public class ExecutionTimeAttributes
extends ExecutionAttributes

Container for decorator attributes that are provided to actors by a ExecutionAspect that schedules execution times. The ExecutionAspect decorates actors in a model with the attributes contained by this object.

Field Detail

executionTime

public Parameter executionTime

The executionTime parameter specifies the execution time of the decorated object. This means the time that the decorated actor occupies the decorator resource when it fires. This is a double that defaults to 0.0.

Constructor Detail

ExecutionTimeAttributes

public ExecutionTimeAttributes(NamedObj target,
                               Decorator decorator)
                        throws IllegalActionException,
                               NameDuplicationException

Constructor to use when editing a model.

Parameters:

target - The object being decorated.

decorator - The decorator.

Throws:

IllegalActionException - If the superclass throws it.

NameDuplicationException - If the superclass throws it.

ExecutionTimeAttributes

public ExecutionTimeAttributes(NamedObj target,
                               java.lang.String name)
                        throws IllegalActionException,
                               NameDuplicationException

Constructor to use when parsing a MoML file.

Parameters:

target - The object being decorated.

name - The name of this attribute.

Throws:

IllegalActionException - If the superclass throws it.

NameDuplicationException - If the superclass throws it.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

React to a change in an attribute. If the attribute is executionTime, check that it is non-negative.

Overrides:

attributeChanged in class ExecutionAttributes

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (not thrown in this base class).

canSimulateExecutionFor

public boolean canSimulateExecutionFor(NamedObj target)

Return whether the target can have an execution time that can be simulated. For instance, it does not make sense to simulate execution time of states in modal models, but it does make sense to monitor the execution of states such as entry times.

Parameters:

target - The object decorated with the attributes.

Returns:

True if execution target can have execution time.
