Class ChangedFileOutputStream

java.lang.Object

java.io.OutputStream

org.eclipse.m2e.core.internal.builder.plexusbuildapi.ChangedFileOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class ChangedFileOutputStream
extends OutputStream

Writes to the file only if content of the file is different. TODO. Current implementation defers actual writing to the output file until invocation of close() method. This results in missed/ignored IOExceptions in some cases. First, OutputStream.flush() method does not actually flush buffer to the disk. Second, any problems writing to the file will be reported as IOException thrown by close(), which are generally ignored.
