Class MonitoredOutputStream

java.lang.Object

java.io.OutputStream

java.io.ByteArrayOutputStream

org.springframework.roo.process.manager.internal.MonitoredOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class MonitoredOutputStream
extends ByteArrayOutputStream

Ensures the NotifiableFileMonitorService.notifyChanged(String) method is invoked when close() is called.

This is useful for ensuring the file monitoring system is notified of all changed files, even those which are changed very rapidly on disk and would not normally be detected using the file system's "last updated" timestamps.

1.0
