LocationIndexOfPoint class
Computes the {@link LinearLocation} of the point on a linear {@link Geometry} nearest a given {@link Coordinate}. The nearest point is not necessarily unique; this class always computes the nearest point closest to the start of the geometry.

Methods
-
indexOf(
Coordinate inputPt) → LinearLocation - Find the nearest location along a linear {@link Geometry} to a given point.
-
indexOfAfter(
Coordinate inputPt, LinearLocation minIndex) → LinearLocation -
Find the nearest {@link LinearLocation} along the linear {@link Geometry}
to a given {@link Coordinate}
after the specified minimum {@link LinearLocation}.
If possible the location returned will be strictly greater than the
minLocation. If this is not possible, the value returned will equalminLocation. (An example where this is not possible is when minLocation =end of line). -
indexOfFromStart(
Coordinate inputPt, LinearLocation? minIndex) → LinearLocation -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

toString(
