• #### calculateBounds

`protected void calculateBounds()`
The bounds are determined by including all points that determine the polyline. Sample points are taken on each line segment in order to take the geodesic characteristics into account. Since the maximum or minimum may be missed this way a small extension of the bounds is applied.
Specified by:
`calculateBounds` in class `ALcd2DEditableLine`

`ILcdShape.contains2D(double, double)`
• #### contains2D

```public boolean contains2D(double x,

`x` - the x coordinate of the point.
`y` - the y coordinate of the point.
Returns:
the boolean result of the containment test.
• #### clone

`public Object clone()`
Creates and returns a copy of this object.

The two editable points of the line are cloned.

The contained ellipsoid is copied without being cloned.

The cache, the bounds and the focus point are not copied or cloned at all, but recalculated when needed.

Overrides:
`clone` in class `ALcd2DEditableLine`
`Object.clone()`

• #### hashCode

`public int hashCode()`
Description copied from class: `ALcdShape`
The hash code of this shape is the hash code of its class, in order to be consistent with the `ALcdShape.equals(Object)` method. Extensions should refine this implementation, based on their properties.

• #### getEndPoint

`public ILcdPoint getEndPoint()`
Description copied from interface: `ILcdCurve`
Retrieves the end point of the curve.

This is equivalent to `computePointSFCT(1)`.

• #### getEndTangent2D

`public double getEndTangent2D()`
Description copied from interface: `ILcdCurve`
Returns the angle of the curve's tangent at the end point, in degrees counterclockwise from the direction at 3 o'clock.

The tangent orientation is from the end point, away from the curve before it.

This is the same as `getTangent2D(1)`.

Returns the interpolation method used by this curve.

A set of predefined constants are defined in this interface, which are used by the default `ILcdCurve` implementations provided by LuciadLightspeed.

Custom implementations can define their own constants, and use them to interpret the interpolation of the curve.

`getInterpolation` in interface `ILcdCurve`
Returns:
the interpolation method used by this curve.

• When `aParam1 == aParam2`, the length is 0.
• When `aParam1 == 0 and aParam2 == 1`, the length is the whole length of the curve.
• When `aParam1 > aParam2`, the length is (`aParam1 to 1`) + (`0 to aParam2`).
Specified by:
`getLength2D` in interface `ILcdCurve`

This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.

Specified by:
`getLineSegmentIntersectionCount` in interface `ILcdCurve`
