Examples of com.j256.ormlite.examples.datapersister.MyDatePersister

com.j256.ormlite.stmt.query.OrderBy
A custom persister that tweaks how the Date is stored in the database. If the date is before 1970 then this just return null instead of throwing some sort of out-of-range error. This is useful because sometimes we get low values of SQL timestamps that are stored in existing schemas which can't be mapped to a Date.
You would not want this to override the default behavior for Date so you would use this by specifying the class in {@link DatabaseField#persisterClass()}.
