Method Detail

createClockwiseTriangle

public static Triangle createClockwiseTriangle(Point c0,
                               Point c1,
                               Point c2)

equals

public boolean equals(Triangle triangle)

getAxisCount

public int getAxisCount()

Specified by:

getAxisCount in interface Geometry

Overrides:

getAxisCount in class AbstractGeometry

getCircumcircle

public Circle getCircumcircle()

Computes the circumcircle of a triangle. The circumcircle is the smallest circle which encloses the triangle.

Returns:

The circumcircle of the triangle.

getCoordinate

public double getCoordinate(int index,
                   int axisIndex)

getCoordinates

public double[] getCoordinates()

Specified by:

getCoordinates in interface LineString

Specified by:

getCoordinates in class AbstractLineString

getEnvelopeInternal

public BoundingBoxDoubleGf getEnvelopeInternal()

Get the envelope of the Triangle.

Returns:

The envelope.

getInCentre

public Point getInCentre()

getP0

public Point getP0()

getP1

public Point getP1()

getP2

public Point getP2()

getPolygon

public Polygon getPolygon(GeometryFactory geometryFactory)

getVertexCount

public int getVertexCount()

Description copied from interface: Geometry

Returns the count of this Geometrys vertices. The Geometry s contained by composite Geometrys must be Geometry's; that is, they must implement getNumPoints

Returns:

the number of vertices in this Geometry

hasVertex

public boolean hasVertex(Point coordinate)

Returns true if the coordinate lies inside or on the edge of the Triangle.

Specified by:

hasVertex in interface LineString

Overrides:

hasVertex in class AbstractLineString

Parameters:

coordinate - The coordinate.

Returns:

True if the coordinate lies inside or on the edge of the Triangle.

intersection

public LineSegment intersection(GeometryFactory geometryFactory,
                       LineSegment line)

intersectsCircumCircle

public boolean intersectsCircumCircle(Point point)

isEmpty

public boolean isEmpty()

Description copied from class: AbstractGeometry

Tests whether the set of points covered by this Geometry is empty.

Specified by:

isEmpty in interface Geometry

Specified by:

isEmpty in class AbstractGeometry

Returns:

true if this Geometry does not cover any points

toString

public String toString()

Overrides:

toString in class AbstractGeometry
