      DefaultGridFeatureBuilder

public final class DefaultGridFeatureBuilder
extends GridFeatureBuilder

A basic implementation of GridFeatureBuilder which will create a SimpleFeatureType having two properties:

• element - TYPE Polygon
• id - TYPE Integer

The attribute names can also be referred to using GridFeatureBuilder.DEFAULT_GEOMETRY_ATTRIBUTE_NAME and ID_ATTRIBUTE_NAME

Grid elements will be assigned sequential id values starting with 1.
