Member Function Documentation

intersects() [1/2]

bool geos::geom::prep::PreparedLineStringIntersects::intersects

(

const geom::Geometry *

g

)

const

Tests whether this geometry intersects a given geometry.

Parameters

g	the test geometry

Returns

true if the test geometry intersects

intersects() [2/2]

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

prep	the prepared linestring
geom	a test geometry

Returns

true if the linestring intersects the geometry

isAnyTestPointInTarget()

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

testGeom

a Puntal geometry to test

Returns

true if any point of the argument intersects the prepared geometry
