Allow CalendarType.set to accept Date objects --------------------------------------------- Key: HHH-1052 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1052 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.1 rc 1 Environment: Hibernate 3.1RC1, MySQL 4.1, Windows XP Reporter: Adam Greene Priority: Minor Original Estimate: 5m Remaining Estimate: 5m CalendarType.set expects only Calendar objects as input. But when you are building Criterias with complex requirements, you many times use a Calendar object to do the calculations, and it would be nice to be able to pass Calendar.getTime() (which returns java.util.Date) to the Restrictions methods, because otherwise you end up passing the same Calendar object two seperate calls and you change the values in between calls, resulting in possible unexpected behaviour. Example (though a bit contrived does show what I am talking about): Calendar startcal = Calendar.getInstance(); Calendar endcal = Calendar.getInstance(); startcal.set(Calendar.DAY_OF_MONTH, 1); endcal.set(Calendar.DAY_OF_MONTH, 10); Criterion startin = Restrictions.between("start", startcal, endcal); startcal.set(Calendar.DAY_OF_MONTH, 10); endcal.set(Calendar.DAY_OF_MONTH, 30); Criterion endin = Restrictions.between("end", startcal, endcal); This might cause unexpected behaviour, but : Criterion startin = Restrictions.between("start", startcal.getTime(), endcal.getTime()); startcal.set(Calendar.DAY_OF_MONTH, 10); endcal.set(Calendar.DAY_OF_MONTH, 30); Criterion endin = Restrictions.between("end", startcal.getTime(), endcal.getTime()); would not cause problems.
