Detailed Description

template<typename OutputValue_, typename InputValue_, typename Index_, class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>
class tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >

Delayed isometric operation on a single matrix.

Implements any operation that preserves the shape of the matrix and operates on each matrix value independently. This operation is "delayed" in that it is only evaluated during data extraction, e.g., with MyopicDenseExtractor::fetch() or friends. We only consider "unary" operations that involve a single Matrix - see DelayedBinaryIsometricOperation for operations between two Matrix instances.

This class is inspired by the DelayedUnaryIsoOp classes from the DelayedArray Bioconductor package.

Template Parameters

OutputValue_	Type of the result of the operation.
InputValue_	Type of the value of the input matrix.
Index_	Integer type for the row/column indices.
Operation_	Helper class representing the operation of interest.

Member Function Documentation

◆ nrow()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

Index_ tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::nrow ( ) const

inlinevirtual

Returns: Number of rows.

Implements tatami::Matrix< OutputValue_, Index_ >.

◆ ncol()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

Index_ tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::ncol ( ) const

inlinevirtual

Returns: Number of columns.

Implements tatami::Matrix< OutputValue_, Index_ >.

◆ is_sparse()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

bool tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::is_sparse ( ) const

inlinevirtual

Returns: Boolean indicating whether this matrix is sparse.

This can be used to choose between dense and sparse outputs.

Implements tatami::Matrix< OutputValue_, Index_ >.

◆ is_sparse_proportion()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

double tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::is_sparse_proportion ( ) const

inlinevirtual

Returns: Approximate proportion of the matrix that is sparse.

This is defined as the proportion of matrix elements that lie within sparse submatrices. It is intended for use in Matrix representations that consist of combinations of multiple submatrices (e.g., DelayedBind), allowing them to derive a suitable value for is_sparse() based on whether most of its submatrices are sparse. (A more granular approach would be to report the density of structural non-zero elements, but this may not be known by all representations at construction time.)

Implements tatami::Matrix< OutputValue_, Index_ >.

◆ prefer_rows()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

bool tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::prefer_rows ( ) const

inlinevirtual

Returns: The preferred dimension for extracting values. If true, row-wise extraction is preferred; if false, column-wise extraction is preferred.

Implements tatami::Matrix< OutputValue_, Index_ >.

◆ prefer_rows_proportion()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

double tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::prefer_rows_proportion ( ) const

inlinevirtual

Returns: Approximate proportion of the matrix that prefers row-level access.

This is defined as the proportion of matrix elements that lie within submatrices that prefer row-level access. It is useful for determining the return value of prefer_rows() in combined matrices consisting of both row- and column-preferred submatrices. In such cases, the net preference can be determined based on the combined size of the submatrices for each preference. (A more granular approach would be to report the iteration cost on each dimension, but this is difficult to estimate.)

Implements tatami::Matrix< OutputValue_, Index_ >.

◆ uses_oracle()

template<typename OutputValue_ , typename InputValue_ , typename Index_ , class Operation_ = DelayedUnaryIsometricOperationHelper<OutputValue_, InputValue_, Index_>>

bool tatami::DelayedUnaryIsometricOperation< OutputValue_, InputValue_, Index_, Operation_ >::uses_oracle ( bool row ) const

inlinevirtual

Parameters

row	Row access if `true`, column access otherwise.

Returns: Whether this matrix's tatami::Extractor classes make use of oracle predictions for row (if row = true) or column access (otherwise).

The output of this method indicates whether callers should construct an oracle for use in ExtractorBase::set_oracle(). If false, callers should not bother to pass an oracle as it will be ignored.

Create an oracle-aware extractor that retrieves an indexed subset of the non-target dimension in sparse form.

Parameters

row	Whether to create a row-wise extractor, i.e., the rows are the target dimension.
oracle	An oracle supplying predictions of the next requested row (if `row = true`) or column (otherwise).
indices_ptr	Pointer to a vector of sorted and unique column indices (if `row = true`) or row indices (otherwise). This should not be NULL.
opt	Options for extraction.

Returns: Object for extracting an indexed subset from each row (if row = true) or column (otherwise) in sparse form. This should not outlive the parent Matrix from which it was created.
