Detailed Description
Note: You cannot declare or create a component of this type in QML code.
Use the parts property on Multipart 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.
Property Documentation
[read-only] empty : bool |
Returns whether the ImmutablePartCollection contains any parts (read-only).
[read-only] size : int |
Returns the number of parts the ImmutablePartCollection contains (read-only).
[read-only] spatialReference : SpatialReference |
Returns the spatial reference of the ImmutablePartCollection (read-only).
Method Documentation
int indexOf(ImmutablePart part) |
Gets the index of part.
Returns the index or -1 if not found.
ImmutablePart part(int index) |
Gets the Part at index.
Returns the ImmutablePart or null if the index isn't valid.
