C++ Reference: class SmallRevBitSet

Note: This documentation is automatically generated.

This class represents a small reversible bitset (size <= 64). This class is useful to maintain supports.

Method
Cardinality	Return type: int64_t Returns the number of bits set to one.
GetFirstOne	Return type: int64_t Gets the index of the first bit set starting from 0. It returns -1 if the bitset is empty.
IsCardinalityOne	Return type: bool Does it contains only one bit set?
IsCardinalityZero	Return type: bool Is bitset null?
SetToOne	Return type: void Arguments: Solver* const solver, int64_t pos Sets the 'pos' bit.
SetToZero	Return type: void Arguments: Solver* const solver, int64_t pos Erases the 'pos' bit.
SmallRevBitSet	Return type: explicit Arguments: int64_t size
