intersects spatial relationship predicate for a target PreparedLineString relative to all other Geometry classes.
Uses short-circuit tests and indexing to improve performance.

This could be optimized by using the segment index on the lineal target. However, it seems like the L/P case would be pretty rare in practice.

| ) | [inline, static] |
Computes the intersects predicate between a PreparedLineString and a Geometry.
| prep | the prepared linestring | |
| geom | a test geometry |
| bool geos::geom::prep::PreparedLineStringIntersects::intersects | ( | const geom::Geometry * | g | ) | const |
Tests whether this geometry intersects a given geometry.
| geom | the test geometry |
