Detailed Description
Polygons and polyline can have multiple disjoint parts. Each part is represented by an ImmutablePart. A part is composed of segments representing the edge of the polygon or polyline.
Use the ImmutablePartCollection returned from the Multipart getParts method to iterate through all of the parts in a Multipart.
Because geometries themselves are immutable, the collections they are composed of are also immutable. For geometry editing or creation workflows, a mutable PartCollection is used instead. PartCollection has constructors that take an ImmutablePartCollection, allowing creation of new geometries from parts of existing ones.
Member Function Documentation
ImmutablePartCollection::ImmutablePartCollection ()
Default constructor.
ImmutablePartCollection::ImmutablePartCollection (const Esri::ArcGISRuntime::ImmutablePartCollection &other)
Copy constructor from other ImmutablePartCollection.
[noexcept] ImmutablePartCollection::ImmutablePartCollection (Esri::ArcGISRuntime::ImmutablePartCollection &&other)
Move constructor from other ImmutablePartCollection.
[override virtual noexcept] ImmutablePartCollection::~ImmutablePartCollection ()
Destructor.
int ImmutablePartCollection::indexOf (const Esri::ArcGISRuntime::ImmutablePart &part) const
Retrieves the position of the given part in the immutable part collection.
- part - The part you want to find.
bool ImmutablePartCollection::isEmpty () const
Returns true if the immutable part collection contains no parts.
Esri::ArcGISRuntime::ImmutablePart ImmutablePartCollection::part(int index) const
Returns a part at the specified index in the immutable part collection.
A part is represented by an immutable collection of segments.
- index - Position to retrieve the part.
[override virtual] int ImmutablePartCollection::size() const
Returns the number of parts in the immutable part collection.
Esri::ArcGISRuntime::SpatialReference ImmutablePartCollection::spatialReference () const
Returns the spatial reference for the immutable part collection.
If the collection does not have a spatial reference, empty is returned.
[noexcept] Esri::ArcGISRuntime::ImmutablePartCollection &ImmutablePartCollection::operator=(Esri::ArcGISRuntime::ImmutablePartCollection &&other)
Move operator from other ImmutablePartCollection.
Esri::ArcGISRuntime::ImmutablePartCollection &ImmutablePartCollection::operator=(const Esri::ArcGISRuntime::ImmutablePartCollection &other)
Assignment operator from other ImmutablePartCollection.
