public class MOSFET
extends Object

Class draws a schematic MOSFET diagram using a Graphics context which is to be passed in as an argument. Class sets the drawing size, location of the diagram, and channel type (N or P). Get methods include querries for the (x,y) location of S, G, D, and Blk leads, the channel type, etc. Other public interfaces include moveTo(), clear(), etc.
