Class AbstractInertiaProperty

java.lang.Object

fr.cnes.sirius.patrius.assembly.properties.AbstractInertiaProperty

All Implemented Interfaces:

IPartProperty, IInertiaProperty

Direct Known Subclasses:

InertiaCylinderProperty, InertiaParallelepipedProperty, InertiaSimpleProperty, InertiaSphereProperty

public abstract class AbstractInertiaProperty
extends Object
implements IInertiaProperty

This class is the abstract class for all inertia properties : those properties can provide the inertia matrix and mass center of the part. All of them shall extend it to assure they have the same "PropertyType"

Constructor Detail

AbstractInertiaProperty

protected AbstractInertiaProperty(Vector3D massCenter,
                                  Matrix3D inertiaMatrix,
                                  MassProperty mass)

Constructor for the abstract inertia property.

Parameters:

massCenter - the mass center

inertiaMatrix - the inertia matrix

mass - the mass property associated to this part

AbstractInertiaProperty

protected AbstractInertiaProperty(Vector3D massCenter,
                                  Matrix3D inertiaMatrix,
                                  Vector3D inertiaReferencePoint,
                                  MassProperty mass)

Constructor for the abstract inertia property. The inertia matrix is expressed with respect to a point that can be different from the mass center.

Parameters:

massCenter - the mass center

inertiaMatrix - the inertia matrix

inertiaReferencePoint - the point with respect to the inertia matrix is expressed (in the part frame)

mass - the mass property associated to this part
