public class NonStrictDisplay
- extends Display
Display the status and value of input tokens in a text area.
Display the values of the tokens arriving on the input channels along
with the associated time in a text area on the screen. If the value is
undefined or known to be absent, that information is indicated instead.
Each input token is written on a separate line. The input type can be
of any type. If the input happens to be a StringToken,
then the surrounding quotation marks are stripped before printing
the value of the token. Thus, string-valued tokens can be used to
generate arbitrary textual output, at one token per line.
Tokens are read from the input only in
the postfire() method, to allow them to settle in domains where they
converge to a fixed point.

NonStrictDisplay
public NonStrictDisplay(CompositeEntity container,
java.lang.String name)
throws IllegalActionException,
NameDuplicationException
- Construct an actor with an input multiport of type GENERAL.
- Parameters:
container - The container.name - The name of this actor.
- Throws:
IllegalActionException - If the entity cannot be contained
by the proposed container.
NameDuplicationException - If the container already has an
actor with this name.
isStrict
public boolean isStrict()
- Return false. This actor displays "undefined" when the input
receiver has status unknown.
- Specified by:
isStrict in interface Executable- Overrides:
isStrict in class AtomicActor
- Returns:
- False.
postfire
public boolean postfire()
throws IllegalActionException
- Read at most one token from each input channel and display its
string value along with the current time on the screen. Each
value is terminated with a newline character.
- Specified by:
postfire in interface Executable- Overrides:
postfire in class Display
- Returns:
- True if execution can continue into the next iteration.
- Throws:
IllegalActionException - If there is no director.
