实现Promise的cn.dinodev.spring.commons.promise中的类

修饰符和类型	类	说明
class	AbstractPromise<D>
class	DeferredObject<D>	An implementation of Deferred interface.

返回Promise的cn.dinodev.spring.commons.promise中的方法

修饰符和类型	方法	说明
Promise<D>	AbstractPromise.always(AlwaysCallback<? super D> callback)
Promise<D>	Promise.always(AlwaysCallback<? super D> callback)	This method will register AlwaysCallback so that when a Deferred object is either resolved (Deferred.resolve(Object)) or rejected (Deferred#reject(Object)), AlwaysCallback will be triggered.
Promise<D>	AbstractPromise.done(Consumer<? super D> callback)
Promise<D>	Promise.done(Consumer<? super D> callback)	This method will register DoneCallback so that when a Deferred object is resolved (Deferred.resolve(Object)), DoneCallback will be triggered.
Promise<D>	AbstractPromise.fail(Consumer<Throwable> callback)
Promise<D>	Promise.fail(Consumer<Throwable> callback)	This method will register FailCallback so that when a Deferred object is rejected (Deferred#reject(Object)), FailCallback will be triggered.
Promise<D>	Deferred.promise()	Return an Promise instance (i.e., an observer).
Promise<D>	DeferredObject.promise()
Promise<D>	AbstractPromise.then(Consumer<? super D> callback)
Promise<D>	AbstractPromise.then(Consumer<? super D> doneCallback, Consumer<Throwable> failCallback)
Promise<D>	Promise.then(Consumer<? super D> doneCallback)	Equivalent to done(DoneCallback)
Promise<D>	Promise.then(Consumer<? super D> doneCallback, Consumer<Throwable> failCallback)	Equivalent to done(DoneCallback).fail(FailCallback)

cn.dinodev.spring.commons.utils中Promise的使用

返回Promise的cn.dinodev.spring.commons.utils中的方法

修饰符和类型	方法	说明
static <R> Promise<R>	TaskUtils.exec(Callable<R> task, Predicate<R> checker, int attempts, Class<? extends RuntimeException>... throwOutExceptions)	无参数，有返回的任务调用
static <R> Promise<R>	TaskUtils.exec(Callable<R> task, Predicate<R> checker, int attempts, Duration nap, Class<? extends RuntimeException>... throwOutExceptions)	无参数，有返回的任务调用
<T, U, R> Promise<R>	TaskUtils.exec(BiFunction<T,U,R> task, T paramFirst, U paramSecond, Predicate<R> checker, int attempts, Class<? extends RuntimeException>... throwOutExceptions)	task接受两个参数，并返回执行结果
<T, U, R> Promise<R>	TaskUtils.exec(BiFunction<T,U,R> task, T paramFirst, U paramSecond, Predicate<R> checker, int attempts, Duration nap, Class<? extends RuntimeException>... throwOutExceptions)	task接受两个参数，并返回执行结果
<T, R> Promise<R>	TaskUtils.exec(Function<T,R> task, T param, Predicate<R> checker, int attempts, Class<? extends RuntimeException>... throwOutExceptions)	task接受一个参数，并返回执行结果
<T, R> Promise<R>	TaskUtils.exec(Function<T,R> task, T param, Predicate<R> checker, int attempts, Duration nap, Class<? extends RuntimeException>... throwOutExceptions)	task接受一个参数，并返回执行结果
