buffer

public static <T> Multi<T> buffer(Multi<T> upstream,
                                  int size)

buffer

public Multi<T> buffer()

When the downstream cannot keep up with the upstream emissions, instruct to use an unbounded buffer to store the items until they are consumed.

Returns:

the new multi

buffer

public Multi<T> buffer(int size)

When the downstream cannot keep up with the upstream emissions, instruct to use a buffer of size size to store the items until they are consumed. When the buffer is full, a BackPressureFailure is propagated downstream and the upstream source is cancelled.

Parameters:

size - the size of the buffer, must be strictly positive

Returns:

the new multi

drop

public Multi<T> drop()

When the downstream cannot keep up with the upstream emissions, instruct to drop the item.

Returns:

the new multi

drop

public Multi<T> drop(Consumer<T> callback)

When the downstream cannot keep up with the upstream emissions, instruct to drop the item.

Parameters:

callback - a callback invoked when an item is dropped. The callback receives the item. Must not be null

Returns:

the new multi

dropPreviousItems

public Multi<T> dropPreviousItems()

When the downstream cannot keep up with the upstream emissions, instruct to drop all previously buffered items.

Returns:

the new multi
