Title: How to get the count of objects?
Post by: kinglaw0577 on December 30, 2015, 07:47:35 am

I know  "operation_history" object is 1.11.x,I can use get_objects to get it,
but how to get the count of this?

What "count"?
if you need an identifier for that particular operation, it is the number that comes after "1.11."

He probably means the number of objects of that type.

As far as I know it's not possible, so you'll need to query objects in a loop until you find the first one that's undefined (or null or whatever the witness_node returns for objects that don't exist)

Yes,I want to get the recent n transactions,so I hope get  the last identifier of objects of that type.

Each account has a balance object that states the latest operation id that caused a change in your account .. i think it is 2.6.x with x being the id of your account 1.2.x
