opcua::PluginAdapter< T > Class Template Reference

#include <pluginadapter.hpp>

Detailed Description

template<typename T>
class opcua::PluginAdapter< T >

Base class to implement plugin adapters.

Plugin adapters will provide a different (modern) interface for open62541's native plugins. For example AccessControlBase is the plugin adapter for UA_AccessControl.

The native plugin is created via the PluginAdapter::create function. The PluginAdapter::clear function is used to clear the created plugin after usage. Usually the native plugin carries a void* context pointer which will refer back to the plugin adapter. Make sure that the plugin adapter outlives the native plugin to avoid dangling pointers.

Template Parameters

T	Type of the native plugin, e.g. UA_AccessControl
