Class IOOutputStream

java.io.OutputStream

org.jruby.util.IOOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class IOOutputStream
extends java.io.OutputStream

This class wraps a IRubyObject in an OutputStream. Depending on which messages the IRubyObject answers to, it will have different functionality. The point is that the IRubyObject could exhibit duck typing, in the style of IO versus StringIO, for example. At the moment, the only functionality supported is writing, and the only requirement on the io-object is that it responds to write() and close() like IO.
