Interface | Description |
---|---|
CalcResult |
Encapsulates the results from a FeatureCalc, and includes methods for obtaining and merging
results.
|
FeatureAttributeVisitor |
Extension of FeatureVisitor for visitors that require access to properties of the feature
collection being visited.
|
FeatureCalc |
A visitor which performs a calculation on a FeatureCollection.
|
LimitingVisitor |
A visitor that can limit the features that can be visited (for example to implement startOffset,
maxFeatures pagination).
|
SumVisitor.SumStrategy |
Class | Description |
---|---|
AbstractCalcResult |
An abstract implementation for CalcResults.
|
AverageVisitor |
Calculates the Average
|
AverageVisitor.AverageResult | |
BoundsVisitor |
Calculates the extents (envelope) of the features it visits.
|
BoundsVisitor.BoundsResult | |
CalcUtil | |
CollectionUtil | |
CountVisitor |
Determines the number of features in the collection
|
CountVisitor.CountResult | |
EqualAreaListVisitor |
Obtains the data needed for a Equal Area operation (classification of features into classes each
roughly having the same area).
|
GroupByVisitor |
Group features by one or several attributes and applies an aggregator visitor to each group.
|
GroupByVisitor.GroupByRawResult |
Helper class that should be used by optimizations to set the results.
|
GroupByVisitor.GroupByResult |
This class implements the feature calculation result of the group by visitor.
|
GroupByVisitorBuilder |
Helper class to help building a valid group by visitor.
|
IdCollectorFilterVisitor |
Gather up all FeatureId strings into a provided HashSet.
|
IdFinderFilterVisitor |
Quick check to see if an ID filter is found.
|
MaxVisitor |
Calculates the maximum value of an attribute.
|
MaxVisitor.MaxResult | |
MedianVisitor |
Calculates the median of an attribute in all features of a collection
|
MedianVisitor.MedianResult | |
MinVisitor |
Calculates the minimum value of an attribute.
|
MinVisitor.MinResult | |
NearestVisitor |
Finds the nearest value to the provided one in the attribute domain.
|
QuantileListVisitor |
Obtains the data needed for a Quantile operation (classification of features into classes of
equal size).
|
StandardDeviationVisitor |
Determines the standard deviation.
|
StandardDeviationVisitor.Result | |
SumAreaVisitor |
Calculates the Sum of Areas for geometric fields
|
SumVisitor |
Calculates the Sum of an attribute (of a FeatureVisitor)
|
SumVisitor.SumResult | |
UniqueCountVisitor |
Determines the number of unique features in the collection on the basis of the specified feature
attribute.
|
UniqueVisitor |
Generates a list of unique values from a collection
|
UniqueVisitor.UniqueResult |
Enum | Description |
---|---|
