Method Detail

combineAllOf

public static <T> PromisedValues<T> combineAllOf(java.util.List<java.util.concurrent.CompletionStage<T>> cfs)

combinePromisedValues

public static <T> PromisedValues<T> combinePromisedValues(java.util.List<PromisedValues<T>> promisedValues)

thenAccept

public PromisedValues<T> thenAccept(java.util.function.Consumer<PromisedValues<T>> handler)

Description copied from interface: PromisedValues

When the all the futures complete, this call back will be invoked with this PromisedValues as a parameter

Specified by:

thenAccept in interface PromisedValues<T>

Parameters:

handler - the call back which will be given this object

Returns:

a new PromisedValues which you can compose more computations with

succeeded

public boolean succeeded()

Specified by:

succeeded in interface PromisedValues<T>

Returns:

true if all the futures completed successfully

failed

public boolean failed()

Specified by:

failed in interface PromisedValues<T>

Returns:

true if any of the the futures completed unsuccessfully

isDone

public boolean isDone()

Description copied from interface: PromisedValues

The true if the all the futures have completed (and hence this PromisedValues has completed)

Specified by:

isDone in interface PromisedValues<T>

Returns:

true if all the futures have completed

cause

public java.lang.Throwable cause()

Description copied from interface: PromisedValues

The exception cause or null if it didn't fail

Specified by:

cause in interface PromisedValues<T>

Returns:

an exception or null if the future did not fail

succeeded

public boolean succeeded(int index)

Description copied from interface: PromisedValues

The true if the CompletionStage at the specified index succeeded

Specified by:

succeeded in interface PromisedValues<T>

Parameters:

index - the index of the CompletionStage

Returns:

true if the future at the specified index succeeded

cause

public java.lang.Throwable cause(int index)

Description copied from interface: PromisedValues

The exception cause at the specified index or null if it didn't fail

Specified by:

cause in interface PromisedValues<T>

Parameters:

index - the index of the CompletionStage

Returns:

an exception or null if the future did not fail

get

public T get(int index)

Description copied from interface: PromisedValues

The value at index or null if it failed

Specified by:

get in interface PromisedValues<T>

Parameters:

index - the index of the future

Returns:

the value of the future

toList

public java.util.List<T> toList()

Description copied from interface: PromisedValues

Returns the underlying values as a list

Specified by:

toList in interface PromisedValues<T>

Returns:

the list of underlying values

size

public int size()

Specified by:

size in interface PromisedValues<T>

Returns:

the number of CompletionStages under the covers

join

public java.util.List<T> join()

Description copied from interface: PromisedValues

Waits for the underlying futures to complete. To better conform with the use of common functional forms, if a computation involved in the completion of this CompletableFuture threw an exception, this method throws an (unchecked) CompletionException with the underlying exception as its cause.

Specified by:

join in interface PromisedValues<T>

Returns:

the list of completed values similar to PromisedValues.toList()

toCompletableFuture

public java.util.concurrent.CompletableFuture<java.util.List<T>> toCompletableFuture()

Specified by:

toCompletableFuture in interface PromisedValues<T>

Returns:

this as a CompletableFuture that returns the list of underlying values
