Method Detail

collectFailures

public MultiItemCombine3<T1,T2,T3> collectFailures()

Configures the combination to wait until all the streams to fire a completion or failure event before propagating a failure downstream.

Overrides:

collectFailures in class MultiItemCombineIterable

Returns:

the current MultiItemCombine3

latestItems

public MultiItemCombine3<T1,T2,T3> latestItems()

By default, the combination logic is called with one item of each observed stream. It waits until all the observed streams emit an item and call the combination logic. In other words, it associated the items from different stream having the same index. If one of the stream completes, the produced stream also completes.

With this method, you can change this behavior and call the combination logic every time one of one of the observed streams emit an item. It would call the combination logic with this new item and the latest items emitted by the other streams. It wait until all the streams have emitted at least an item before calling the combination logic.

If one of the stream completes before having emitted a value, the produced streams also completes without emitting a value.

Overrides:

latestItems in class MultiItemCombineIterable

Returns:

the current MultiItemCombine3

asTuple

public Multi<Tuple3<T1,T2,T3>> asTuple()

Returns:

the resulting Multi. The items are combined into a Tuple3<T1, T2, T3>.

using

public <O> Multi<O> using(Functions.Function3<T1,T2,T3,O> combinator)

Creates the resulting Multi. The items are combined using the given combinator function.

Type Parameters:

O - the type of item

Parameters:

combinator - the combinator function, must not be null

Returns:

the resulting Multi.
