Class GunzipOutputStream

java.lang.Object

java.io.FilterOutputStream

java.util.zip.InflaterOutputStream

net.i2p.i2ptunnel.util.GunzipOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class GunzipOutputStream
extends InflaterOutputStream

Gunzip implementation per RFC 1952, reusing java's standard CRC32 and Inflater and InflaterOutputStream implementations. Note that the underlying InflaterOutputStream cannot be reused after close(), so we don't have a Reusable version of this. Sets up GunzipOutputStream -- InflaterOutputStream -- CRC32OutputStream -- uncompressedStream Not a public API, subject to change, not for external use. Modified from net.i2p.util.ResettableGZIPInputStream to use Java 6 InflaterOutputstream
