Function GetValueRank( _ ByVal endpointDescriptor As UAEndpointDescriptor, _ ByVal nodeDescriptor As UANodeDescriptor, _ ByRef valueRank As Integer, _ ByRef exception As Exception _ ) As Boolean
'Usage
Dim instance As IUAModelProvider Dim endpointDescriptor As UAEndpointDescriptor Dim nodeDescriptor As UANodeDescriptor Dim valueRank As Integer Dim exception As Exception Dim value As Boolean value = instance.GetValueRank(endpointDescriptor, nodeDescriptor, valueRank, exception)
bool GetValueRank( UAEndpointDescriptor endpointDescriptor, UANodeDescriptor nodeDescriptor, out int valueRank, out Exception exception )
bool GetValueRank( UAEndpointDescriptor^ endpointDescriptor, UANodeDescriptor^ nodeDescriptor, [Out] int valueRank, [Out] Exception^ exception )
Parameters
- endpointDescriptor
- Endpoint descriptor. Identifies the OPC-UA server.
- nodeDescriptor
- Node descriptor. Identifies the node in OPC server's address space.
- valueRank
- The value rank. Valid when exception is equal to
null
. - exception
- Contains information about the error encountered while interrogating the model, or
null
if the operation was successful.
Return Value
Returns
true
if the model provider is responsible for (has knowledge about) the specified node; return false
otherwise.
