void DestroyAllBlockFilterIndexes | ( | ) |
Destroy all open block filter indexes.
Definition at line 480 of file blockfilterindex.cpp.
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.
Definition at line 475 of file blockfilterindex.cpp.
void ForEachBlockFilterIndex | ( | std::function< void(BlockFilterIndex &)> | fn | ) |
Iterate over all running block filter indexes, invoking fn on each.
Definition at line 460 of file blockfilterindex.cpp.
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 454 of file blockfilterindex.cpp.
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.

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.
