Interface Summary

Interface	Description
VectorProcess	Marker interface for processes that should be grouped into the "vector" family.

Class Summary

Class	Description
AggregateProcess	Computes various attribute statistics over vector data sets.
AggregateProcess.AggregateResultsConverterFactory	Converter factory that converts AggregateProcess.Results to FeatureCollection.
AggregateProcess.Results	The aggregate function results
BarnesSurfaceInterpolator	Interpolates a surface across a regular grid from an irregular set of data points using the Barnes Surface Interpolation technique.
BarnesSurfaceProcess	A Process that uses a BarnesSurfaceInterpolator to compute an interpolated surface over a set of irregular data points as a GridCoverage.
BBOXExpandingFilterVisitor	A DuplicatingFilterVisitor which expands the BBOX of the filter by given distances for each box edge.
BilinearInterpolator	Interpolates a grid to a grid of different dimensions using bilinear interpolation.
BoundsProcess	Simple process with a ReferencedEnvelope as the output
BufferFeatureCollection	Buffers a feature collection using a certain distance
CentroidProcess	A process that returns the centroids for the geometries in the input feature collection.
ClassifyByRangeProcess	Computes a new attribute to classify another attribute by intervals over vector data sets.
ClipProcess	Modified version that can preserve Z values after the clip
CollectGeometries	Collects all geometries from the specified vector layer into a single GeometryCollection (or specialized subclass of it in case the geometries are uniform)
ContourProcess
Contours
CountProcess	Counts the elements in the collection (useful as a WFS sidekick)
FeatureClassStats	Process that classifies vector data into "classes" using one of the following methods: Equal Interval (EqualIntervalFunction) Quantile (QuantileFunction) Natural Breaks (JenksNaturalBreaksFunction)
FeatureClassStats.Results
FeatureProcess
GraticuleLabelPointProcess
GridProcess	A process that builds a regular grid as a feature collection
GroupCandidateSelectionProcess
HeatmapProcess	A Process that uses a HeatmapSurface to compute a heatmap surface over a set of irregular data points as a GridCoverage.
HeatmapSurface	Computes a Heat Map surface from a set of irregular data points, each containing a positive height value.
InclusionFeatureCollection	A process providing a feature collection containing the features of the first input collection which are included in the second feature collection
IntersectionFeatureCollection	A process providing the intersection between two feature collections
LRSGeocodeProcess
LRSMeasureProcess
LRSSegmentProcess
NearestProcess
PointBuffers	Generates a set of polygons, each representing the set of points within a given distance from the central point The data layer must be a point layer, the reference layer must be a polygonal one"
PointStackerProcess	A Rendering Transformation process which aggregates features into a set of visually non-conflicting point features.
ProcessingCollection<T extends FeatureType,F extends Feature>	Abstract base class to ease the implementation of a streaming processing collection, that is, one that tries to compute the results on the fly as the iterator is traversed.
ProcessTestUtilities
QueryProcess
RectangularClipProcess	A process clipping the geometries in the input feature collection to a specified rectangle
ReprojectProcess	Will reproject the features to another CRS.
SimpleProcessingCollection	The simple feature version of ProcessingCollection.
SimplifyProcess	A process simplifying the geometries in the input feature collection according to a specified distance, and using either a topology preserving or a Douglas-Peuker algorithm
SnapProcess
TransformProcess	Used to transform a feature collection as defined using a series of expressions.
TransformProcess.Definition	Definition of an attribute used during transform
UnionFeatureCollection	A process providing the union between two feature collections
UniqueProcess	Returns the unique values of a certain attribute
VectorProcessFactory	Factory providing a number of processes for working with feature data.
VectorToRasterProcess	A Process to rasterize vector features in an input FeatureCollection.
VectorZonalStatistics	Provides statistics for the distribution of a certain quantity in a set of reference areas.
