## Detailed Description

The main interface that any VMS Plugin implements. The plugin's dynamic library should export only an extern-C function with the name and prototype defined in this interface, which acts as a getter/factory for a single object implementing this interface.

The only object of this class is created by a Server on its start, and is destroyed (via releaseRef()) on the Server shutdown.

All methods are guaranteed to be called without overlapping even if from different threads (i.e. with a guaranteed barrier between the calls), thus, no synchronization is required for the implementation.

## Member Typedef Documentation

## ◆ EntryPointFunc

typedef IPlugin*(* nx::sdk::IPlugin::EntryPointFunc) ()

Prototype of a plugin entry point function.

## Member Function Documentation

## ◆ setUtilityProvider()

virtual void nx::sdk::IPlugin::setUtilityProvider | ( | IUtilityProvider * | utilityProvider | ) |
| pure virtual

Provides an object which the plugin can use for calling back to access some data and functionality provided by the process that uses the plugin.

For details, see the documentation for IUtilityProvider.

Implemented in nx::sdk::analytics::Plugin.

## Member Data Documentation

## ◆ kEntryPointFuncName

constexpr const char* nx::sdk::IPlugin::kEntryPointFuncName = "createNxPlugin"
| static
