- template<size_tPrimary,size_tResidual=0,size_tExtent=Dynamic,LVQPackingStrategyStrategy=Sequential,typenameAlloc=lib::Allocator<std::byte>>
classLVQDataset Public Functions
- size_tprimary_dataset_alignment()const
Return the alignment of the primary dataset.
- const_value_typeget_datum(size_ti)const
Access both levels of the two-level dataset.
Return a type that lazily combines the primary and residual.
- voidprefetch(size_ti)const
Prefetch data in the first and second level datasets.
- const_primary_value_typeget_primary(size_ti)const
Access only the first level of the dataset.
- const_residual_value_typeget_residual(size_ti)const
Access only the residual dataset.
- constprimary_type&get_primary_dataset()const
Access the entire primary dataset.
- voidprefetch_primary(size_ti)const
Prefetch only the primary dataset.
- size_tprimary_dataset_alignment()const
Utilities and Helpers
- structReload
Dispatch type indicating that a compressed dataset should be reloaded directly.
LVQ based loaders can either perform dataset compression online, or reload a previously saved dataset.
Using this type in LVQ loader constructors indicates that reloading is desired.
Public Functions
- inlineexplicitReload(conststd::filesystem::path&directory)
Construct a new Reloader.
- Parameters:
directory – The directory where a LVQ compressed dataset was previously saved.
- inlineexplicitReload(conststd::filesystem::path&directory)
