Class DateGen

java.lang.Object

org.apache.drill.exec.store.mock.DateGen

All Implemented Interfaces:

FieldGen

public class DateGen
extends Object
implements FieldGen

Very simple date value generator that produces ISO dates uniformly distributed over the last year. ISO format is: 2016-12-07.

There are many possible date formats; this class does not attempt to generate all of them. Drill provides a date type, but we use a string format because example cases from people using the product often read text files. Finally, we (reluctantly) use the old-style date formats instead of the new Java 8 classes because Drill prefers to build with Java 7.
