Detailed Description

Abstract interface for signaling a change of the cluster application head node.

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.

See also: mi::neuraylib::INode_manager_cluster::get_head_node to retrieve the cluster head node.

Member Function Documentation

^◆ head_node_callback()

virtual void mi::neuraylib::IHead_node_callback::head_node_callback ( IWorker_node_descriptor * worker_descriptor )

pure virtual

This function is called when a cluster node becomes cluster head node.

This should not be confused with the head node in TCP networking as it is unrelated.

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

Parameters

worker_descriptor The descriptor of the cluster head node.
