Constructor Detail

MultiLineString

public MultiLineString(LineString[] lineStrings,
               PrecisionModel precisionModel,
               int SRID)

Deprecated. Use GeometryFactory instead

Constructs a MultiLineString.

Parameters:

lineStrings - the LineStrings for this MultiLineString , or null or an empty array to create the empty geometry. Elements may be empty LineStrings, but not null s.

precisionModel - the specification of the grid of allowable points for this MultiLineString

SRID - the ID of the Spatial Reference System used by this MultiLineString

MultiLineString

public MultiLineString(LineString[] lineStrings,
               GeometryFactory factory)

Parameters:

lineStrings - the LineStrings for this MultiLineString, or null or an empty array to create the empty geometry. Elements may be empty LineStrings, but not nulls.

Method Detail

getDimension

public int getDimension()

Description copied from class: Geometry

Returns the dimension of this geometry. The dimension of a geometry is is the topological dimension of its embedding in the 2-D Euclidean plane. In the JTS spatial model, dimension values are in the set {0,1,2}.

Note that this is a different concept to the dimension of the vertex Coordinates. The geometry dimension can never be greater than the coordinate dimension. For example, a 0-dimensional geometry (e.g. a Point) may have a coordinate dimension of 3 (X,Y,Z).

Overrides:

getDimension in class GeometryCollection

Returns:

the topological dimension of this geometry.

getBoundaryDimension

public int getBoundaryDimension()

Description copied from class: Geometry

Returns the dimension of this Geometrys inherent boundary.

Overrides:

getBoundaryDimension in class GeometryCollection

Returns:

the dimension of the boundary of the class implementing this interface, whether or not this object is the empty geometry. Returns Dimension.FALSE if the boundary is the empty geometry.

getGeometryType

public String getGeometryType()

Description copied from class: Geometry

Returns the name of this Geometry's actual class.

Overrides:

getGeometryType in class GeometryCollection

Returns:

the name of this Geometrys actual class

isClosed

public boolean isClosed()

getBoundary

public Geometry getBoundary()

Gets the boundary of this geometry. The boundary of a lineal geometry is always a zero-dimensional geometry (which may be empty).

Overrides:

getBoundary in class GeometryCollection

Returns:

the boundary geometry

See Also:

Geometry.getBoundary()

reverse

public Geometry reverse()

Creates a MultiLineString in the reverse order to this object. Both the order of the component LineStrings and the order of their coordinate sequences are reversed.

Overrides:

reverse in class GeometryCollection

Returns:

a MultiLineString in the reverse order

equalsExact

public boolean equalsExact(Geometry other,
                  double tolerance)

Description copied from class: Geometry

Returns true if the two Geometrys are exactly equal, up to a specified distance tolerance. Two Geometries are exactly equal within a distance tolerance if and only if:

• they have the same structure
• they have the same values for their vertices, within the given tolerance distance, in exactly the same order.

This method does not test the values of the GeometryFactory, the SRID, or the userData fields.

To properly test equality between different geometries, it is usually necessary to Geometry.normalize() them first.

Overrides:

equalsExact in class GeometryCollection

Parameters:

other - the Geometry with which to compare this Geometry

tolerance - distance at or below which two Coordinates are considered equal

Returns:

true if this and the other Geometry have identical structure and point values, up to the distance tolerance.
