ClassDescriptionAn abstract implementation for CalcResults.Aggregate functions defined for use with the GeoTools library.Calculates the AverageCalculates the extents (envelope) of the features it visits.Encapsulates the results from a FeatureCalc, and includes methods for obtaining and merging results.Determines the number of features in the collectionObtains the data needed for a Equal Area operation (classification of features into classes each roughly having the same area).Extension of FeatureVisitor for visitors that require access to properties of the feature collection being visited.A visitor which performs a calculation on a FeatureCollection.Group features by one or several attributes and applies an aggregator visitor to each group.Helper class that should be used by optimizations to set the results.This class implements the feature calculation result of the group by visitor.Helper class to help building a valid group by visitor.Gather up all FeatureId strings into a provided HashSet.Quick check to see if an ID filter is found.A visitor that can limit the features that can be visited (for example to implement startOffset, maxFeatures pagination).Calculates the maximum value of an attribute.Calculates the median of an attribute in all features of a collectionCalculates the minimum value of an attribute.Finds the nearest value to the provided one in the attribute domain.Obtains the data needed for a Quantile operation (classification of features into classes of equal size).Determines the standard deviation.Calculates the Sum of Areas for geometric fieldsCalculates the Sum of an attribute (of a FeatureVisitor)Determines the number of unique features in the collection on the basis of the specified feature attribute.Generates a list of unique values from a collection
