public class Break
extends ControlActor

An actor that implements a control break. If this actor is reached, control returns to the caller. This block has no functionality.

Break is a ControlActor, meaning that it keeps a list of enabled output ports. However, the Break actor has no output ports, so this list is always empty here.

Constructor Detail

Break

public Break(CompositeEntity container,
             java.lang.String name)
      throws NameDuplicationException,
             IllegalActionException

Create a new actor in the specified container with the specified name. The name must be unique within the container or an exception is thrown. The container argument must not be null, or a NullPointerException will be thrown.

Parameters:

container - The container.

name - The name of this actor within the container.

Throws:

IllegalActionException - If this actor cannot be contained by the proposed container (see the setContainer() method).

NameDuplicationException - If the name coincides with an entity already in the container.

Method Detail

preinitialize

public void preinitialize()
                   throws IllegalActionException

Add a check for an unconnected input port. If the port is unconnected, set the type, so that the type will not resolve to unknown Can't use setAtLeast in the constructor, because the input could be any type, and booleans/integers/reals do not have a common base type other than unknown

Specified by:

preinitialize in interface Initializable

Overrides:

preinitialize in class AtomicActor

Throws:

IllegalActionException - Not thrown here
