Detailed Description

template<typename ChunkValue_, typename Index_>
class tatami_chunked::CustomDenseChunkedMatrixManager< ChunkValue_, Index_ >

Manager of chunks for a CustomDenseChunkedMatrix.

Template Parameters

ChunkValue_	Numeric type of the data values in each chunk.
Index_	Integer type for the row/column indices of the CustomDenseChunkedMatrix.

Member Function Documentation

new_workspace()

template<typename ChunkValue_ , typename Index_ >

virtual std::unique_ptr< CustomDenseChunkedMatrixWorkspace< ChunkValue_, Index_ > > tatami_chunked::CustomDenseChunkedMatrixManager< ChunkValue_, Index_ >::new_workspace ( ) const

pure virtual

Returns

A CustomDenseChunkedMatrixWorkspace instance to unpack each chunk of interest.

new_workspace_exact()

template<typename ChunkValue_ , typename Index_ >

std::unique_ptr< CustomDenseChunkedMatrixWorkspace< ChunkValue_, Index_ > > tatami_chunked::CustomDenseChunkedMatrixManager< ChunkValue_, Index_ >::new_workspace_exact ( ) const

inline

Returns

A CustomDenseChunkedMatrixWorkspace instance (or any of its subclasses) to unpack each chunk of interest.

This is a non-virtual counterpart to new_workspace() that may optionally be shadowed by a method with the same signature in each subclass. If implemented in a subclass, this should return a pointer to its specific CustomDenseChunkedMatrixWorkspace subclass, rather than to the base class. This provides some devirtualization opportunities within CustomDenseChunkMatrix when Manager_ is hard-coded to a specific CustomDenseChunkedMatrixManager subclass.

prefer_rows()

template<typename ChunkValue_ , typename Index_ >

virtual bool tatami_chunked::CustomDenseChunkedMatrixManager< ChunkValue_, Index_ >::prefer_rows ( ) const

pure virtual

Returns

Whether extraction of rows is the preferred access pattern.

row_stats()

template<typename ChunkValue_ , typename Index_ >

virtual const ChunkDimensionStats< Index_ > & tatami_chunked::CustomDenseChunkedMatrixManager< ChunkValue_, Index_ >::row_stats ( ) const

pure virtual

Returns

Statistics for the rows, i.e., the number of rows in the matrix, the number of rows in each chunk, the number of chunks along all rows.

In all calls to CustomDenseChunkedMatrixManager::extract(), each chunk_row_id will be less than the ChunkDimensionsStats::num_chunks of the return value.

column_stats()

template<typename ChunkValue_ , typename Index_ >

virtual const ChunkDimensionStats< Index_ > & tatami_chunked::CustomDenseChunkedMatrixManager< ChunkValue_, Index_ >::column_stats ( ) const

pure virtual

Returns

Statistics for the columns, i.e., the number of columns in the matrix, the number of columns in each chunk, the number of chunks along all columns.

In all calls to CustomDenseChunkedMatrixManager::extract(), each chunk_column_id will be less than the ChunkDimensionsStats::num_chunks of the return value.
