   +----primitives.machines.Adder
public class Adder
extends Object
implements FunctionalLinkage
An Adder Linkages is composed by two ScalarMultiplier Linkages; The first preforms the computation: output=(input1+input2)/2. The second preforms the computation: output=2*input The Adder does not inherit from Machine, instead it manipulates 2 ScalarMultiplier1 objects Which are its members.

See Also:
FunctionalLinkage, ScalarMultiplier1

Variable Index

o a2scalar
The object preforming multiplication by 2 initialized with one input joint.
o activeJoint
Stores the active joint (the joint the mouse pointer is over)
o average
The object preforming the average computation initialized with 2 input joints.
o def
o inputs
A copy of the 2 input joints.
o tempJoints
Used for storing a backup of the locations of one of the ScalarMultiplier1 members

Constructor Index

Variables

o average 
 ScalarMultiplier1 average
The object preforming the average computation initialized with 2 input joints.

See Also:
ScalarMultiplier1
o a2scalar 
 ScalarMultiplier1 a2scalar
The object preforming multiplication by 2 initialized with one input joint.

o tempJoints 
 Coordinate tempJoints[]
Used for storing a backup of the locations of one of the ScalarMultiplier1 members

o inputs 
 Coordinate inputs[]
A copy of the 2 input joints. This is a redondence field since The ScalarMultiplier1 class defines this field too.

o activeJoint 
 int activeJoint
Stores the active joint (the joint the mouse pointer is over)

o def 
 static final String def

Constructors

o Adder 
 public Adder(Rectangle d)
Parameters:
d - the rectangle to draw the Adder in. The 2 ScalarMultipliers are initialized with d
