Detailed Description

template<typename Value_>
class tatami_chunked::DenseSlabFactory< Value_ >

Factory for dense slabs.

An instance of this class allocates a single memory pool during its construction. Each slab is simply a pointer into this pool at regular offsets. The idea is to allocate one large block for caching in, e.g., LruSlabCache, improving performance by avoiding repeated requests to the allocator. This also reduces fragmentation that could increase memory usage beyond the expected cache size.

Template Parameters

Value_

Type of the data in each slab.

Constructor & Destructor Documentation

DenseSlabFactory() [1/2]

template<typename Value_ >

template<typename Index_ >

tatami_chunked::DenseSlabFactory< Value_ >::DenseSlabFactory ( std::size_t slab_size, Index_ max_slabs )

inline

Template Parameters

Index_

Integer type of the maximum number of slabs, see the template parameter of the same name in SlabCacheStats.

Parameters

slab_size	Size of the slab, in terms of data elements.
max_slabs	Maximum number of slabs.

DenseSlabFactory() [2/2]

template<typename Value_ >

template<typename Index_ >

tatami_chunked::DenseSlabFactory< Value_ >::DenseSlabFactory ( const SlabCacheStats< Index_ > & stats )

inline

Template Parameters

Index_

Integer type of the dimension extent.

Parameters

stats

Slab cache statistics.

Member Function Documentation

create()

template<typename Value_ >

Slab tatami_chunked::DenseSlabFactory< Value_ >::create ( )

inline

Create a new slab, i.e., designate a portion of the memory pool for use through the returned pointer. This should not be called more than max_slabs times.

Returns

Slab containing a pointer to the memory pool.
