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.

Overrides:

getDimension in class GeometryCollection

Returns:

the dimension of the class implementing this interface, whether or not this object is the empty 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 java.lang.String getGeometryType()

Description copied from class: Geometry

Returns the name of this object's com.vivid.jts.geom interface.

Overrides:

getGeometryType in class GeometryCollection

Returns:

the name of this Geometrys most specific com.vividsolutions.jts.geom interface

isClosed

public boolean isClosed()

isSimple

public boolean isSimple()

Description copied from class: Geometry

Tests whether this Geometry is simple. In general, the SFS specification of simplicity follows the rule:

• A Geometry is simple iff the only self-intersections are at boundary points.

Simplicity is defined for each Geometry subclass as follows:

• Valid polygonal geometries are simple by definition, so isSimple trivially returns true.
• Linear geometries are simple iff they do not self-intersect at points other than boundary points.
• Zero-dimensional geometries (points) are simple iff they have no repeated points.
• Empty Geometrys are always simple

  Overrides:

  isSimple in class GeometryCollection

  Returns:

  true if this Geometry has any points of self-tangency, self-intersection or other anomalous points

  See Also:

  Geometry.isValid()

getBoundary

public Geometry getBoundary()

Description copied from class: Geometry

Returns the boundary, or the empty geometry 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."

Overrides:

getBoundary in class GeometryCollection

Returns:

the closure of the combinatorial boundary of this Geometry

reverse

public MultiLineString 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.

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

If this and the other Geometrys are composites and any children are not Geometrys, returns false.

Overrides:

equalsExact in class GeometryCollection

Parameters:

other - the Geometry with which to compare this Geometry

Returns:

true if this and the other Geometry are of the same class and have equal internal data.
