public class FootprintsTransformation extends FunctionImpl implements CoverageReadingTransformation
Transformation returning the same granules that theStructuredGridCoverage2DReader
would have used as the input for image creation in theGridCoverage2DReader.read(GeneralParameterValue[])
method (with some exceptions, like footprints usage, as this transformation only sets up a filter against the associatedGranuleSource
).

evaluate
public SimpleFeatureCollection evaluate(Object object)
Description copied from class:FunctionImpl
Default implementation simply returns the fallbackValue.Please override this method to produce a value based on the provided arguments.
- Specified by:
evaluate
in interfaceExpression
- Overrides:
evaluate
in classFunctionImpl
- Parameters:
object
- Object being evaluated; often a Feature- Returns:
- value for the provided object

invertQuery
public Query invertQuery(Query targetQuery, GridGeometry gridGeometry)
Description copied from interface:RenderingTransformation
Given a target query and a target grid geometry returns the query to be used to read the input data of the function This method will be called only if the input data is a feature collection.- Specified by:
invertQuery
in interfaceRenderingTransformation
- Returns:
- The transformed query, or null if no inversion is possible/meaningful
-
invertGridGeometry
public GridGeometry invertGridGeometry(Query targetQuery, GridGeometry targetGridGeometry)
Description copied from interface:RenderingTransformation
Given a target query and a target grid geometry returns the grid geometry to be used to read the input data of the function involved in rendering. This method will be called only if the input data is a grid coverage or a grid coverage reader- Specified by:
invertGridGeometry
in interfaceRenderingTransformation
- Returns:
- The transformed query, or null if no inversion is possible/meaningful
