public final class MultiProgress

Object
MultiProgress

Several progress bars drawn together, one line each, for work that runs in parallel:

try (MultiProgress all = new MultiProgress()) {
    ProgressBar a = all.add("images", 120);
    ProgressBar b = all.add("videos", 8);
    // ... a.step() and b.step() from any thread ...
    all.println("skipped broken.png");
}

On a terminal the bars are redrawn ten times a second by a background thread, so a bar that is not stepped still shows its rate and an unknown total still animates; stepping only updates numbers and is cheap from any thread. Off a terminal each bar prints a line as it passes every tenth of its total (at most one a second) and a final line when it completes.

Constructors

public MultiProgress() A group on standard output.

Methods

`public` `ProgressBar add(String label, long total)`	Adds a bar for `total` units of work; a total of 0 or less is unknown and the bar animates without a percentage.
`public void println(String text)`	Prints `text` above the bars.
`public boolean isLive()`	Whether the bars redraw in place.
`public void close()`	Stops redrawing and leaves the final state of every bar on screen; bars still running are shown as they are.
