Method Detail

collectFailures

public MultiItemCombineIterable collectFailures()

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

Returns:

the current MultiItemCombineIterable

latestItems

public MultiItemCombineIterable 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.

Returns:

the current MultiItemCombineIterable

using

public <O> Multi<O> using(Function<List<?>,O> combinator)

Sets the combination logic as parameter and returns a Multi associating the items from the observed stream using this combinator.

Type Parameters:

O - the type of item produced by the returned Multi (the return type of the combinator)

Parameters:

combinator - the combination function, must not be null

Returns:

the new Multi
