Perform Pagination Manually on List in Grails
Posted By : Varun Sharma | 23-Apr-2014
We have Remote Pagination Plugin in Grails to carryout pagination operations but that is little bit complex to operate with. Also Remote Pagination mostly used in views to paginate through list.
But, what if we need pagination on a list manually like rewuest from mobile app etc. I went through this problem & solved by using the below piece of code.
def getPaginatedList(list, max, offset) {
max = Math.min(max ?: 10, 100)
offset = offset?:0
int total = list.size()
int upperLimit = (offset+max (greterThanEqualto) total?total:offset+max)-1
return offset (lessThan) total ? list.getAt(offset..upperLimit) : []
}
Just pass your list, give max count along with offset i.e; from where you want list to begin and this will return you list that is desired.
>Hope it helps !
