Detailed Description

GeoDataRegion describes the visibility and extent of a feature.

GeoDataRegion is a tool class that implements the Region tag/class of the Open Geospatial Consortium standard KML 2.2.

GeoDataRegion provides all aspects that can be taken into account to find out whether a GeoDataFeature (or a GeoDataLink) is visible on the map:

• On one hand GeoDataRegion owns a GeoDataLatLon(Alt)Box object. GeoDataLatLon(Alt)Box is a bounding box in geodesic coordinates. As such GeoDataLatLon(Alt)Box allows to determine whether the feature is located inside the area that the observer/camera is looking at ("viewLatLonAltBox").
• Additionally GeoDataRegion has got a GeoDataLod ("Level of Detail") object. GeoDataLod describes the least and maximum size on the screen that is required to consider a feature to be active.

A feature is visible if it's active and if its latLonAltBox covers the area that is being looked at by the observer.

Constructor & Destructor Documentation

GeoDataRegion() [1/3]

Marble::GeoDataRegion::GeoDataRegion

(

)

Creates a new GeoDataRegion object that is not assigned to a feature. Naturally it's recommended to assign a feature or a link to the region (and therefore it's recommended to use one of the other constructors instead). This constructor allows to create a stand alone region which can get assigned to the feature or link later on.

Definition at line 23 of file GeoDataRegion.cpp.

GeoDataRegion() [2/3]

Marble::GeoDataRegion::GeoDataRegion

(

const GeoDataRegion &

other

)

Creates a new GeoDataRegion as a copy of other.

Definition at line 29 of file GeoDataRegion.cpp.

GeoDataRegion() [3/3]

Marble::GeoDataRegion::GeoDataRegion ( GeoDataFeature * feature )

explicit

Creates a new GeoDataRegion object that is associated to a feature. In the model the feature represents the parent object of the region.

Definition at line 35 of file GeoDataRegion.cpp.

~GeoDataRegion()

Marble::GeoDataRegion::~GeoDataRegion ( )

override

Destroys a Region object.

Definition at line 41 of file GeoDataRegion.cpp.

Member Function Documentation

latLonAltBox()

const GeoDataLatLonAltBox & Marble::GeoDataRegion::latLonAltBox

(

)

const

Returns a geodesic bounding box ("latLonAltBox") of the region. Returns a geodesic bounding box that describes the extent of a feature or a link. If no latLonAltBox has been set then a GeoDataLatLonAltBox object will be calculated automatically: If the associated parent object is a feature then the geometry that might be associated to the feature will be used to calculate the GeoDataLatLonAltBox. Otherwise the coordinate will be used to create a GeoDataLatLonAltBox (in case that there is no geometry assigned to the feature or if the parent object of the region is a GeoDataLink).

Definition at line 61 of file GeoDataRegion.cpp.

lod()

GeoDataLod & Marble::GeoDataRegion::lod

(

)

const

Returns the region's level of detail. The level of detail is returned as a lod object. If no lod has been set then a GeoDataLod object with default values is being returned.

Definition at line 97 of file GeoDataRegion.cpp.

nodeType()

const char * Marble::GeoDataRegion::nodeType ( ) const

overridevirtual

Provides type information for downcasting a GeoNode.

Implements Marble::GeoNode.

Definition at line 46 of file GeoDataRegion.cpp.

operator!=()

bool Marble::GeoDataRegion::operator!=

(

const GeoDataRegion &

other

)

const

Definition at line 56 of file GeoDataRegion.cpp.

operator=()

GeoDataRegion & Marble::GeoDataRegion::operator=

(

const GeoDataRegion &

other

)

Definition at line 130 of file GeoDataRegion.cpp.

operator==()

bool Marble::GeoDataRegion::operator==

(

const GeoDataRegion &

other

)

const

Definition at line 51 of file GeoDataRegion.cpp.

pack()

void Marble::GeoDataRegion::pack ( QDataStream & stream ) const

override

Serialize the Region to a stream.

Parameters

stream

the stream.

Definition at line 114 of file GeoDataRegion.cpp.

setLatLonAltBox()

void Marble::GeoDataRegion::setLatLonAltBox

(

const GeoDataLatLonAltBox &

latLonAltBox

)

Sets the latLonAltBox of the region. Sets the geodesic bounding box that describes the extent of a feature or a link.

Definition at line 91 of file GeoDataRegion.cpp.

setLod()

void Marble::GeoDataRegion::setLod

(

const GeoDataLod &

lod

)

Sets a region's level of detail. The level of detail is set as a lod object.

Definition at line 108 of file GeoDataRegion.cpp.

unpack()

void Marble::GeoDataRegion::unpack ( QDataStream & stream )

override

Unserialize the Region from a stream.

Parameters

stream

the stream.

Definition at line 122 of file GeoDataRegion.cpp.
