Method Detail

getGeometryId

public short getGeometryId()

Description copied from class: LineString

Returns the geometry class id. This method is useful for geometry serialization.

Specified by:

getGeometryId in interface Geometry

Overrides:

getGeometryId in class LineString

Returns:

the geometry id.

pointOnLine

public Point pointOnLine(double interpolation)

This method finds the point being at a certain percentage of the path between the starting point and the final point.

Overrides:

pointOnLine in class LineString

Parameters:

interpolation - the interpolation expressed as a percentage (between 0 and 1)

Returns:

the reulsting point

getCenteredPoint

public Point getCenteredPoint()

Description copied from class: LineString

This method returns a point that is typically centered on the geometry. If the geometry is a point, the point is returned. If it is a line, a point on the curve interpolated at 50% is returned. If the geometry is a surface, the centroid is returned if it is inside the polygon, if not, a point inside the polygon (but likely not exactly in the center) will be returned. If the geometry is a collection, the method is called on the first part of the collection.

Specified by:

getCenteredPoint in interface Geometry

Overrides:

getCenteredPoint in class LineString

Returns:

a point likely at the center of the geometry

toString

public java.lang.String toString()

Description copied from interface: Geometry

Returns informations about the current geometry.

Specified by:

toString in interface Geometry

Overrides:

toString in class LineString

Returns:

informations about the current geometry.
