## Public Member Functions | |

virtual SphericalRegionType | getType () const |

virtual OctahedronPolygon | getOctahedronPolygon () const |

Return the octahedron contour representation of the polygon. | |

virtual double | getArea () const |

Return the area of the region in steradians. | |

virtual bool | isEmpty () const |

Return true if the region is empty. | |

virtual Vec3d | getPointInside () const |

Return a point located inside the region. | |

virtual SphericalCap | getBoundingCap () const |

Return a bounding SphericalCap. | |

virtual QVariantList | toQVariant () const |

Serialize the region into a QVariant map matching the JSON format. | |

virtual void | serialize (QDataStream &) const |

## Static Public Attributes | |

static const SphericalRegionP | staticInstance |

Definition at line 729 of file StelSphereGeometry.hpp.

virtual double EmptySphericalRegion::getArea | ( | ) | const` [inline, virtual]` |

Return the area of the region in steradians.

Reimplemented from SphericalRegion.

Definition at line 747 of file StelSphereGeometry.hpp.

virtual SphericalCap EmptySphericalRegion::getBoundingCap | ( | ) | const` [inline, virtual]` |

Return a bounding SphericalCap.

This method is heavily used and therefore needs to be very fast. The returned SphericalCap doesn't have to be the smallest one, but smaller is better.

Reimplemented from SphericalRegion.

Definition at line 750 of file StelSphereGeometry.hpp.

virtual OctahedronPolygon EmptySphericalRegion::getOctahedronPolygon | ( | ) | const` [inline, virtual]` |

Return the octahedron contour representation of the polygon.

It can be used for safe computation of intersection/union in the general case.

Implements SphericalRegion.

Definition at line 743 of file StelSphereGeometry.hpp.

virtual Vec3d EmptySphericalRegion::getPointInside | ( | ) | const` [inline, virtual]` |

Return a point located inside the region.

Reimplemented from SphericalRegion.

Definition at line 749 of file StelSphereGeometry.hpp.

virtual bool EmptySphericalRegion::isEmpty | ( | ) | const` [inline, virtual]` |

Return true if the region is empty.

Reimplemented from SphericalRegion.

Definition at line 748 of file StelSphereGeometry.hpp.

virtual void EmptySphericalRegion::serialize | ( | QDataStream & | out |
) | const` [inline, virtual]` |

Serialize the region. This method must allow as fast as possible serialization and work with deserialize().

Implements SphericalRegion.

Definition at line 754 of file StelSphereGeometry.hpp.

virtual QVariantList EmptySphericalRegion::toQVariant | ( | ) | const` [virtual]` |

Serialize the region into a QVariant map matching the JSON format.

The format is ["EMPTY"]

Implements SphericalRegion.
