Detailed Description

template<typename Value_, typename Index_>
class tatami::MyopicDenseExtractor< Value_, Index_ >

Extract an element of the target dimension in dense form without an oracle.

Template Parameters

Value_	Data value type, should be numeric.
Index_	Row/column index type, should be integer.

Member Function Documentation

fetch()

template<typename Value_ , typename Index_ >

virtual const Value_ * tatami::MyopicDenseExtractor< Value_, Index_ >::fetch ( Index_ i, Value_ * buffer )

pure virtual

buffer may not necessarily be filled upon extraction if a pointer can be returned to the underlying data store. This can be checked by comparing the returned pointer to buffer; if they are the same, buffer has been filled.

Parameters

	i	Index of the target dimension element, i.e., the row or column index.
[out]	buffer	Pointer to an array of length no less than N, where N is defined as: the number of columns, when extracting each row. the number of rows, when extracting each column. the block length, when extracting a contiguous block from each row/column. the number of indices, when extracting an indexed subset of each row/column.

Returns

Pointer to an array containing the values from the i-th dimension element. This is guaranteed to hold N values.
