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:se.sics.caracaldb.utils.TimestampIdFactory.java

private TimestampIdFactory(Address adr) {
    this.address = new byte[6];
    System.arraycopy(adr.getIp().getAddress(), 0, this.address, 0, 4);
    System.arraycopy(Ints.toByteArray(adr.getPort()), 2, this.address, 4, 2);
    byte[] tsB = new byte[bytes];
    Arrays.fill(tsB, (byte) 0);
    System.arraycopy(Longs.toByteArray(System.currentTimeMillis()), 0, tsB, 0, 8);
    this.ts = new FixedInteger(tsB);
    this.counter = com.larskroll.math.mutable.FixedInteger.zero(bytes);
    this.lastId = FixedInteger.zero(bytes);
