Detailed Description

template<bool oracle_, typename Value_, typename Index_>
class tatami::FullSparsifiedWrapper< oracle_, Value_, Index_ >

Wrap a full dense extractor in the sparse interface.

This can be used to quickly implement the full sparse extraction methods for a dense Matrix subclass. The dense extraction is performed as usual and every value is treated as a structural non-zero; this wrapper just adds the associated indices to satisfy the sparse extraction interface.

Template Parameters

oracle_	Whether an oracle is involved.
Value_	Type of the matrix values.
Index_	Type of the row/column indices.

Parameters

dense	Instance of a dense extractor that retrieves the full extent of the non-target dimension. If `oracle_ = true`, this should be an instance of a `MyopicDenseExtractor` subclass; otherwise it should be an `OracularDenseExtractor` instance.
extent	Extent of the row/column extracted by `d`.
opt	Options for extraction.
