A builder to construct or modify multipoint geometries.
Instances of this class represent a builder that can build multipoint geometries. Multipoint geometries are immutable, they cannot be modified after they are created. Use builders to create new geometries either from scratch, or by using an existing geometry as a starting off point. Modifications made through the builder affect only its own internal copy of the geometry. They do not affect the original geometry.

Factory method to create a geometry builder from a geometry type and spatial reference.
Prior to v100.12, only geometries without curves could be used. Passing in a geometry where AGSGeometry::hasCurves
is YES
would fail to replace the geometry.
From v100.12, geometries with curves are supported.
geometryType | The type of geometry to be constructed. |
sr | The spatial reference for the geometry to be constructed. |
AGSGeometryBuilder::hasCurves
- (instancetype) initWithMultipoint: | (nullable AGSMultipoint *) | multipoint |
Initializes a multipoint builder.
multipoint | The geometry to be used as the starting point for further modifications. Can be nil. |
- (instancetype) initWithPoints: | (NSArray< AGSPoint * > *) | points |
Initializes a multipoint builder.
points | for the geometry to be constructed |
- (instancetype) initWithSpatialReference: | (nullable AGSSpatialReference *) | sr |
Initializes a builder.
sr | The spatial reference for the geometry to be constructed |
- (BOOL) isEmpty |
Indicates whether the builder's geometry is empty.
AGSGeometry::isEmpty
+ (instancetype) multipointBuilderWithMultipoint: | (nullable AGSMultipoint *) | multipoint |
Initializes a multipoint builder.
multipoint | The geometry to be used as the starting point for further modifications. Can be nil. |
+ (instancetype) multipointBuilderWithPoints: | (NSArray< AGSPoint * > *) | points |
Initializes a multipoint builder.

+ (instancetype) multipointBuilderWithSpatialReference: | (nullable AGSSpatialReference *) | sr |
Initializes a builder.
sr | The spatial reference for the geometry to be constructed |
- (instancetype) replaceGeometry: | (nullable AGSGeometry *) | geometry |
Replaces the builder's geometry with the provided one.
This does not update the spatial reference of the builder. If the geometry is nil
, the builder is cleared.
Prior to v100.12, only geometries without curves could be used. Passing in a geometry where AGSGeometry::hasCurves
is YES
would fail to replace the geometry.
From v100.12, geometries with curves are supported.
geometry | The geometry object to replace with. |
- (instancetype) replaceGeometry: | (nullable AGSMultipoint *) | geometry |
Replaces the builder's geometry with the provided one.
geometry | to replace with |
- (AGSMultipoint *) toGeometry |
Returns the multipoint geometry this builder is constructing or modifying.
Implements AGSGeometryBuilder.
|
readnonatomicstronginherited |
Smallest, rectangular bounding-box that covers the builder's geometry.
AGSGeometry::extent
|
readnonatomicassigninherited |
The type of geometry the builder will construct or modify.
|
readnonatomicassigninherited |
A value indicating whether the geometry builder currently contains any curve segments.
The ArcGIS Platform supports polygon and polyline geometries that contain curve segments (where AGSSegment::curve
is YES
, sometimes known as true curves or nonlinear segments). Curves may be present in certain types of data - for example Mobile Map Packages (MMPKs), or geometry JSON.
Prior to v100.12, only AGSLineSegment
instances were supported when creating new geometries using an AGSMultipartBuilder
. Attempting to add curve geometries to an AGSMultipartBuilder
would cause an error.
From v100.12, you can use curves in an AGSMultipartBuilder
. New segment types AGSCubicBezierSegment
and AGSEllipticArcSegment
represent different types of curve that can be added to polygon and polyline geometries.
|
readnonatomicassigninherited |
Indicates whether the builder's geometry contains m (measure) values.
AGSGeometry::hasM
|
readnonatomicassigninherited |
Indicates whether the builder's geometry contains z coordinate values.
AGSGeometry::hasZ
|
readwritenonatomicstrong |
The points that make up this multipoint.
|
readnonatomicstronginherited |
The spatial reference associated with the builder's gometry. It specifies the coordinate system for the geometry's x, y, and z coordinate values.
