Constructors

o ScalarMultiplier1 
 public ScalarMultiplier1(Rectangle d,
                          double scalar,
                          boolean fixed)
Parameters:
d - the relative rectangle the Pantograh should be drawn in. The origin is set to the middle of this rectangle.
scalar - the parameter of multiplication.
fixed - Determines if this object should have 2 input joints or one anchor pinned at relative(0,0).

Methods

o setScalar 
 void setScalar(double scalar)
Used to translate between the parameter used by the object (allways >1) and the scalar used to compute the output joint location. the translation is done by setting different input joints.

Parameters:
scalar - the new scalar to set to.

o forceInputJoints 
 public Coordinate[] forceInputJoints(Coordinate inputs[])
Parameters:
inputs - an array of 2 Coordinate objects. If the Pantograph is fixed the first location is overlooked.
Returns:
a one size array containing the location of the output joint.

FunctionalLinkage
o setInputJoints 
 public Coordinate[] setInputJoints(Coordinate inputJoints[]) throws MachineException
Parameters:
inputJoints - an array of 2 Coordinate objects. If the Pantograph is fixed the first location is overlooked.
Throws: MachineException
if the new input location is not valid.
