as the source network variable. This
method is used to construct an
interface object for a host application.
interfaceObject The Interface object to be acted on.
nvName A String containing the name of the
added network variable.
The name specified in this parameter
can be a maximum of 16 characters,
and it must not start with a number.
In addition, it cannot include square
brackets ([]), commas (,), or periods (.).
Once the NetworkVariable object has
been created, it may be renamed
subject to the restrictions of the Name
property.
The name specified in this method
may subsequently be retrieved using
the ProgrammaticName property.
sourceNvObj The NetworkVariable object for which
a complementary network variable is
created.
Added to API Prior to LNS Release 3.0.
AddComplementaryNvEx
Summary Creates a NetworkVariable object that is complementary to a
specified target network variable, and adds the
complementary network variable to the specified Interface
object .
This method differs from AddComplementaryNv method
in that it allows you to set options .
A network variable is complementary to another network
variable if it uses the same type and configuration (for
example, service type, authentication setting, default value,
polling attribute) but opposite direction (two network
variables that may be bound together). This method is used
to construct an Interface object for a host application. This
method is typically used to create an input network variable
that is subsequently bound to a target output network
variable that is to be monitored
This method should only be called on a custom Interface
object that is contained by a device that supports dynamic
network variables.
Availability Local, full, and lightweight clients.
