For a user to get access to a Managed object, they'd have to use it inside a for-comprehension. In this case, the Handle is an InputStream and the Resource is a FileChannel. It represents input stream of bytes. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. This is an excerpt from the Scala Cookbook (partially modified for the internet). Eventually, i found a nice and working way to load resources in scala : Source.fromInputStream(getClass().getClassLoader().getResourceAsStream("filename") That give's an InputStream which you can process then however you want. InputStreamReader(InputStream in_strm, Charset cs) : creates an InputStreamReader that uses the given charset. An example of where you would want a translated resource was FileChannels. However, if you need an opposite direction you are stuck, because there is no appropriate API in Scala … How to Convert scala.io.Source to InputStream Usually you convert Java's InputStream to Scala's Source and this kind of conversion is not a problem for an average Scala developer.
InputStreamReader(InputStream in_strm) : Creates an InputStreamReader that uses the default charset.

I'm located in Amsterdam at the moment.My initial goal for my fabricator library that i'm working on is that it can be used in both Java and Scala projects. It was rather intended to be a library-writer's library.

You can vote up the examples you like and your votes will be used in our system to produce more good examples. Instead, user-facing libraries (like IO, Transactions, Locks, and anything else that needs to open a resource and ensure that it is closed after it's been used) would provide access to objects that were Managed. representing an input stream of bytes. Answer2: The InputStream (Handle) needs to be opened and closed safely, but the user doesn't ever need to know that the InputStream even exists, the user only ever deals with the FileChannel. The problem i faced recently was that , when i packaged scala code into jar file and tried to use it in another java project, i got "file not found" exception in a step when my library was trying to read data from resources file. Re: Scala Automatic Resource Management Incubator Project This page is no longer maintained — There's one thing I took an issue to: private val inputStream = new FileInputStream(file.javaFile) private val lineIterator = new BufferedLineIterator(inputStream); def lines(): Iterator[String] = lineIterator Based on my understanding of the original Scalax ManagedResource stuff, ManagedResource was not really meant to be a user-facing library. I don't understand what that initial val input = ManagedResource(connection.getInputStream).where managed() gives us an appropriately pimped wrapper around theJosh, could you explain the relative merits of these two?Copyright © 2012 École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland

Re: Scala Automatic Resource Management Incubator Project InputStreamReader(InputStream in_strm, CharsetDecoder dec) : Creates an InputStreamReader that uses the given charset decoder. Here, libraryDependencies is a set of dependencies, and by using +=, we’re adding the scala-parser-combinators dependency to the set of dependencies that sbt will go and fetch when it starts up. InputStream class is the superclass of all the io classes i.e. Looks ok. A Traversable is a more interesting way to do this, since you can then auto-close the resource. Now, in any Scala file, you can import classes, objects, etc, from scala-parser-combinators with a regular import. /* sxr -- Scala X-Ray * Copyright 2009 Mark Harrah */ package sxr import java.io. My project structure was simple :At first, i was trying to read my resource file by giving relative path , but unfortunately this doesn't work when it comes to packaging your code.
