Interface ThreadIO

All Known Implementing Classes:

ThreadIOImpl

public interface ThreadIO

Enable multiplexing of the standard IO streams for input, output, and error.

This service guards the central resource of IO streams. The standard streams are singletons. This service replaces the singletons with special versions that can find a unique stream for each thread. If no stream is associated with a thread, it will use the standard input/output that was originally set.
