public class PrintWriter_flushing
extends PrintWriter

Print writer which flushes the unerlying output stream after each print. Convenient for debugging purpose, due to inconsistent java lib flushing strategy.

Since the java io architecture has grown historically, the PrintWriter.flush() strategy is not always "fast enough" for debugging purposes. Therefore this class patches the PrintWriter.print(String) and PrintWriter.println(String) methods to call flush() immediately and "hard" as soon as their output is delivered.

Attention, beside these both methods no other output functions have been patched/overridden!
