Method Detail

initialize

public void initialize()
                throws IllegalActionException

Initialize the component. This is invoked once after preinitialize() and again whenever the component needs to be reinitialized.

Specified by:

initialize in interface Component

Overrides:

initialize in class ComponentDirector

Throws:

IllegalActionException - If initialization cannot be completed.

letTimePass

public void letTimePass(double timeInterval,
                        boolean atomic)

Call fireAtRelativeTime() with the specified time interval and then suspend the calling thread. Make a record so that when this director gets fired at the requested time, the suspended thread is reawakened. The second argument, if true, requests that during this time interval, this actor not react to input events.

Parameters:

timeInterval - The time interval.

atomic - True to disable interrupts.

preinitialize

public void preinitialize()
                   throws IllegalActionException

Preinitialize the component. This is invoked exactly once per execution of a model, before any other methods in this interface are invoked.

Specified by:

preinitialize in interface Component

Overrides:

preinitialize in class ComponentDirector

Throws:

IllegalActionException - If preinitialization cannot be completed.

reactAt

public void reactAt(double time,
                    Component component)

Request that the react() method of the specified component be invoked at the specified time. The react() method will be passed a null argument. This method calls fireAt() and records the requesting component so that when the firing occurs it calls react() on that component.

Parameters:

time - The time at which to invoke react().

component - PtinyOSComponent The requesting component.

run

public void run()
         throws IllegalActionException

Execute the component. This is invoked after preinitialize() and initialize(), and may be invoked repeatedly.

Specified by:

run in interface Component

Overrides:

run in class ComponentDirector

Throws:

IllegalActionException - If the run cannot be completed.

wrapup

public void wrapup()
            throws IllegalActionException

Wrap up an execution. This method is invoked exactly once per execution of a model. It finalizes an execution, typically closing files, displaying final results, etc. If any other method from this interface is invoked after this, it must begin with preinitialize().

Specified by:

wrapup in interface Component

Overrides:

wrapup in class ComponentDirector

Throws:

IllegalActionException - If wrapup fails.
