Query

             PredicateEvaluator test,
             Path pathOutput,
             Path pathTmp,
             ExtractionPaths paths,

             boolean keepTmp,
             boolean fastRelationTests)

Create a query to extract data contained in an area from an extraction database.

Parameters:

queryEnvelope - the bounding envelope of the region to extract.

test - a PredicateEvaluator used for determining inclusion in the extract.

pathOutput - a path to a file to store output data in.

pathTmp - a directory to store intermediate, temporary files (pass null to use the system's default temporary storage, i.e. Files.createTempDirectory(String, FileAttribute...) will be used.)

paths - an ExtractionPaths object configured for an extraction database.

treeNames - the names of the files in the data tree.

relationNames - the names of the files in the relation batches.

inputFormat - the FileFormat of the database extract files.

outputConfigIntermediate - configuration for intermediate file storage

outputConfig - configuration for the final output file.

keepTmp - whether to keep temporary files after the extraction is done.

fastRelationTests - whether to include relations based on their bounding box (and not by evaluating their exact geometry).
