Member Function Documentation
◆ Cardinality()
| int64 Cardinality | ( | ) | const |
Returns the number of bits set to one.
◆ ClearAll()
| void ClearAll | ( | Solver *const | solver | ) |
Cleans all bits.
◆ GetFirstBit()
| int64 GetFirstBit | ( | int | start | ) | const |
Gets the index of the first bit set starting from start.
It returns -1 if the bitset is empty after start.
◆ IsCardinalityOne()
| bool IsCardinalityOne | ( | ) | const |
Does it contains only one bit set?
◆ IsCardinalityZero()
| bool IsCardinalityZero | ( | ) | const |
Is bitset null?
◆ IsSet()
| bool IsSet | ( | int64 | index | ) | const |
Returns whether the 'index' bit is set.
◆ SetToOne()
| void SetToOne | ( | Solver *const | solver, |
| int64 | index | ||
| ) |
Sets the 'index' bit.
◆ SetToZero()
| void SetToZero | ( | Solver *const | solver, |
| int64 | index | ||
| ) |
Erases the 'index' bit.
