Class GZIPOutputStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

java.util.zip.DeflaterOutputStream

com.caucho.quercus.lib.zlib.GZIPOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class GZIPOutputStream
extends java.util.zip.DeflaterOutputStream

As opposed to java's GZIPOutputStream, this class allows for more control on what is written to the underlying OutputStream.
