Description
Default
callback
function

Examples
Run a function asynchronously and get the result
future = runAsync( () => {
return "Hello World!";
} );
writeOutput( future.get() );
Result: Hello World!
Run a function after the asynchronous function and use a five milliseconds timeout when calling get()
future = runAsync( () => {
return 5;
} ).then( ( Any input ) => {
return input + 2;
} );
result = future.get( 3 ); // 3 is timeout(in ms)
writeOutput( result );
Result: 5
Run a function asynchronously with then() and error()
future = runAsync( () => {
return 5;
} ).then( ( Any input ) => {
return input + 2;
} ).error( () => {
return "Error occurred.";
} );
writeOutput( future.get() );
Result: 7
Additional Examples
future = runAsync( () => {
return 10;
} ).then( ( Any input ) => {
return input + 20;
} );
dump( future );
result = future.get( 10 ); // 10 is timeout(in ms)
writeOutput( result );
// output is 30
