Examples with NullInputStream org.apache.commons.io.input.NullInputStream used on opensource projects

Example 1 with NullInputStream

use of org.apache.commons.io.input.NullInputStream in project jackrabbit-oak by apache.

the class StatsCollectingStreamsTest method downloadCallback.

@Test
public void downloadCallback() throws Exception {
    NullInputStream in = new NullInputStream(1042);
    TestCollector stats = new TestCollector();
    InputStream wrappedStream = StatsCollectingStreams.wrap(stats, "foo", in);
    assertEquals(0, stats.callbackCount);
    //Copy the content to get size
    CountingOutputStream cos = new CountingOutputStream(new NullOutputStream());
    IOUtils.copy(wrappedStream, cos);
    assertEquals(1042, cos.getCount());
    //Stream not closed so no callback
    assertEquals(0, stats.callbackCount);
    wrappedStream.close();
    assertEquals(1042, stats.size);
    assertEquals(1, stats.downloadCompletedCount);
}

private static void writeFile(Directory directory, String fileName, long size) throws Exception {
    IndexOutput o = directory.createOutput(fileName, IOContext.DEFAULT);
    o.copyBytes(new InputStreamDataInput(new NullInputStream(size)), size);
    o.close();
}
