Usage API Paging question

[Nik Martin <ni...@nfinausa.com>]

Could someone post some pseudocode on how to use paging when processing 
usage reports? I'm having a bit of trouble getting my head wrapped around 
this.

Here's pseudocode for what I have right now:
default.page.size: 2000

var page=1
usage = api.listusage{domain:xxx, page:page, pagesize: 2000, 
startdate:xx-xx-xxxx, enddate: xx-xx-xxxx};

while usage.length = 2000{
 	//there are more records
 	page+=1;
 	usage= usage + api.listusage{domain:xxx, page:page, pagesize: 
2000,
startdate:xx-xx-xxxx, enddate: xx-xx-xxxx};
}

Is this in line with what I should be doing?  As long as the number of 
records is 2000, it can be assumes that there are more records, so I 
should fetch until usage.length < 2000.


Regards,

Nik

[KK]  This should instead be: usage= api.listusage{domain:xxx, page:page, pagesize: 2000, startdate:xx-xx-xxxx, enddate: xx-xx-xxxx};

[KK] Yes, you need to fetch until length < 2000
