Examples with GZIPOutputStream java.util.zip.GZIPOutputStream used on opensource projects

Example 1 with GZIPOutputStream

use of java.util.zip.GZIPOutputStream in project jetty.project by eclipse.

the class GZIPContentDecoderTest method testSmallBlockWithGZIPChunkedAtEnd.

@Test
public void testSmallBlockWithGZIPChunkedAtEnd() throws Exception {
    String data = "0";
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    GZIPOutputStream output = new GZIPOutputStream(baos);
    output.write(data.getBytes(StandardCharsets.UTF_8));
    output.close();
    byte[] bytes = baos.toByteArray();
    // The trailer is 8 bytes, chunk the last 9 bytes
    byte[] bytes1 = new byte[bytes.length - 9];
    System.arraycopy(bytes, 0, bytes1, 0, bytes1.length);
    byte[] bytes2 = new byte[bytes.length - bytes1.length];
    System.arraycopy(bytes, bytes1.length, bytes2, 0, bytes2.length);
    GZIPContentDecoder decoder = new GZIPContentDecoder(pool, 2048);
    ByteBuffer decoded = decoder.decode(ByteBuffer.wrap(bytes1));
    assertEquals(data, StandardCharsets.UTF_8.decode(decoded).toString());
    assertFalse(decoder.isFinished());
    decoder.release(decoded);
    decoded = decoder.decode(ByteBuffer.wrap(bytes2));
    assertEquals(0, decoded.remaining());
    assertTrue(decoder.isFinished());
    decoder.release(decoded);
}

Example 2 with GZIPOutputStream

use of java.util.zip.GZIPOutputStream in project jetty.project by eclipse.

the class GZIPContentDecoderTest method testBigBlock.

@Test
public void testBigBlock() throws Exception {
    String data = "0123456789ABCDEF";
    for (int i = 0; i < 10; ++i) data += data;
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    GZIPOutputStream output = new GZIPOutputStream(baos);
    output.write(data.getBytes(StandardCharsets.UTF_8));
    output.close();
    byte[] bytes = baos.toByteArray();
    String result = "";
    GZIPContentDecoder decoder = new GZIPContentDecoder(pool, 2048);
    ByteBuffer buffer = ByteBuffer.wrap(bytes);
    while (buffer.hasRemaining()) {
        ByteBuffer decoded = decoder.decode(buffer);
        result += StandardCharsets.UTF_8.decode(decoded).toString();
        decoder.release(decoded);
    }
    assertEquals(data, result);
}

    output.close();
    byte[] bytes = baos.toByteArray();
    GZIPContentDecoder decoder = new GZIPContentDecoder(pool, 2048);
    ByteBuffer decoded = decoder.decode(ByteBuffer.wrap(bytes));
    assertEquals(0, decoded.remaining());
}
