Adds the given Observer to this Subject's list of Observers, so that the Observer
will be notified of changes in this Subject. An Observer may call Subject.addObserver
during its observe method.

Notifies all Observers that this Subject has changed by calling observe on each Observer.
An Observer may call addObserver or removeObserver during its observe
method.

Removes the Observer from this Subject's list of Observers. An Observer may
call removeObserver during its observe method.

Protected setSets whether this Subject will broadcast events, typically used to temporarily disable broadcasting. Intended to be used in situations where a subclass overrides a method that broadcasts an event. This allows the subclass to prevent the superclass broadcasting that event, so that the subclass can broadcast the event when the method is completed.

Returns a minimal string representation of this object, usually giving just identity information like the class name and name of the object.
For an object whose main purpose is to represent another Printable object, it is
recommended to include the result of calling toStringShort on that other object.
For example, calling toStringShort() on a DisplayShape might return something like
this:
DisplayShape{polygon:Polygon{'chain3'}}
a minimal string representation of this object.
Watch a Parameter and when it changes note that there was a discontinuous change in potential and total energy.

Static loadGenerated using TypeDoc
Abstract base class that creates the standard set of views, graphs and controls which are common to applications that run a RigidBodySim, ImpulseSim, or ContactSim,
Creates instance objects such as the simulation and display objects; defines regular expressions for easy Terminal scripting of these objects using short names instead of fully qualified property names.
The constructor takes an argument that specifies the names of the HTML elementId's to look for in the HTML document; these elements are where the user interface of the simulation is created. This allows for having two separate simulation apps running concurrently on a single page.
No global variables are created other than two root global variables: the
myphysicslabglobal holds all of the myPhysicsLab classes; and a global variable is created for this application instance. This application global is created outside of this file in the HTML where the constructor is called. The name of that global variable holding the application is passed to defineNames method so that short-names in scripts can be properly expanded.
