Detailed Description

Container Class for a Nodeset of OPC UA Nodes.

This class is used to store an imported OPC UA Addressspace (or parts of it) and provides a STL like interface to work with the data. The internal representation for data storage is a std::map of UaBase::BaseNodes but can change in future revisions. Therefore the public STL interface (iterators and standard operations like e.g. empty()) is provided.

This class implements the AbstractNodesetServices Interface which provides a more UA like way to interact with a Nodeset. This implementation is used to implement, for example the UaAbstractDictionaryReader interface in UaBase::AbstractNodesetExport .

Member Function Documentation

bool UaBase::Nodeset::deleteNode ( UaNodeId nodeId )

Delete a node from the Nodeset.

If there is a value allocated for this key, free the associated memory.

Parameters

nodeId The key to delete from the Nodeset.

UaUInt16Array UaBase::Nodeset::getNamespaceIndices ( const UaStringArray & nsUris ) const

Returns the namespace indices in the Nodeset's namespace table for the given namespace uris.

Parameters

nsUris a UaStringArray of namespace uris for which to retrieve the index in the Nodeset's namespace table.

Returns: a UaUInt16Array of namespace indices corresponding to the namespace uris

const UaStringArray & UaBase::Nodeset::getNamespaces ( ) const

Gets the namespaceArray of the Nodeset.

Returns: a reference to the UaStringArray containing the namespace uris of all namespaces currently present in the Nodeset

BaseNode * UaBase::Nodeset::newNode	(	UaNodeId	nodeId,
		OpcUa_NodeClass	nodeClass
	)

Allocates and inserts a new Nodeset member.

Parameters

nodeId	the nodeId of the new BaseNode
nodeClass	the nodeClass of the new BaseNode

Returns: a pointer to the newly allocated BaseNode

bool UaBase::Nodeset::remapNamespaces ( )

Map all namespace indices in Nodeset according to m_nsmap and adjust the namespacetable accordingly.

On Success m_nsmap will get cleared.

void UaBase::Nodeset::setNamespaces ( const UaStringArray & namespaceUris )

Sets the namespaceArray of the Nodeset.

Parameters

namespaceUris a UaStringArray containing the namespace uris of all namespaces present in the Nodeset
