MultiLineString(LineString[])

Constructs a MultiLineString.

Declaration
public MultiLineString(LineString[] lineStrings)
Parameters
Type Name Description
LineString[] lineStrings

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

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

MultiLineString(LineString[], GeometryFactory)

Constructs a MultiLineString.

Declaration
public MultiLineString(LineString[] lineStrings, GeometryFactory factory)
Parameters
Type Name Description
LineString[] lineStrings

The LineStrings for this MultiLineString, or null or an empty array to create the empty point. Elements may be empty LineStrings, but not nulls.
GeometryFactory factory

Boundary

Returns the boundary, or an empty geometry of appropriate dimension if this Geometry is empty. For a discussion of this function, see the OpenGIS Simple Features Specification. As stated in SFS Section 2.1.13.1, "the boundary of a Geometry is a set of Geometries of the next lower dimension."

Declaration
public override Geometry Boundary { get; }
Property Value
Type Description
Geometry

The closure of the combinatorial boundary of this Geometry.

IsClosed

Gets a value indicating whether this instance is closed.

Declaration
public bool IsClosed { get; }
Property Value
Type Description
bool

true if this instance is closed; otherwise, false.

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

Remarks

NOTE:
For JTS v1.17 this property's getter has been renamed to getTypeCode(). In order not to break binary compatibility we did not follow.

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
