Glossary 531
Component
A single instrument function or measurement value in a VEE instrument
panel or component driver. For example, a voltmeter driver contains
components that record the range, trigger source, and latest reading.
Component Driver
An instrument control object that reads and writes values to components
you specifically select. Use component drivers to control an instrument
using a driver by setting the values of only a few components at a time.
(Component drivers do not support coupling.)
Container
See Data Container.
Context
A level of the work area that can contain other levels of work areas (such
as nested
UserObjects), but is independent of them.
Cursor
A pointer (caret) in an entry field that shows where alphanumeric data
will appear when you type information from the keyboard.
Cut Buffer
The buffer that holds objects that you cut or copy. You can then paste the
object back into the work area with the
Paste toolbar button
(
Edit ⇒ Paste).
Data Container
The data package that is transmitted over lines and is processed by
objects. Each data container contains data and the data type, data shape,
and mappings (if any).
Data Flow
The flow of data through and between VEE objects. Data flows from left
to right through objects, but an object does not execute until it has data on
all of its data input pins. Data is propagated from the data output pin of
one object to the data input pin of the next object. Data flow is the chief
factor that determines the execution of a VEE program.
