Method Detail

getBounds2D

public abstract java.awt.geom.Rectangle2D getBounds2D()

Description copied from interface: GisFeature

Get the bounding box for this feature.

Specified by:

getBounds2D in interface GisFeature

Returns:

rectangle bounding this feature

getNumPoints

public abstract int getNumPoints()

Description copied from interface: GisFeature

Get total number of points in all parts of this feature.

Specified by:

getNumPoints in interface GisFeature

Returns:

total number of points in all parts of this feature.

getNumParts

public abstract int getNumParts()

Description copied from interface: GisFeature

Get number of parts comprising this feature.

Specified by:

getNumParts in interface GisFeature

Returns:

number of parts comprising this feature.

getGisParts

public abstract java.util.Iterator getGisParts()

Description copied from interface: GisFeature

Get the parts of this feature, in the form of an iterator.

Specified by:

getGisParts in interface GisFeature

Returns:

the iterator over the parts of this feature. Each part is a GisPart.

getShape

public java.awt.Shape getShape()

Convert this GisFeature to a java.awt.Shape, using the default coordinate system, mapping gisFeature(x,y) -> screen(x,y). LOOK STILL HAVE TO crossSeam()

Returns:

shape corresponding to this feature.

getProjectedShape

public java.awt.Shape getProjectedShape(ProjectionImpl displayProject)

Convert this GisFeature to a java.awt.Shape. The data coordinate system is assumed to be (lat, lon), use the projection to transform points, so project.latLonToProj(gisFeature(x,y)) -> screen(x,y).

Parameters:

displayProject - Projection to use to display

Returns:

shape corresponding to this feature

getProjectedShape

public java.awt.Shape getProjectedShape(ProjectionImpl dataProject,
                                        ProjectionImpl displayProject)

Convert this GisFeature to a java.awt.Shape. The data coordinate system is in the coordinates of dataProject, and the screen is in the coordinates of displayProject. So: displayProject.latLonToProj( dataProject.projToLatLon(gisFeature(x,y))) -> screen(x,y).

Parameters:

dataProject - data Projection to use.

displayProject - display Projection to use.

Returns:

shape corresponding to this feature
