BDPGeometry
@protocol BDPGeometry <BDPDeepCopy>
@brief Geometrical methods required for implementation of a concrete geometry class. @copyright Bluedot Innovation
-
Sometimes referred to as ‘hit test’ or ‘Point in polygon test’, this method determines whether the given @ref BDPoint “point” falls on, or inside the bounds of this geometry.
@returns YES if the point falls on or inside the bounds, NO if the point falls outside the bounds
Declaration
Objective-C
- (BOOL)intersects:(BDGeometry *)geometry;
-
Currently, only Circles may receive this message; other shapes will throw an assertion error in DEBUG or return NO in RELEASE.
@returns YES if this shape fully encloses the specified shape, NO otherwise.Declaration
Objective-C
- (BOOL)isEnclosedBy:(BDGeometry *)geometry;
-
Calculates the minimum @ref BDBoundingBox “bounding-box” that encloses this geometry.
Notably, for @ref BDBoundingBox instances, this will simply return a `self` reference.
For @ref BDPoint instances, this will return a zero-sized box positioned at the point.
@returns the minimum @ref BDBoundingBox “bounding-box” that encloses this geometry.
Declaration
Objective-C
- (BDBoundingBox *)boundingBox;
-
@returns The centre of a geometrical shape.
Declaration
Objective-C
- (BDPoint *)centroid;
-
@returns the distance to another geometric shape.
Declaration
Objective-C
- (BDLocationDistance)distanceTo:(BDGeometry *)geometry;
-
@returns The type of current geometry. Available values: point, circle, lineString, boundingBox, polygon.
Declaration
Objective-C
- (BDGeometryType)geometryType;
