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

As Date.clearTime()
modifies the underlying instance, you should be creating a copy of it:
Date originalDate = personInstance?.datetime
if( !originalDate ) return
Date date = new Date( originalDate.time ).clearTime()
dateTimeSet << date

As Date.clearTime()
modifies the underlying instance, you should be creating a copy of it:
Date originalDate = personInstance?.datetime
if( !originalDate ) return
Date date = new Date( originalDate.time ).clearTime()
dateTimeSet << date
