Class PhysicalObject

java.lang.Object

  +--feynman.framework.system.PhysicalObject

Direct Known Subclasses:

CartesianObject

public abstract class PhysicalObject

extends java.lang.Object

The class is really just a symbolic name that means more to physicists than the default Java Object class name means. It also helps to avoid confusion with the System class by establishing the semantic pattern in the framework of PhysicalObject and its counterpart PhysicalSystem. It does provide its sub-classes with an identifier mechanism and and equals method based on the unique identifier. This is useful for systems that contain many objects.
