Constructor Detail

GeoPolygon

protected GeoPolygon()

Create an empty geographic polygon. This initializer is available for subclasses which need to compute points. It should be followed by a call to setGeoPoints

GeoPolygon

public GeoPolygon(GeoCoord[] coordinates)

Create a geographic polygon with the specified coordinates

Parameters:

coordinates - the coordinates for the geographic polygon

Method Detail

getCenter

public GeoCoord getCenter()

Get the center of the GeoPolygon

Specified by:

getCenter in interface Locatable

Specified by:

getCenter in interface GeoShape

Returns:

the center of the GeoPolygon

getCoordinates

public java.util.ArrayList<GeoCoord> getCoordinates()

Return the list of coordinates for this GeoPolygon

Returns:

the coordinate list

getData

public DataRecord getData()

Gets the data record associated with this GeoPolygon

Specified by:

getData in interface GeoShape

Returns:

the data record associated with this GeoPolygon

getGeoBounds

public GeoBounds getGeoBounds()

Get the geographic bounds for this shape.

Specified by:

getGeoBounds in interface GeoShape

Returns:

the geographic bounds for this shape

getGeoPoints

public GeoCoord[] getGeoPoints()

Returns the list of Geographic coordinates for this GeoPolygon

Returns:

the list of Geographic coordinates for this GeoPolygon

getRadius

public double getRadius()

Get the radius for this GeoPolygon

Specified by:

getRadius in interface Locatable

Specified by:

getRadius in interface GeoShape

Returns:

the radius, in meters

getRenderStyle

public RenderStyle getRenderStyle()

Get the rendering style for this GeoPolygon.

Specified by:

getRenderStyle in interface GeoShape

Returns:

the Rendering style

project

public void project(Projection proj)

Projects the geographic coordinates into the given projection

Specified by:

project in interface GeoShape

Parameters:

proj - the Projection for the conversion

setData

public void setData(DataRecord rec)

Sets the data record of this GeoPolygon.

Specified by:

setData in interface GeoShape

Parameters:

rec - the data record associated with this GeoPolygon

setGeoPoints

protected void setGeoPoints(GeoCoord[] coordinates)

Set the geographic coordinates for this polygon. Subclasses which need to compute the geographic points may use this method to initialize the coordinates.

Parameters:

coordinates - the coordinates for the geographic polygon

setRenderStyle

public void setRenderStyle(RenderStyle style)

Set the rendering style for this GeoPolygon. Any fields specifically set for a GeoShape should override the layer's default style.

Specified by:

setRenderStyle in interface GeoShape

Parameters:

style - The rendering style
