Orbisprocess

[ebocher]

I share here some examples about orbisprocess library. A library to write process based on orbiswps job and the famous geoscript library.

//Declare
Process p = new Process([inputA: String],[outputA: String], { inputA ->
          [outputA: inputA.trim]
         }
         )
//Execute
 p.execute([inputA : 'OrbisGIS is nice'])

Note that the input and output parameters must be controlled.

The input and output types could be dynamically extended using an OSGI service registry.

//Compute a buffer around a geometry and returns a new geometry
//Geometry types supported are JTS Geometry classes
 Process p = new Process("Create a buffer around a geometry",[inputA: Geometry, distance: double], [outputA: Geometry], { inputA, distance ->
             [outputA: inputA.buffer(distance)]
         }
         )
         p.execute([inputA : new WKTReader().read("POINT(10 1)")] )] )

//Example with a table from H2GIS
def h2GIS = H2GIS.open([databaseName: './target/loadH2GIS'])
         h2GIS.execute("""
                DROP TABLE IF EXISTS h2gis, super;
                CREATE TABLE h2gis (id int, the_geom point);
                INSERT INTO h2gis VALUES (1, 'POINT(10 10)'::GEOMETRY), (2, 'POINT(1 1)'::GEOMETRY);
        """)

         Process p = new Process([inputA: ITable],[outputA: String], { inputA ->
             [outputA: inputA.columnNames]
         }
         )
         p.execute([inputA : h2GIS.getSpatialTable("h2gis")])

//An advanced type of the String with custom parameters
//Custom parameters must be controlled, thanks to the Caster.class
 Process p = new Process([inputA: [title:'My input', type : String, minOccurs=1 maxOccurs=1] ],[outputA: String], { inputA ->
             [outputA: inputA.columnNames]
         }
         )
         p.execute([inputA : "A string value"])

Below a possible list of input types

[title : "A title", type : BoudingBox, supportedCRS = {"EPSG:4326", "EPSG:2000", "EPSG:2001"}, dimension = 2]

[title : "A title", type : RawData, multiSelection = true, isDirectory = false, isFile = false,excludedTypes = {".sql", ".shp"}, fileTypes = {".dbf", ".txt"}]

[title : "A title", type : EnumData, isEditable = true, multiSelection = true, values = {"value1", "value2"}, names = {"name1","name2"}]

A new use case

@Test
    void testSimpleProcess5(){
        def process = processFactory.create(
                "title",
                [inputA : String[]],
                [outputA : String],
                { inputA -> [outputA : inputA[1]] }
        )
        process.execute([inputA :["A", "B", "C"]])
        assertEquals "B", process.getResults().outputA
    }

Next use case will be added directly to the test files.
