Member Function Documentation

bool geos::geom::prep::PreparedPolygonPredicate::isAllTestComponentsInTarget ( const geom::Geometry testGeom) const
protected

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

Handles both linear and point components.

Parameters
geoma geometry to test
Returns
true if all components of the argument are contained in the target geometry
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
geoma geometry to test
Returns
true if all componenta of the argument are contained in the target geometry interior
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
geomthe test geometry
repPtsthe representative points of the target geometry
Returns
true if any component intersects the areal test geometry
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
geoma geometry to test
Returns
true if any component of the argument intersects the prepared geometry
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
geoma geometry to test
Returns
true if any component of the argument intersects the prepared area geometry interior
