              net.i2p.util.ResettableGZIPOutputStream

All Implemented Interfaces:

Closeable, Flushable

Direct Known Subclasses:

ReusableGZIPOutputStream

public class ResettableGZIPOutputStream
extends DeflaterOutputStream

GZIP implementation per RFC 1952, reusing java's standard CRC32 and Deflater implementations. The main difference is that this implementation allows its state to be reset to initial values, and hence reused, while the standard GZIPOutputStream writes the GZIP header to the stream on instantiation, rather than on first write.
