Method Summary

Modifier and Type	Method and Description
static Promise	all(net.sourceforge.htmlunit.corejs.javascript.Context context, net.sourceforge.htmlunit.corejs.javascript.Scriptable thisObj, Object[] args, net.sourceforge.htmlunit.corejs.javascript.Function function) Returns a Promise that resolves when all of the promises in the iterable argument have resolved, or rejects with the reason of the first passed promise that rejects.
Promise	catch_js(Object onRejected) Returns a Promise and deals with rejected cases only.
String	getLogDetails()
static Promise	race(net.sourceforge.htmlunit.corejs.javascript.Context context, net.sourceforge.htmlunit.corejs.javascript.Scriptable thisObj, Object[] args, net.sourceforge.htmlunit.corejs.javascript.Function function) Returns a Promise that that resolves or rejects as soon as one of the promises in the iterable resolves or rejects, with the value or reason from that promise.
static Promise	reject(net.sourceforge.htmlunit.corejs.javascript.Context context, net.sourceforge.htmlunit.corejs.javascript.Scriptable thisObj, Object[] args, net.sourceforge.htmlunit.corejs.javascript.Function function) Returns a Promise object that is rejected with the given value.
static Promise	resolve(net.sourceforge.htmlunit.corejs.javascript.Context context, net.sourceforge.htmlunit.corejs.javascript.Scriptable thisObj, Object[] args, net.sourceforge.htmlunit.corejs.javascript.Function function) Returns a Promise object that is resolved with the given value.
Promise	then(Object onFulfilled, Object onRejected) It takes two arguments, both are callback functions for the success and failure cases of the Promise.
