| * Construct a new empty BytesBuilder. |
| * |
| * If copy is true, the data is always copied when added to the list. If it copy |
| * is false, the data is only copied if needed. That means that if the lists are |
| * changed after added to the BytesBuilder, it may effect the output. Default is |
| * true. |
| * @description Checks that this constructor creates a new empty BytesBuilder. |
