Method Detail

tension

public double tension()

Description copied from interface: ITensionI

tension is a coefficient to convert distance of two points to amount of force.

tension

public IStraightener tension(double tension)

Description copied from interface: ITensionI

tension is a coefficient to convert distance of two points to amount of force.

Description copied from interface: ITensionI

if constantTension is true, amount of force is always constant and it's equals to tension. Only direction of force changes. But if the distance is zero, force is also zero.

Specified by:

constant in interface ITensionI

constant

public IStraightener constant(boolean cnst)

Description copied from interface: ITensionI

if constantTension is true, amount of force is always constant and it's equals to tension. Only direction of force changes. But if the distance is zero, force is also zero.

Specified by:
