Class Summary

Class	Description
CategorizeFunction	Implementation of "Categorize" as a normal function.
ClassificationFunction	Parent for classifiers which break a feature collection into the specified number of classes.
Classifier	The data structure returned by classification functions.
ClassifyFunction
Collection_AverageFunction	Calculates the average value of an attribute for a given FeatureCollection and Expression.
Collection_BoundsFunction	Calculates the bounds of an attribute for a given FeatureCollection and Expression.
Collection_CountFunction	Calculates the count value of an attribute for a given SimpleFeatureCollection and Expression.
Collection_MaxFunction	Calculates the maximum value of an attribute for a given FeatureCollection and Expression.
Collection_MedianFunction	Calculates the median value of an attribute for a given FeatureCollection and Expression.
Collection_MinFunction	Calculates the minimum value of an attribute for a given FeatureCollection and Expression.
Collection_NearestFunction	Finds the nearest value to the provided one in the attribute domain.
