java.lang.Object

org.openjump.core.ui.plugin.tools.Add3DGeometryAttributesPlugIn.ZBoundedSubLineString

Enclosing class:

Add3DGeometryAttributesPlugIn

public static class Add3DGeometryAttributesPlugIn.ZBoundedSubLineString
extends java.lang.Object

Inner Class representing a sub-linestring where each end points is either

• an endpoint of the main LineString
• an interior point with a z value

Z characteristics as 3D length or slopes are computed on ZBoundedSubLineString

Methods

Modifier and Type	Method and Description
double	getLength2d()
double	getLength3d() Return the length3d of this substring if both start and end points have a z, length2d elseif.
double	getSlope() Return the signed slope of the sublinestring (dz/length2d) or NaN if it contains only one or z value.
double	getWeightedZ() Return : mean z * length2d if both ends of the linestring have a z z * length2d if only one end has a z NaN if substring end points don't have z values

Method Detail

getLength2d

public double getLength2d()

getLength3d

public double getLength3d()

Return the length3d of this substring if both start and end points have a z, length2d elseif.

getWeightedZ

public double getWeightedZ()

Return :
