Detailed Description

Computes the intersects spatial relationship predicate for a target PreparedLineString relative to all other Geometry classes.

Uses short-circuit tests and indexing to improve performance.

Member Function Documentation

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

Tests whether this geometry intersects a given geometry. Parameters: geom  the test geometry Returns: true if the test geometry intersects

static bool geos::geom::prep::PreparedLineStringIntersects::intersects (  PreparedLineString &  prep, const geom::Geometry *  geom )  [inline, static]

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

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: geom  a Puntal geometry to test Returns: true if any point of the argument intersects the prepared geometry
