Interface Rows<T>

  • Type Parameters:
    T - The type managed by the Rows.
    All Superinterfaces:
    HeaderAccessor<T>, Iterator<Row<T>>
    All Known Implementing Classes:
    RowsImpl
    public interface Rows<T>
extends HeaderAccessor<T>, Iterator<Row<T>>
    A bunch of Row instances is represented by a Rows instance. As of efficiency reasons, a Rows instance can be iterated through, returning a single Row within each iteration. This approach is making it possible to query a DB in the background and just hold the Row instances being served next in the Rows instance (in memory).

    The way how Rows instances manage their related Row instances is implementation specific, a plain java implementation might use some kind of collection for storing the Row instances (this can get memory intensive and not applicable when working with big data). A DB implementation might retrieve the Row instances in blocks one by one, one after the other, by querying the DB accordingly (in terms of "next" result sets).
