Method Detail

getPoints

public GeoArray getPoints()

Description copied from interface: GeoPath

Return the points that make up the path as an array of Geo object. Closed paths are not specially marked. Specifically, closed paths do not have equal first and last Geo points in the returned array.

Specified by:

getPoints in interface GeoPath

Returns:

the Geo points of the Path

generate

public boolean generate(Projection proj)

Description copied from class: OMGraphicAdapter

Prepare the graphic for rendering. This must be done before calling render()! If a vector graphic has lat-lon components, then we project these vertices into x-y space. For raster graphics we prepare in a different fashion.

If the generate is unsuccessful, it's usually because of some oversight, (for instance if proj is null), and if debugging is enabled, a message may be output to the controlling terminal.

Specified by:

generate in interface OMGeometry

Specified by:

generate in class OMGraphicAdapter

Parameters:

proj - Projection

Returns:

boolean true if successful, false if not.

See Also:

OMGraphicAdapter.regenerate(com.bbn.openmap.proj.Projection)

isGeometryClosed

protected boolean isGeometryClosed(float[] rawllpts)

isSegmentNear

public boolean isSegmentNear(GeoSegment s,
                             double epsilon)

Description copied from interface: GeoPath

Does the segment s come within epsilon (in radians) of us?

Specified by:

isSegmentNear in interface GeoPath

length

public int length()

Specified by:

length in interface GeoPath

Returns:

the number of points in the path.

pointIterator

public GeoPath.PointIterator pointIterator()

Specified by:

pointIterator in interface GeoPath

Returns:

an iterator over the points of the path *

segmentIterator

public GeoPath.SegmentIterator segmentIterator()

Specified by:

segmentIterator in interface GeoPath

Returns:

an iterator over the segments of the path *
