at first, I cant speak english very well.
I tried to LazyContainer.
There are JPAContainer or SQLContainer, but I like DAO-style Container.
so I tried this.
In this implementation, each table scroll needs just 3 DAO method calling.
first, for calling Container.size() second, for calling Container.getIdByIndex() third, for calling Container.getItemIds()
I separate this implementation to two part. so this jar contains just one interface for DAO. another jar contains LazyContainer.
I cant explain more detail. I'm sorry.
