Constructor & Destructor Documentation

ProgressBar() [1/3]

osmium::ProgressBar::ProgressBar ( std::size_t max_size, bool enable )

inlinenoexcept

Initializes the progress bar. No output yet.

Parameters

max_size	Max size equivalent to 100%.
enable	Set to false to disable (for instance if stderr is not a TTY).

ProgressBar() [2/3]

osmium::ProgressBar::ProgressBar ( const ProgressBar & )

delete

Member Function Documentation

bar()

display()

void osmium::ProgressBar::display ( )

inlineprivate

done()

void osmium::ProgressBar::done ( )

inline

Call this at the end. Will update the progress bar to 100% and print a final line feed. If this is not called explicitly the destructor will also call this.

file_done()

void osmium::ProgressBar::file_done ( std::size_t file_size )

inline

If you are reading multiple files, call this function after each file is finished.

Parameters

file_size

The size of the file just finished.

operator=() [1/2]

ProgressBar & osmium::ProgressBar::operator= ( const ProgressBar & )

delete

operator=() [2/2]

ProgressBar & osmium::ProgressBar::operator= ( ProgressBar && )

default

remove()

void osmium::ProgressBar::remove ( )

inline

Removes the progress bar. Call this before doing any other output. The next time update() is called, the progress bar will be visible again.

spc()

const char * osmium::ProgressBar::spc ( std::size_t len = full_length )

inlinestaticprivatenoexcept

update()

void osmium::ProgressBar::update ( std::size_t current_size )

inline

Call this function to update the progress bar. Actual update will only happen if the percentage changed from the last time this function was called.

Parameters

current_size

Current size. Used together with the max_size from constructor to calculate the percentage.
