IVI-COM Parameter General Editor

Name

Name of the parameter. Parameter names must start with a capital letter and can contain only alphanumeric characters.

Type

Data type of the method.

If an array is desired, append opening and closing square brackets ([]) to the type name. For example, to specify an array of double, enter Double[].

Tip

The following syntax can be used in the Type text box to create a new enum type and use that enum as the type all in one operation:

new enum TriggerSource; Internal = 2, External = 0x15, Software = 47

See the topic Defining New Data Types Inline for more information on this feature.

Direction

Choose Input to specify an input parameter.

Choose Output to specify an output parameter.

Choose Input/Output to specify an input/output parameter.

Important

As per the IVI specifications, Nimbus generates [in, out] in the IDL method signature if either Output or Input/Output is specified. This is as per the IVI specifications. However, it is important to properly indicate the “logical” direction of the parameter here. See the topic Understanding Parameter Direction for a detailed discussion of output parameters in IVI-COM drivers.
