Detailed Description

template<typename algorithm_executor_type>
class seqan3::algorithm_result_generator_range< algorithm_executor_type >

An input range over the algorithm results generated by the underlying algorithm executor.

Template Parameters
algorithm_executor_typeThe type of the underlying algorithm executor; must be of type seqan3::detail::algorithm_executor_blocking.

Provides a lazy input-range interface over the algorithm results generated by the underlying algorithm executor. The algorithms are computed in a lazy fashion, such that when incrementing the next algorithm result is fetched from the executor. The algorithm result will be cached such that dereferencing the associated iterator is constant.

◆ algorithm_result_generator_range()

template<typename algorithm_executor_type >
seqan3::algorithm_result_generator_range< algorithm_executor_type >::algorithm_result_generator_range ( algorithm_executor_type &&  algorithm_executor)

Parameters
[in]algorithm_executorThe buffer to take ownership from.

Constructs a new algorithm range by taking ownership over the passed algorithm buffer.

Member Function Documentation

◆ begin()

template<typename algorithm_executor_type >
constexpr algorithm_range_iterator seqan3::algorithm_result_generator_range< algorithm_executor_type >::begin ( )
inlineconstexpr

Returns an iterator to the first element of the algorithm range.

Returns
An iterator to the first element.

Invocation of this function will trigger the computation of the first algorithm.

◆ end()

template<typename algorithm_executor_type >
constexpr std::default_sentinel_t seqan3::algorithm_result_generator_range< algorithm_executor_type >::end ( )
inlineconstexprnoexcept

Returns a sentinel signaling the end of the algorithm range.

Returns
a sentinel.

The algorithm range is an input range and the end is reached when the internal buffer over the algorithm results has signaled end-of-stream.

◆ next()

template<typename algorithm_executor_type >
bool seqan3::algorithm_result_generator_range< algorithm_executor_type >::next ( )
inlineprotected

Receives the next algorithm result from the executor buffer.

Returns
true if a new algorithm result could be fetched, otherwise false.

Fetches the next element from the underlying algorithm executor if available.
