Options for data extraction from an UnknownMatrix.

Member Data Documentation

maximum_cache_size

size_t tatami_r::UnknownMatrixOptions::maximum_cache_size = -1

Size of the cache, in bytes. If -1, this is determined from DelayedArray::getAutoBlockSize().

require_minimum_cache

bool tatami_r::UnknownMatrixOptions::require_minimum_cache = true

Whether to automatically enforce a minimum size for the cache, regardless of maximum_cache_size. This minimum is chosen to ensure that all chunks overlapping one row (or a slice/subset thereof) can be retained in memory, so that the same chunks are not repeatedly re-read from disk when iterating over consecutive rows/columns of the matrix.
