arcsdec::v_1_0_0::AudioReaderImpl class
#include <audioreader.hpp>

Abstract base class for AudioReader implementations.

Concrete subclasses of AudioReaderImpl implement AudioReaders for a concrete FileReaderDescriptor.

Base classes

class v_1_0_0::SampleProvider: Inteface for providers of sample sequences.

Constructors, destructors, conversion operators

AudioReaderImpl(): Default constructor.

Public functions

auto acquire_size(const std::string& filename) -> std::unique_ptr<AudioSize>: Provides implementation for acquire_size() of a AudioReader.
auto descriptor() const -> std::unique_ptr<FileReaderDescriptor>: Create a descriptor for this AudioReader implementation.
void process_file(const std::string& filename): Provides implementation for process_file() of some AudioReader.
auto samples_per_read() const -> std::size_t: Return the number of samples to read in one read operation.
void set_samples_per_read(const std::size_t samples_per_read): Set the number of samples to read in one read operation.

Protected functions

void attach_processor_impl(SampleProcessor& processor): Default implementation of attach_processor().
auto use_processor() -> SampleProcessor*: Use the internal SampleProcessor.

Private functions

auto do_acquire_size(const std::string& filename) -> std::unique_ptr<AudioSize> pure virtual: Provides implementation for acquire_size() of an AudioReader.
void do_process_file(const std::string& filename) pure virtual: Provides implementation for process_file() of some AudioReader.
