net.i2p.util.ResettableGZIPInputStream

All Implemented Interfaces:: Closeable, AutoCloseable

Direct Known Subclasses:: ReusableGZIPInputStream

public class ResettableGZIPInputStream
extends InflaterInputStream

GZIP implementation per RFC 1952, reusing java's standard CRC32 and Inflater and InflaterInputStream implementations. The main difference is that this implementation allows its state to be reset to initial values, and hence reused, while the standard GZIPInputStream reads the GZIP header from the stream on instantiation.

Constructor Details
- ResettableGZIPInputStream
  
  public ResettableGZIPInputStream()
  
  Build a new GZIP stream without a bound compressed stream. You need to initialize this with initialize(compressedStream) when you want to decompress a stream.
