Cvb::OpcUa Namespace Reference

Root namespace for the OpcUA tool. More...

Classes

class  BaseNode
 An OPCUA BaseNode. This is the base for all other node classes. For instantiation of a specific node type use one of the specific subclasses. There is no public interface to create a BaseNode. More...
 
class  BrowseFilter
 The BrowseFilter serves to specify the parameter of a browse operation on an OPCUA node object. More...
 
class  Client
 An OPCUA Client object. This class handles the client side of the OPCUA client/server interaction. More...
 
class  FloatNode
 A FloatNode object provides an interface for storage and manipulation of floating point numbers. More...
 
class  IntegerNode
 A Node with integer values provides an interface for storage and manipulation of integer (default int representation) numbers. More...
 
class  MethodNode
 An OPCUA method node object to call remote procedures. More...
 
class  MethodNodeArgument
 An OPCUAMethodNodeArgument is a helper class to manage arguments of a method node. More...
 
class  NodeID
 An OPCUA NodeID object. NodeIDs provide a unique identifier for OPCUA nodes, i.e. they help with node creation, addition to servers, retrieving from servers etc.. More...
 
class  ObjectNode
 An OPCUA Object Node object. This is the "base" of many more complex node. However the defining feature is to create a ObjectNode from a OPCUA TypeDefinition. Example: A ObjectNode can be created with Namespace0NodeId of "FolderType", i.e. the creation for a folder. More...
 
class  OpcUaException
 Special runtime exception to carry a native error code. More...
 
class  Server
 An OPCUA server object. More...
 
class  StringNode
 A node object with string values, provides an interface for storage and manipulation of strings (default std::string or std::wstring representation). More...
 
class  Subscription
 An OPCUA Subscribe serves to monitor OPCUA variables (from a client) and provides a callback mechanism for changes. More...
 
class  VariableNode
 An OPCUA VariableNode object. It handles the data modeling acording to the OPCUA specification. More...

Detailed Description

Root namespace for the OpcUA tool.

This namespace groups all parts of the C++ interface to the classic CVB OPCUA API. The classes directly within this namespace are usually your entry point when programming.

Examples
Note
All types under this namespace have unique names, therefore all types are mapped to this namespace for convenience.
