uk.co.terminological.rjava.RSystemOut

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class RSystemOut
extends PrintStream

Delegates the print stream output from System.out to a per-thread set of ByteArrayPrintStreams keyed on thread id. This intercepts any write to System.out and first of all picks a concurrent map of print streams keyed by thread Id. This is possibly quite a lot slower than the default. This is like it is so that later on the RFuture class can asynchronously find out what console output has been gathered so far for a given thread without being in that thread. This lets system.out be called by a long running method in a thread and the output be available in the RFuture monitor thread.
