Grails How to use Date.ClearTime() without affect on Domain Object Value












0















I'm trying to get date without time using following code.



List<Person> personList = Person.createCriteria().list(){
eq("deleted", false)
order("datetime","desc")
}

def dateTimeSet = new HashSet()

personList.each { personInstance ->

Date originalDate = personInstance?.datetime

println("Before Date In Instance: "+personInstance?.datetime)

if(!dateTimeSet.contains(originalDate?.clearTime())){
dateTimeSet.add(originalDate?.clearTime())
}

println("After Date In Instance: "+personInstance?.datetime)

}


OUTPUT:



Before Date In Instance: Thu Sep 20 18:34:11 IST 2018
After Date In Instance: Thu Sep 20 00:00:00 IST 2018


How the personInstance gets updated when I'm using clearTime() in originalDate object.



Let me know how to use clearTime() here without change in domain instance.
