DEPRECATED

Don't use this library!

It relied on accessing internals of java.util.zip.Inflater, which have changed in JDK 11.

Instead, use GzipCompressorInputStream from Apache compress-commons. An example of how to use it is at https://github.com/cldellow/warc-service/blob/e95f8f5906c39efeb781a47b343a7cec179af7e3/src/main/scala/com/cldellow/warc/framework/WarcHandler.scala#L62

gzip

Emit offsets of nested GZIP streams.

GZIP has the interesting property that a sequence of concatenated GZIP streams can be read as though it were a single GZIP stream.

The Web Archive (WARC) format takes advantage of this to store tens of thousands of GZIP streams in a single file. When processing such a file, it can be useful to know the start of the underlying stream. The stock java.util.zip.GZIPInputStream class does not expose this.

This library patches that class expose a callback which gets invoked with the offsets of the member streams.

Usage

int[] offsets = new int[100];

GZIPInputStream gzis = new GZIPInputStream(is, (member, offset) -> { offsets[member] = offset; });
