p_prepPoly

the PreparedPolygon to evaluate

Member Function Documentation

getOutermostTestComponentLocation()

geom::Location geos::geom::prep::PreparedPolygonPredicate::getOutermostTestComponentLocation ( const geom::Geometry *  testGeom ) const

protected

Returns the outermost Location among a test point from each components of the test geometry.

Parameters

testGeom

a geometry to test

Returns

the outermost Location

isAllTestComponentsInTargetInterior()

bool geos::geom::prep::PreparedPolygonPredicate::isAllTestComponentsInTargetInterior ( const geom::Geometry *  testGeom ) const

protected

Tests whether all components of the test Geometry are contained in the interior of the target geometry.

Handles both linear and point components.

Parameters

testGeom

a geometry to test

Returns

true if all componenta of the argument are contained in the target geometry interior

isAnyTargetComponentInAreaTest()

bool geos::geom::prep::PreparedPolygonPredicate::isAnyTargetComponentInAreaTest ( const geom::Geometry *  testGeom, const geom::Coordinate::ConstVect *  targetRepPts  ) const

protected

Tests whether any component of the target geometry intersects the test geometry (which must be an areal geometry)

Parameters

testGeom	the test geometry
targetRepPts	the representative points of the target geometry

Returns

true if any component intersects the areal test geometry

isAnyTestComponentInTarget()

bool geos::geom::prep::PreparedPolygonPredicate::isAnyTestComponentInTarget ( const geom::Geometry *  testGeom ) const

protected

Tests whether any component of the test Geometry intersects the area of the target geometry.

Handles test geometries with both linear and point components.

Parameters

testGeom

a geometry to test

Returns

true if any component of the argument intersects the prepared geometry

isAnyTestComponentInTargetInterior()

bool geos::geom::prep::PreparedPolygonPredicate::isAnyTestComponentInTargetInterior ( const geom::Geometry *  testGeom ) const

protected

Tests whether any component of the test Geometry intersects the interior of the target geometry.

Handles test geometries with both linear and point components.

Parameters

testGeom

a geometry to test

Returns

true if any component of the argument intersects the prepared area geometry interior
