'Declaration
<NotNullAttribute()> Function BrowseAccessPaths( _ ByVal serverDescriptor As Object, _ ByVal nodeDescriptor As Object _ ) As Object()
'Usage
Dim instance As _EasyDAClient Dim serverDescriptor As Object Dim nodeDescriptor As Object Dim value() As Object value = instance.BrowseAccessPaths(serverDescriptor, nodeDescriptor)
[NotNull()] object[] BrowseAccessPaths( object serverDescriptor, object nodeDescriptor )
[NotNull()] array<Object^>^ BrowseAccessPaths( Object^ serverDescriptor, Object^ nodeDescriptor )
Parameters
- serverDescriptor
- The OPC server involved in the operation.
Because the OpcLabs.EasyOpc.ServerDescriptor has an implicit conversion from System.Guid, System.String and OpcLabs.EasyOpc.ServerElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a GUID (representing the CLSID of the server), a string (representing the so-called OPC server descriptor string, such as a ProgID or the URL of the server), or a OpcLabs.EasyOpc.ServerElement object (result from OPC browsing), in place of this parameter, and the corresponding OPC server descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.ServerDescriptor.FromGuid, OpcLabs.EasyOpc.ServerDescriptor.FromString or OpcLabs.EasyOpc.ServerDescriptor.FromServerElement static method instead.
The value of this parameter cannot be
null
(Nothing
in Visual Basic). - nodeDescriptor
- Descriptor of the node for which the access paths will be browsed.
Because the OpcLabs.EasyOpc.DataAccess.DANodeDescriptor has an implicit conversion from System.String and OpcLabs.EasyOpc.DataAccess.AddressSpace.DANodeElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the qualified name of the node), or a OpcLabs.EasyOpc.DataAccess.AddressSpace.DANodeElement object (result from OPC browsing), in place of this parameter, and the corresponding OPC DA node descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.DataAccess.DANodeDescriptor.FromString or OpcLabs.EasyOpc.DataAccess.DANodeDescriptor.FromDANodeElement static method instead.
The value of this parameter cannot be
null
(Nothing
in Visual Basic).
Return Value
This method never returns null
(Nothing
in Visual Basic).
The individual elements of the returned value are never null
(Nothing
in Visual Basic).
