Parameters

prefix

A UABrowsePathElementCollection object. The browse path element collection to be tested as a prefix.

Because the UABrowsePathElementCollection has an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection (containing a sequence of qualified names, assumed to form a relative browse path using "any hierarchical" forward references) in place of this parameter, and the corresponding OPC UA browse path element collection will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUAQualifiedNameCollection static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

The individual elements of the parameter value cannot be null (Nothing in Visual Basic).

Return Value

This method is pure, i.e. it does not have observable side effects.
