In this page you can find the example usage for com.google.common.primitives Longs toByteArray.

Prototype

public static byte[] toByteArray(long value) 

Source Link

Document

Returns a big-endian representation of value in an 8-element byte array; equivalent to ByteBuffer.allocate(8).putLong(value).array() .

Usage

From source file:com.temenos.interaction.loader.classloader.CachingParentLastURLClassloaderFactory.java

protected Object calculateCurrentState(FileEvent<File> param) {

    MessageDigest md = DigestUtils.getMd5Digest();
    for (File f : files) {
        md.update(Longs.toByteArray(f.lastModified()));
    }/*from   w w  w .ja v  a2s.  com*/

    Object state = Hex.encodeHexString(md.digest());
    LOGGER.trace(
            "Calculated representation /hash/ of state of collection of URLs for classloader creation to: {}",
            state);
