Class SpacePath

java.lang.Object

org.lcsim.spacegeom.SpacePointVector

org.lcsim.spacegeom.SpacePath

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

CartesianPath, CylindricalPath, SphericalPath

Deprecated.

this class does not offer additional functionality to SpacePointVector

@Deprecated
public class SpacePath
extends SpacePointVector

A differential path element vector ds in Cartesian, cylindrical or spherical coordinates. It is constructed using a subclass and then elements can be fetched for any of these coordinate systems. The stored vector can also include scalar quantities. Typical applications include velocity ds/dt and direction ds/d|s|.

Transformations (translations, rotations, etc) are not provided. It is expected these will be carried out by external functions which return new SpacePath objects.

Three orthogonal coordinate systems are:

• Cartesian: (x, y, z)
• Cylindrical: (rxy, phi, z)
• Spherical: (rxyz, theta, phi) .

These coordinates may be obtained via the space point interface.

The corresponding path element vectors are:

• Cartesian: (dx, dy, dz)
• Cylindrical: (drxy, rxy*dphi, dz)
• Spherical: (drxyz, rxyz*dtheta, rxy*dphi) .

These elements may be accessed via the usual space vector interface (v_x(), v_y(), ...) or via the methods defined here.
