Parameters

predicate: The predicate to filter role permissions. It is a function that takes a OpcLabs.EasyOpc.UA.UARolePermissions object as input and returns a boolean indicating whether the object should be included in the filtered result.
The value of this parameter cannot be null (Nothing in Visual Basic).

Return Value

A new UAPermissionAssignment instance containing only the role permissions that match the specified predicate.

This method never returns null (Nothing in Visual Basic).
