Gzip

Gzip wraps deflate with a header and a CRC. Select it with Compression.gzip(); Decompressor detects it from its magic number.

Options, each returning a changed copy: level, bufferSize, deflateStrategy, fileName, comment, modificationTime, operatingSystem, fileNameCharset and decompressConcatenated.

Decompressor enforces the default limits; a stream that expands past a ratio of 100 after the first MiB throws LimitExceededException.

Example Usage

Gzip Compression

Compression gzip = Compression.gzip()
        .bufferSize(1024)
        .level(9)
        .comment("comment")
        .deflateStrategy(DeflateStrategy.HUFFMAN_ONLY)
        .operatingSystem(0);
try (Compressor compressor =
        Compressor.builder(Path.of("example.gz"), gzip).build()) {
    compressor.write(Path.of("path/to/file.txt"));
}

Gzip Decompression

try (Decompressor decompressor =
        Decompressor.builder(Path.of("example.gz")).build()) {
    decompressor.write(Path.of("path/to/file.txt"));
}
