public abstract class LineConvexSubset3D
extends LineSubset3D

Class representing a convex subset of a line in 3D Euclidean space. Instances need not be finite, in which case the start or end point (or both) will be null.

Method Detail

isInfinite

public abstract boolean isInfinite()

Return true if the line subset is infinite.

Returns:

true if the line subset is infinite.

isFinite

public abstract boolean isFinite()

Return true if the line subset is finite.

Returns:

true if the line subset is finite.

getStartPoint

public abstract Vector3D getStartPoint()

Get the start point for the line subset.

Returns:

the start point for the line subset, or null if no start point exists

getSubspaceStart

public abstract double getSubspaceStart()

Get the 1D start location of the line subset or Double.NEGATIVE_INFINITY if no start location exists.

Returns:

the 1D start location of the line subset or Double.NEGATIVE_INFINITY if no start location exists.

getEndPoint

public abstract Vector3D getEndPoint()

Get the end point for the line subset.

Returns:

the end point for the line subset, or null if no end point exists.

getSubspaceEnd
