Public Types | |
using | output_type = T |
The type of observed values. | |
Public Member Functions | |
virtual coordinator * | ctx () const noexcept=0 |
Returns the coordinator that executes this flow operator. | |
virtual disposable | subscribe (observer< T > what)=0 |
Subscribes a new observer to the operator. | |
![]() | |
virtual void | ref_coordinated () const noexcept=0 |
Increases the reference count of the coordinated. | |
virtual void | deref_coordinated () const noexcept=0 |
Decreases the reference count of the coordinated and destroys the object if necessary. | |
