Example 70 with GZIPOutputStream

use of java.util.zip.GZIPOutputStream in project robovm by robovm.

the class DeflaterOutputStreamTest method createInflaterStream.

/**
     * Creates an optionally-flushing deflater stream, writes some bytes to it,
     * and flushes it. Returns an inflater stream that reads this deflater's
     * output.
     *
     * <p>These bytes are written on a separate thread so that when the inflater
     * stream is read, that read will fail when no bytes are available. Failing
     * takes 3 seconds, co-ordinated by PipedInputStream's 'broken pipe'
     * timeout. The 3 second delay is unfortunate but seems to be the easiest
     * way demonstrate that data is unavailable. Ie. other techniques will cause
     * the dry read to block indefinitely.
