Description

Abstract interface for signaling changed cluster properties. Its aim is to be derived from by the application writer. The concrete implementation can then be registered with the neuray API and will after that be used by the .

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 .

virtual void mi::​neuraylib::​ICluster_property_callback::property_callback( const ICluster_descriptor* cluster_descriptor, const char* changed_property_name) [pure virtual]

This function is called when a cluster property change was communicated. It should return as soon as possible because it may block further network operations.

Parameters

cluster_descriptor
The descriptor of the cluster, containing all properties.
changed_property_name
The name of the changed property. This value is NULL if the callback is triggered to communicate the current set of properties instead of a property change.
