Function enableRedirect

Enable stdout/stderr redirection.

Pass methods for the stdout and stderr output to be redirected to. These methods must accept an error as the first argument, although this will probably never be set and can be ignored. The second argument is the data that was redirected.

Setting any method to null or undefined will disable the redirect for that method. This also allows you not set any handler which does not make any sense at all.

Examples

Redirect all data to the js console

import { stdout } from 'java-bridge';

const guard = stdout.enableRedirect((_, data) => {
    console.log('Stdout:', data);
}, (_, data) => {
    console.error('Stderr:', data);
});
Copy

Redirect stdout to the js console

const guard = stdout.enableRedirect((_, data) => {
    console.log('Stdout:', data);
});
Copy

Redirect stderr to the js console

const guard = stdout.enableRedirect(null, (_, data) => {
   console.error('Stderr:', data);
});
Copy

Redirect nothing to the js console (y tho)

This enables you to print nothing to nowhere.

// Why would you do this?
const guard = stdout.enableRedirect(null, null);

// Or
const guard = stdout.enableRedirect();
Copy
