public class BitmapLabelSet
extends LabelSetField

2.2.3. Bitmap Label Set In the case of Action = 4, the bitmap the label set format is given by: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | 4 | Num Labels | Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Base Label | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Bit Map Word #1 (Lowest numerical labels) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ : : +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Bit Map Word #N (Highest numerical labels) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Where Num Labels in this case tells us the number of labels represented by the bit map. Each bit in the bit map represents a particular label with a value of 1/0 indicating whether the label is in the set or not. Bit position zero represents the lowest label and corresponds to the base label, while each succeeding bit position represents the next label logically above the previous. The size of the bit map is Num Label bits, but the bit map is padded out to a full multiple of 32 bits so that the TLV is a multiple of four bytes. Bits that do not represent labels (i.e., those in positions (Num Labels) and beyond SHOULD be set to zero and MUST be ignored.
