Class FilteredOutputStream

java.lang.Object
  java.io.OutputStream
      com.mucommander.io.FilteredOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

Direct Known Subclasses:

LocalFile.LocalOutputStream

public class FilteredOutputStream
extends java.io.OutputStream

This class provides a proper implementation of an OutputStream filter.

Unlike java.io.FilterOutputStream, this method delegates all methods to an underlying OutputStream and nothing more. In particular, write(byte[]) and write(byte[], int, int) do not call write(int) repeatedly (very unefficient) but delegate to the corresponding OutputStream methods. This makes this class much safer to use from a performance perspective than java.io.FilteredOutputStream.
