                                                                                String[] columnames,

                                                                                boolean useMultiPoint)

Creates a point feature from a array of objects. The Objects on index xIndex and yIndex are used to create a point.

Parameters:

attributes - The attributes of the Feature.

columnames - The columnames corresponding the attribute names in the FeatureSchema. It gives the order of adding attributes to the Feature. If columnames is null the attributes are added in that order. Not recommended example: the columname at index 0 is used to look up the index (n) of the attribute where attributename equals the columnname at index 0 then that index (n) is used to at the attribute to the feature. So in this example the attribute at index 0 is added to the feature at index n.

xIndex - The index in the object array that is used as x coord for creating the point

yIndex - The index in the object array that is used as y coord for creating the point

fs - The feature schema that is needed to create a feature

xyAsAttribute - If true the x and y coords are also stored as attribute.

useMultiPoint - If true create a MultiPoint for the coordinates

createPointFeature

                                                                                String[] columnames,
                                                                                double x,
                                                                                double y,
                                                                                org.locationtech.jts.jump.feature.FeatureSchema fs,
                                                                                boolean useMultiPoint)

Creates a point feature from a array of objects. The x and y are used for creating the point.

Parameters:

attributes - The attributes of the Feature.

columnames - The columnames corresponding the attribute names in the FeatureSchema. It gives the order of adding attributes to the Feature. If columnames is null the attributes are added in that order. Not recommended example: the columname at index 0 is used to look up the index (n) of the attribute where attributename equals the columnname at index 0 then that index (n) is used to at the attribute to the feature. So in this example the attribute at index 0 is added to the feature at index n.

x - the x coord used for creating the point

y - the y coord used for creating the point

fs - The feature schema that is needed to create a feature

useMultiPoint - If true create a MultiPoint for the coordinates
