Return versions of a @History entity bean.

Note that this query will work against view based history implementations but not sql2011 standards based implementations and we should use findVersionsBetween that requires a start and end timestamp to be specified.

Generally this query is expected to be a find by id or unique predicates query. It will execute the query against the history returning the versions of the bean.

findVersionsBetween

Return versions of a @History entity bean between the 2 timestamps.

Generally this query is expected to be a find by id or unique predicates query. It will execute the query against the history returning the versions of the bean between the start and end timestamps.

Timestamp start = ...;
Timestamp end = ...;

List<Version<Customer>> customerVersions =
  new QCustomer()
    .id.eq(42)
    .findVersionsBetween(start, end);

for (Version<Customer> customerVersion : customerVersions) {
  Customer bean = customerVersion.getBean();
  Map<String, ValuePair> diff = customerVersion.getDiff();
  Timestamp effectiveStart = customerVersion.getStart();
  Timestamp effectiveEnd = customerVersion.getEnd();
}
