Class ThreadLocalInputStream

java.lang.Object

java.io.InputStream

com.martiansoftware.nailgun.ThreadLocalInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

class ThreadLocalInputStream
extends InputStream

The class name is pretty descriptive. This creates an InputStream much like a FilterInputStream, but with the wrapped InputStream being local to the current Thread. By setting System.in to a ThreadLocalInputStream, different Threads can read from different InputStreams simply by using System.in. Of course, the init() method must be called by the Thread that wishes to use the wrapped stream.
