Here is the call graph for this function:

Here is the caller graph for this function:

int CBlockTreeDB::ReadHeightIndex	(	int	low,
		int	high,
		int	minconf,
		std::vector< std::vector< uint256 >> &	blocksOfHashes,
		std::set< dev::h160 > const &	addresses
	)

Iterates through blocks by height, starting from low.

Parameters

low	start iterating from this block height
high	end iterating at this block height (ignored if <= 0)
minconf	stop iterating of the block height does not have enough confirmations (ignored if <= 0)
blocksOfHashes	transaction hashes in blocks iterated are collected into this vector.
addresses	filter out a block unless it matches one of the addresses in this set.

Returns

the height of the latest block iterated. 0 if no block is iterated.
