      @Deprecated public TLVMsg(int tag, byte[] value) throws IllegalArgumentException
      Deprecated.
      In most cases, a message is created to attach it to the list.
      It can be done by: 
        TLVList tl = ...;
  tl.append(tag, value);
      If for some reason this is not possible then a message can be created: 
        TLVList tl = TLVListBuilder.createInstance().build(); // or just new TLVList();
  tl.append(tag, value);
  TLVMsg tm = tl.find(tag);
      The intention is to not promote the use of TLVMsg outside. Due to the lack of compatibility of various TLV types at TLVList.append(TLVMsg)
      Constructs a TLV message from tag and value.
      Parameters:
      tag - id
      value - tag value
      Throws:
      IllegalArgumentException

    • TLVMsg

      protected TLVMsg(int tag, byte[] value, int tagSize, int lengthSize) throws IllegalArgumentException
      Constructs a TLV message using explicit tag and length sizes.
      Parameters:
      tag - the TLV tag identifier
      value - the TLV value bytes
      tagSize - fixed tag size, or 0 for auto-detection
      lengthSize - fixed length size, or 0 for auto-detection
      Throws:
      IllegalArgumentException - if the supplied tag or value is invalid
