本文整理匯總了TypeScript中ts-promise.Promise類的典型用法代碼示例。如果您正苦於以下問題：TypeScript Promise類的具體用法？TypeScript Promise怎麽用？TypeScript Promise使用的例子？那麽, 這裏精選的類代碼示例或許可以為您提供幫助。
在下文中一共展示了Promise類的7個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1:
(abortError: Error) => {
// Abort pending read, if necessary
if (this._resumer) {
this._resumer(Promise.reject(abortError));
this._resumer = undefined;
}
}示例2:
(enderError: Error) => {
// ender callback failed, but in order to let final stream fail,
// we need to pass 'something' on, and to wait for that to come
// back.
// Finally, make sure to return the enderError.
return Promise.resolve(defaultEnder(error || enderError)).then(
() => Promise.reject(enderError),
() => Promise.reject(enderError)
);
}示例3: filterer
(v: T): void|Promise<void> => {
var b = filterer(v);
if (!b) {
return;
} else if (b === true) { // note: not just `if (b)`!
return writable.write(v);
} else { // more complex return type, probably a Thenable
return Promise.resolve(b).then((resolvedB) => {
if (resolvedB) {
return writable.write(v);
}
});
}
},示例4: return
return (error?: Error) => {
// TODO: an error returned from ender is currently passed on to next
// stream, if stream was not ended with an error yet.
// It'd maybe be better to not have the next stream be ended when an
// error occurred in this ender, but there's no way to send another
// end(), so we have to close it somehow...
return Promise.resolve(error).then(ender).then(
() => defaultEnder(error),
(enderError: Error) => {
// ender callback failed, but in order to let final stream fail,
// we need to pass 'something' on, and to wait for that to come
// back.
// Finally, make sure to return the enderError.
return Promise.resolve(defaultEnder(error || enderError)).then(
() => Promise.reject(enderError),
() => Promise.reject(enderError)
);
}
);
};示例5: Error
.catch(function(){
console.log("error");
return Promise.reject(new Error("Error login"));
})示例6:
export const resolveGlobs = (globs: string[]) : Promise<string[]> => {
return Promise.all(globs.map(pglob)).then(x=> flatten<string>(x));
};示例7: Promise
"use strict";
import { Promise } from "ts-promise";
var prom = new Promise((resolve, reject) => {
setTimeout(() => {
resolve(42);
// or e.g.: reject(new Error("boom"));
}, 100);
});
/// Hello world
Promise.resolve("test").then((v) => {
console.log(v);
});
var p = Promise.resolve();
/*
Promise.setLongTraces(true);
var p = Promise.resolve();
p.then(() => {
//return Promise.reject(new Error("my error"));
}).catch((e) => {
console.error(e.stack);
});
