Constructor & Destructor Documentation

DeviceOutputStream() [1/2]

template<StreamElement Element>

xentara::utils::io::DeviceOutputStream< Element >::DeviceOutputStream ( )

defaultnoexcept

This constructor does not set a device. you must assign a valid object before using the class.

DeviceOutputStream() [2/2]

template<StreamElement Element>

xentara::utils::io::DeviceOutputStream< Element >::DeviceOutputStream ( std::reference_wrapper< OutputDevice >  device )

noexcept

Constructor that sets the device.

Parameters

device
