Interface PausableMulti

public interface PausableMulti
Interface for controlling a pausable Multi stream.

This interface defines the contract for pausing and resuming demand propagation in a reactive stream. Implementations of this interface are typically bound to a DemandPauser to provide external control.

This is an internal interface used by the demand pausing operator. Users should interact with DemandPauser instead.
