Class JConsole.BlockingPipedInputStream  

java.lang.Object
  java.io.InputStream
      java.io.PipedInputStream
          edu.emory.mathcs.util.swing.JConsole.BlockingPipedInputStream

All Implemented Interfaces:

java.io.Closeable

Enclosing class:

JConsole

---

public static class JConsole.BlockingPipedInputStream

extends java.io.PipedInputStream

The overridden read method in this class will not throw "Broken pipe" IOExceptions; It will simply wait for new writers and data. This is used by the JConsole internal read thread to allow writers in different (and in particular ephemeral) threads to write to the pipe. It also checks a little more frequently than the original read(). Warning: read() will not even error on a read to an explicitly closed pipe (override closed to for that).
