Detailed Description

Callback interface for user specific browse result manipulation.

This interface needs to be registered with the NodeManagerUaNode using the method NodeManagerUaNode::registerBrowseUaNodeCallback. The methods of this interface allow the product specific implementation to manipulate the results of browse calls to the NodeManagerUaNode for example to limit browse access to nodes based on the user logged on for the session.

virtual OpcUa_Boolean BrowseUaNodeCallback::browseNode ( Session *  pSession, const BrowseContext &  browseContext, UaNode *  pNodeToBrowse  ) const

pure virtual

This method tells the NodeManagerUaNode whether the requested node pNodeToBrowse should return any browse result.

Returns

OpcUa_True if the user is allowed to browse the node and OpcUa_False if not.

Parameters

[in]	pSession	Session context for the browse call. A user defined derived class must contain the user context.
[in]	browseContext	Browse context for the browse call.
[in]	pNodeToBrowse	UaNode interface of the node requested to be browsed.

void BrowseUaNodeCallback::modifyBrowseResultNode ( Session *  pSession, UaNode *  pResultNode, OpcUa_ReferenceDescription &  browseResult  ) const

virtual

This optional method allows the callback to modify the node results e.g.

the DisplayName language.

Parameters

[in]	pSession	Session context for the browse call. A user defined derived class must contain the user context.
[in]	pResultNode	UaNode interface of the node to be returned by the browse call.
[in,out]	browseResult	Browse result for the node. The result can be modified by the method.

virtual OpcUa_Boolean BrowseUaNodeCallback::returnBrowseResultNode ( Session *  pSession, const BrowseContext &  browseContext, UaNode *  pNodeToBrowse, const UaNodeId &  referenceTypeId, UaNode *  pResultNode  ) const

pure virtual

This method tells the NodeManagerUaNode whether the result node should be returned to the client.

Returns

OpcUa_True if the node should be returned and OpcUa_False if not.

Parameters

[in]	pSession	Session context for the browse call. A user defined derived class must contain the user context.
[in]	browseContext	Browse context for the browse call.
[in]	pNodeToBrowse	UaNode interface of the browsed node.
[in]	referenceTypeId	The reference type NodeId from the browsed node to the result node.
[in]	pResultNode	UaNode interface of the node requested to be returned by the browse call.
