Member Function Documentation

static bool geos::geom::prep::PreparedLineStringIntersects::intersects ( PreparedLineString prep,
const geom::Geometry geom 
)
inlinestatic

Computes the intersects predicate between a PreparedLineString and a Geometry.

Parameters
prepthe prepared linestring
geoma test geometry
Returns
true if the linestring intersects the geometry

References intersects().

bool geos::geom::prep::PreparedLineStringIntersects::intersects ( const geom::Geometry g) const

Tests whether this geometry intersects a given geometry.

Parameters
geomthe test geometry
Returns
true if the test geometry intersects
bool geos::geom::prep::PreparedLineStringIntersects::isAnyTestPointInTarget ( const geom::Geometry testGeom) const
protected

Tests whether any representative point of the test Geometry intersects the target geometry. Only handles test geometries which are Puntal (dimension 0)

Parameters
geoma Puntal geometry to test
Returns
true if any point of the argument intersects the prepared geometry
