Field Detail

active

public Parameter active

A Boolean parameter that determines whether this debugger is active.

Constructor Detail

EventQueueDebugger

public EventQueueDebugger(NamedObj container,
                          java.lang.String name)
                   throws NameDuplicationException,
                          IllegalActionException

Construct an attribute with the given container and name. If an attribute already exists with the same name as the one specified here, that is an instance of class SingletonAttribute (or a derived class), then that attribute is removed before this one is inserted in the container.

Parameters:

container - The container.

name - The name of this attribute.

Throws:

IllegalActionException - If the attribute cannot be contained by the proposed container.

NameDuplicationException - If the container already has an attribute with this name, and the class of that container is not SingletonAttribute.

Method Detail

addInitializable

public void addInitializable(Initializable initializable)

Do nothing.

Specified by:

addInitializable in interface Initializable

Parameters:

initializable - Not used.

See Also:

Initializable.removeInitializable(Initializable)

initialize

public void initialize()
                throws IllegalActionException

Do nothing.

Specified by:

initialize in interface Initializable

Throws:

IllegalActionException - Not thrown in this class.

insertActor

public void insertActor(int position,
                        Time time,
                        Actor actor,
                        Token arguments)

Invoked when an actor is inserted into the event queue.

Specified by:

insertActor in interface EventQueueDebugListener

Parameters:

position - The position at which the actor is inserted.

time - The time at which the actor is scheduled to fire.

actor - The actor.

arguments - Arguments to the actor, which must be either an ArrayToken or a RecordToken, or null.

insertEvent

public void insertEvent(int position,
                        Time time,
                        Event event,
                        Token arguments)

Invoked when an event is inserted into the event queue.

Specified by:

insertEvent in interface EventQueueDebugListener

Parameters:

position - The position at which the event is inserted.

time - The time at which the event is scheduled to fire.

event - The event.

arguments - Arguments to the event, which must be either an ArrayToken or a RecordToken, or null.

preinitialize

public void preinitialize()
                   throws IllegalActionException

Add this attribute as a debug listener to the director.

Specified by:

preinitialize in interface Initializable

Throws:

IllegalActionException - Not thrown in this class.

removeEvent

public void removeEvent(int position,
                        boolean isCancelled)

Invoked when an event or actor is removed from the event queue.

Specified by:

removeEvent in interface EventQueueDebugListener

Parameters:

position - The position of the event or actor.

isCancelled - Whether the removal is due to cancellation or successful processing.

removeInitializable

public void removeInitializable(Initializable initializable)

Do nothing.

Specified by:

removeInitializable in interface Initializable

Parameters:

initializable - Not used.

See Also:

Initializable.addInitializable(Initializable)

setContainer

public void setContainer(NamedObj container)
                  throws IllegalActionException,
                         NameDuplicationException

Set the container and register this as an initializable in the container.

Overrides:

setContainer in class SingletonAttribute

Parameters:

container - The container

Throws:

IllegalActionException - If this attribute is not of the expected class for the container, or it has no name, or the attribute and container are not in the same workspace, or the proposed container would result in recursive containment.

NameDuplicationException - If the container already has an attribute with the name of this attribute that is of class SingletonConfigurableAttribute.

See Also:

Attribute.getContainer()

wrapup

public void wrapup()
            throws IllegalActionException

Remove this attribute from the list of debug listeners in the director.

Specified by:

wrapup in interface Initializable

Throws:

IllegalActionException - Not thrown in this class.
