Detailed Description

Abstract interface for signaling changed cluster members.

Its aim is to be derived from by the application writer. The concrete implementation can then be registered with the DiCE API and will after that be used by the DiCE library.

Note
Instances of this interface should not be created on the stack, since this might lead to premature destruction of such instances while still being in use by DiCE.

Member Function Documentation

 membership_callback()

virtual void mi::neuraylib::IWorker_node_callback::membership_callback ( IWorker_node_descriptor worker_descriptor,
bool  flag 
)
pure virtual

This function is called when a worker node joined or left the cluster.

It should return as soon as possible because it may block further network operations.

Parameters
worker_descriptorThe descriptor of the worker node joining or leaving.
flagtrue in case of a joining worker node , false in case of a leaving worker node.
