Detailed Description
Points can be added to, inserted into, and removed from the collection in order to define or change the shape of the Multipoint.
The spatial reference of any Points added to a PointCollection must match that of this PointCollection, or be unspecified (in which case the Points are assumed to have the same spatial reference as this PointCollection).
Relevant samples:
- Create geometries: Create simple geometry types.
- Densify and generalize: A multipart geometry can be densified by adding interpolated points at regular intervals.
Member Function Documentation
[explicit] PointCollection::PointCollection (const Esri::ArcGISRuntime::SpatialReference &spatialReference , QObject *parent = nullptr)
Constructor that takes a SpatialReference spatialReference and an optional parent.
[override virtual] PointCollection::~PointCollection ()
Destructor.
int PointCollection::addPoint (const Esri::ArcGISRuntime::Point &point)
Adds point to the collection.
Returns -1 on error.
int PointCollection::addPoint (double x, double y)
Adds a new point with the given x and y coordinates.
Returns the index of the added point, or -1 on error.
The coordinates must be in the spatial reference of this PointCollection.
int PointCollection::addPoint (double x, double y, double z)
Adds a new point to the collection with the given x, y, and z coordinates.
Returns the index of the added point, or -1 on error.
Note: the coordinates must be in the spatial reference of this PointCollection.
[since Esri::ArcGISRuntime 100.1] void PointCollection::addPoints (const QList<Esri::ArcGISRuntime::Point > &points)
Adds list of points to the collection.
This function was introduced in Esri::ArcGISRuntime 100.1.
void PointCollection::addPoints (Esri::ArcGISRuntime::PointCollection *points)
Adds the points in this PointCollection points to this collection.
void PointCollection::addPoints (const Esri::ArcGISRuntime::ImmutablePointCollection &points)
Adds the points in the ImmutablePointCollection points to this collection.
int PointCollection::indexOf (const Esri::ArcGISRuntime::Point &point) const
Gets the index of point in the collection.
Returns -1 if the point is not found.
void PointCollection::insertPoint (int pointIndex , const Esri::ArcGISRuntime::Point &point)
Inserts a point into this PointCollection at pointIndex.
void PointCollection::insertPoint (int pointIndex , double x, double y)
Inserts a point with the given x and y coordinates into this PointCollection at pointIndex.
The coordinates must be in the spatial reference of this PointCollection.
void PointCollection::insertPoint (int pointIndex , double x, double y, double z)
Inserts a point with the given x, y, and z coordinates into this PointCollection at pointIndex.
The coordinates must be in the spatial reference of this PointCollection.
bool PointCollection::isEmpty () const
Gets whether this PointCollection contains any points.
Returns true if this PointCollection contains points.
Esri::ArcGISRuntime::Point PointCollection::point(int index) const
Gets the point at index.
Returns an empty Point object on error.
See also setPoint().
void PointCollection::removeAll ()
Removes all the points from this PointCollection.
void PointCollection::removePoint (int pointIndex )
Removes the point at pointIndex.
void PointCollection::setPoint (int pointIndex , const Esri::ArcGISRuntime::Point &point)
Reassigns the point at pointIndex to point.
See also point().
[override virtual] int PointCollection::size() const
Gets the number of points in this PointCollection.
Esri::ArcGISRuntime::SpatialReference PointCollection::spatialReference () const
Gets the SpatialReference of this PointCollection.
