Glossary
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.
Data Input Pin A connection point on the left side of an
object that permits data to flow into the object.
Data Output Pin A connection point on the right side of an
object that propagates data flow to the next object and
passes the results of the first object's operation on to the
next object.
