    • reserve

      public void reserve(int tagId, int length)
      Specifies tagId and size of the tag value. All tags should be reserved in order like in generated message. Use MessageStructure.VARIABLE_LENGTH to define the tag value that could be increased dynamically for concrete parameter. Keep in mind, this will slow performance and spawn new Objects in runtime. Reserved field will be added to the end of the structure.
      Parameters:
      tagId - tagId
      length - required amount of bytes for value or MessageStructure.VARIABLE_LENGTH.

    • reserve

      public void reserve(int position, int tagId, int length)
      Specifies tagId and size of the tag value. Reserved field will be inserted at specified position.
      Parameters:
      position - position to insent the tag
      tagId - tagId
      length - required amount of bytes for value or MessageStructure.VARIABLE_LENGTH.
