Method Detail

createVectorLayer

public static VectorLayerImpl createVectorLayer(FeatureCollection c)

Creates an IVectorLayer from a FeatureCollection.

Parameters:

c - The FeatureCollection must contain simple Features, this means that a Feature has only one geometry and only properties with different names. If a Feature has more geometries, it will be used the first. If a Feature has more properties with the same name, it will be used the first. Some cases can't handled, if the Features contains other Features. A Feature without geometry will be skipped.

Returns:

An IVectorLayer with IFeatures. The IFeatures contains only one Geometry and only properties with different names.

createVectorLayer

public static VectorLayerImpl createVectorLayer(Feature f)

Creates an IVectorLayer from a Feature.

Parameters:

f - The Feature must be simple, this means that a Feature has only one geometry and only properties with different names. If a Feature has more geometries, it will be used the first. If a Feature has more properties with the same name, it will be used the first. A case can't handled, if the Feature contains other Features. If the Feature is a FeatureCollection, it can handled. A Feature without geometry will be skipped.

Returns:

An IVectorLayer with a IFeature. The IFeature contains only one Geometry and only properties with different names.

createVectorLayer

public static VectorLayerImpl createVectorLayer(Geometry g)

Creates an IVectorLayer from a Geometry.

Parameters:

g - If the Geometry isn't simple, it will be linearized.

Returns:

An IVectorLayer with a IFeature. The IFeature contains only one Geometry and no properties.

createFeatureCollection

public static GenericFeatureCollection createFeatureCollection(es.unex.sextante.dataObjects.IVectorLayer l)
                                                        throws es.unex.sextante.exceptions.IteratorException,
                                                               IllegalArgumentException,
                                                               InstantiationException,
                                                               IllegalAccessException

Creates a FeatureCollection from an IVectorLayer.

Parameters:

l - Every IVectorLayer.

Returns:

FeatureCollection

Throws:

es.unex.sextante.exceptions.IteratorException

IllegalArgumentException

InstantiationException

IllegalAccessException

createFeature

public static Feature createFeature(es.unex.sextante.dataObjects.IVectorLayer l)
                             throws es.unex.sextante.exceptions.IteratorException,
                                    IllegalArgumentException,
                                    InstantiationException,
                                    IllegalAccessException

Creates a Feature from an IVectorLayer.

Parameters:

l - IVectorLayer

Returns:

feature

Throws:

es.unex.sextante.exceptions.IteratorException

IllegalArgumentException

InstantiationException

IllegalAccessException

createGeometry

public static Geometry createGeometry(es.unex.sextante.dataObjects.IVectorLayer l)
                               throws es.unex.sextante.exceptions.IteratorException

Creates a Geometry from an IVectorLayer.

Parameters:

l - Every IVectorLayer.

Returns:

Returns a Geometry. If the IVectorLayer contains more than one IFeature, they will be merged to a MultiGeometry.

Throws:

es.unex.sextante.exceptions.IteratorException
