Class IOChannel

java.lang.Object

org.jruby.util.IOChannel

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, java.nio.channels.Channel

Direct Known Subclasses:

IOChannel.IOReadableByteChannel, IOChannel.IOReadableWritableByteChannel, IOChannel.IOWritableByteChannel

public abstract class IOChannel
extends java.lang.Object
implements java.nio.channels.Channel

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.
