Document

Writes all the remaining bytes of the src byte buffer to this buffer's current position, and increases both buffers' position by the number of bytes copied.

Usage

From source file:com.offbynull.portmapper.pcp.FilterPcpOption.java

private static ByteBuffer toDataSection(int prefixLength, int remotePeerPort, InetAddress remotePeerIpAddress) {
    Validate.inclusiveBetween(0, 128, prefixLength); // 0 indicates 'no filter'
    Validate.inclusiveBetween(0, 65535, remotePeerPort); // 0 indicates 'all ports'
    Validate.notNull(remotePeerIpAddress);

    ByteBuffer buffer = ByteBuffer.allocate(20);
    buffer.put((byte) 0); // reserved
    buffer.put((byte) prefixLength);
    buffer.putShort((short) remotePeerPort);
    buffer.put(NetworkUtils.convertToIpv6Array(remotePeerIpAddress));

    return buffer;
