T
- The type managed by the Records
.public interface Records<T> extends Iterator<Record<? extends T>>
Record
instances is represented by a Records
instance. As of efficiency reasons, a Records
instance can be
iterated through, returning a single Record
within each iteration.
This approach is making it possible to query a DB in the background and just
hold the Record
instances being served next in the Records
instance (in memory).
The way how Records
instances manage their related Record
instances is implementation specific, a plain java implementation might use
some kind of collection for storing the Record
instances (this can
get memory intensive and not applicable when working with big data). A DB
implementation might retrieve the Record
instances in blocks one by
one, one after the other, by querying the DB accordingly (in terms of "next"
result sets).forEachRemaining, hasNext, next, remove
