Here is the call graph for this function:

Here is the caller graph for this function:

DestroyAllBlockFilterIndexes()

void DestroyAllBlockFilterIndexes

(

)

Destroy all open block filter indexes.

Definition at line 511 of file blockfilterindex.cpp.

Here is the caller graph for this function:

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.

Here is the caller graph for this function:

ForEachBlockFilterIndex()

void ForEachBlockFilterIndex

(

std::function< void(BlockFilterIndex &)>

fn

)

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

Here is the caller graph for this function:

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.

Definition at line 485 of file blockfilterindex.cpp.

Here is the caller graph for this function:

InitBlockFilterIndex()

bool InitBlockFilterIndex	(	std::function< std::unique_ptr< interfaces::Chain >()>	make_chain,
		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.

CF_HEADERS_CACHE_MAX_SZ

constexpr size_t CF_HEADERS_CACHE_MAX_SZ {2000}

constexpr

Maximum size of the cfheaders cache We have a limit to prevent a bug in filling this cache potentially turning into an OOM.

At 2000 entries, this cache is big enough for a 2,000,000 length block chain, which we should be enough until ~2047.
