Constructor Detail

ZenoDelay

public ZenoDelay()
          throws IllegalActionException,
                 NameDuplicationException

Construct a ZenoDelay actor with no container and a name that is an empty string.

Throws:

IllegalActionException

NameDuplicationException

ZenoDelay

public ZenoDelay(Workspace workspace)
          throws IllegalActionException,
                 NameDuplicationException

Construct a ZenoDelay actor with the specified workspace and no name.

Parameters:

workspace - The workspace for this ZenoDelay actor.

Throws:

IllegalActionException

NameDuplicationException

ZenoDelay

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

Construct a ZenoDelay actor with the specified container and name.

Parameters:

container - The container of this actor.

name - The name of this actor.

Throws:

IllegalActionException - If the constructor of the superclass throws an IllegalActionException.

NameDuplicationException - If the constructor of the superclass throws a NameDuplicationException .

Method Detail

getDelay

public double getDelay()
                throws IllegalActionException

While the current time is less then 50.0, return the delay value as specified in the super class. After the current time has exceeded 50, return a delay value of 0.001 for 1000 firings. After the 1000 firings are complete, resume returning the super class delay value.

Overrides:

getDelay in class FeedBackDelay

Returns:

The delay value depending upon whether time has exceeded 50.0.

Throws:

IllegalActionException - If there is a problem reading the delay token.
