Return the numeric value of a subset of bits.
- Parameters
-
| value | the original value containing the bitfield. |
| offset | the offset of the least valued bit (e.g. 0 = bitfield starts with bit 0). |
| len | the number of bits to use. |
- Returns
- the value of the bitfield.

inlinestatic |
Set the numeric value of a subset of bits.
- Parameters
-
| value | the original value containing the bitfield. |
| offset | the offset of the least valued bit (e.g. 0 = bitfield starts with bit 0). |
| len | the number of bits to use. |
| newVal | the new value for the bitfield. |
- Returns
- the original value with the bitfield bits overwritten with the new value newVal.
