Class LeanBodyMass

java.lang.Object
  metab.LeanBodyMass

All Implemented Interfaces:

java.io.Serializable

public class LeanBodyMass

extends java.lang.Object

implements java.io.Serializable

The LeanBodyMass class simulates the Lean Body Mass compartment in the Compartmental model. The Lean Body Mass handles the majority of the actual metabolism of ethanol in the human body, mainly through the liver. Once the ethanol has been metabolized, the user should remove it from the system using the addContents method. No addLiquid method is necessary for this class because the liquid is the aqueous portion of the subject's body. This Total Body Water is a required argument during class construction. The TBW must be calculated or measured outside of the class (externally). Also required during construction is the amount of ethanol (g), the subject's previous drinking history (an integer value consisting of one of the constants defined in NMSubject, and, optionally, a description (label) of the compartment.
