Public Member Functions
virtual	~AbstractThresholdConditionChecker ()=default
BIP9Stats	GetStateStatisticsFor (const CBlockIndex *pindex, std::vector< bool > *signalling_blocks=nullptr) const
	Returns the numerical statistics of an in-progress BIP9 softfork in the period including pindex If provided, signalling_blocks is set to true/false based on whether each block in the period signalled.
ThresholdState	GetStateFor (const CBlockIndex *pindexPrev, ThresholdConditionCache &cache) const
	Returns the state for pindex A based on parent pindexPrev B.
int	GetStateSinceHeightFor (const CBlockIndex *pindexPrev, ThresholdConditionCache &cache) const
	Returns the height since when the ThresholdState has started for pindex A based on parent pindexPrev B, all blocks of a period share the same.
