Function Documentation

CopyHeightIndexToHashIndex()

static bool CopyHeightIndexToHashIndex ( CDBIterator &  db_it, CDBBatch &  batch, const std::string &  index_name, int  start_height, int  stop_height  )

static

DestroyAllBlockFilterIndexes()

void DestroyAllBlockFilterIndexes

(

)

Destroy all open block filter indexes.

DestroyBlockFilterIndex()

bool DestroyBlockFilterIndex

(

BlockFilterType

filter_type

)

Destroy the block filter index with the given type. Returns false if no such index exists. This just releases the allocated memory and closes the database connection, it does not delete the index data.

ForEachBlockFilterIndex()

void ForEachBlockFilterIndex

(

std::function< void(BlockFilterIndex &)>

fn

)

Iterate over all running block filter indexes, invoking fn on each.

GetBlockFilterIndex()

BlockFilterIndex* GetBlockFilterIndex

(

BlockFilterType

filter_type

)

Get a block filter index by type. Returns nullptr if index has not been initialized or was already destroyed.

InitBlockFilterIndex()

bool InitBlockFilterIndex	(	BlockFilterType	filter_type,
		size_t	n_cache_size,
		bool	f_memory = false,
		bool	f_wipe = false
	)

Initialize a block filter index for the given type if one does not already exist. Returns true if a new index is created and false if one has already been initialized.

LookupOne()

static bool LookupOne ( const CDBWrapper &  db, const CBlockIndex *  block_index, DBVal &  result  )

static

LookupRange()

static bool LookupRange ( CDBWrapper &  db, const std::string &  index_name, int  start_height, const CBlockIndex *  stop_index, std::vector< DBVal > &  results  )
