      Modifier and Type Method Description
      Multi<T> buffer()
      When the downstream cannot keep up with the upstream emissions, instruct to use a bounded buffer of the default size to store the items until they are consumed.
      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.
      Multi<T> bufferUnconditionally()
      When the downstream cannot keep up with the upstream emissions, instruct to use an unbounded buffer to store the items until they are consumed.
      Multi<T> drop()
      When the downstream cannot keep up with the upstream emissions, instruct to drop the item.
      Multi<T> dropPreviousItems()
      When the downstream cannot keep up with the upstream emissions, instruct to drop all previously buffered items.

      • drop

        @CheckReturnValue
public Multi<T> drop()
        When the downstream cannot keep up with the upstream emissions, instruct to drop the item.
        Returns:
        the new multi

      • buffer

        @CheckReturnValue
public Multi<T> buffer()
        When the downstream cannot keep up with the upstream emissions, instruct to use a bounded buffer of the default size to store the items until they are consumed.
        Returns:
        the new multi

      • buffer

        @CheckReturnValue
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

      • bufferUnconditionally

        @CheckReturnValue
public Multi<T> bufferUnconditionally()
        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

      • dropPreviousItems

        @CheckReturnValue
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
