MultiPoint(Point[])

Constructs a MultiPoint.

Declaration
public MultiPoint(Point[] points)
Parameters
Type Name Description
Point[] points

The Points for this MultiPoint , or null or an empty array to create the empty point. Elements may be empty Points, but not nulls.
Remarks

For create this Geometry is used a standard GeometryFactory with PrecisionModel == Floating.

MultiPoint(Point[], GeometryFactory)

Constructs a MultiPoint.

Declaration
public MultiPoint(Point[] points, GeometryFactory factory)
Parameters
Type Name Description
Point[] points

The Points for this MultiPoint , or null or an empty array to create the empty point. Elements may be empty Points, but not nulls.

IsValid

Tests whether this Geometry is topologically valid, according to the OGC SFS specification.

For validity rules see the documentation for the specific geometry subclass.
Declaration
public override bool IsValid { get; }
Property Value
Type Description
bool

true if this Geometry is valid.

SortIndex

Gets a value to sort the geometry

Declaration
protected override Geometry.SortIndexValue SortIndex { get; }
Property Value
Type Description
Geometry.SortIndexValue

HasDimension(Dimension)

Tests whether an atomic geometry or any element of a collection has the specified dimension.
In particular, this can be used with mixed-dimension GeometryCollections to test if they contain an element of the specified dimension.

Declaration
public override bool HasDimension(Dimension dim)
Parameters
Type Name Description
Dimension dim

The dimension to test
Returns
Type Description
bool

true if the geometry has or contains an element with the dimension
