Example 6 with CompressionCodec

use of org.apache.pulsar.common.compression.CompressionCodec in project incubator-pulsar by apache.

the class CompressorCodecTest method testCompressDecompress.

    assertEquals(uncompressed.readableBytes(), data.length);
    assertEquals(uncompressed, raw);
    raw.release();

    assertEquals(raw.refCnt(), 0);
    assertEquals(compressed.refCnt(), 0);
    assertEquals(compressed.refCnt(), 0);
