Process (Groovy Documentation)

geoscript.process.Process

A Process is a way of packaging spatial algorithms. You can create a GeoScript Process by name and get access to all of the built in GeoTool's Processes:

 def p = new Process("gs:Bounds")
 Map results = p.execute(["features": layer])

Or you can create a new Process using a Groovy Closure:

 Process p = new Process("convexhull",
   "Create a convexhull around the features",
   [features: geoscript.layer.Cursor],
   [result: geoscript.layer.Cursor],
   { inputs ->
       def geoms = new GeometryCollection(inputs.features.collect{f -> f.geom})
       def output = new Layer()
       output.add([geoms.convexHull])
       [result: output]
   }
 )
 Map results = p.execute(["features": layer])
