More Output

One of the core IO classes is called Output

Normally the Output API will be encountered when a Resource object is created. But a resource is not required to have an Output object.

Basic Output

All Output resources extend the Output trait so the following operations can be used on any Output resource (ReadableByteChannel or OutputStream for example).

This example does not try to cover all operations since they are covered in multiple examples like in the basic-read-write examples.

    import scalax.io._

    val output:Output = Resource.fromFileString("someFile")

    output.writeIntsAsBytes(1,2,3)
    output.write("hello")(Codec.UTF8)
    output.writeStrings(List("hello","world")," ")(Codec.UTF8)

Convert Object To Output

In addition to Resource.fromFoo methods to create Resources (which are often Output objects) There is a second option for converting certain objects directly to an Output object. This example shows how to convert a File to an output object

    import scalax.io._
    import java.io.File
    import Output.asOutputConverter

    // By default files can be converted to an Output Object by importing
    // Output.asOutputConverter and calling asOutput on the file
    val output:Output = new File("aFile").asOutput

    // needed for the write call below
    implicit val codec = Codec.UTF8

    output.write("data is being written to file")
