Examples of GzipCompressorInputStream

org.apache.commons.compress.compressors.gzip.GzipCompressorInputStream
Input stream that decompresses .gz files. This supports decompressing concatenated .gz files which is important when decompressing standalone .gz files.
{@link java.util.zip.GZIPInputStream} doesn't decompress concatenated .gzfiles: it stops after the first member and silently ignores the rest. It doesn't leave the read position to point to the beginning of the next member, which makes it difficult workaround the lack of concatenation support.
Instead of using GZIPInputStream, this class has its own .gz container format decoder. The actual decompression is done with {@link java.util.zip.Inflater}.
