Do I get you right, you'd like a hard-coded method in the generated
TableNameRecord that does the mapping for the generated POJO? E.g.
class TableNameRecord extends UpdatableRecordImpl {
...
public TableNamePojo intoTableNamePojo() { ... }
public void fromTableNamePojo(TableNamePojo pojo) { ... }
}
Would this really help? I can definitely see the into() method. The from()
method doesn't seem to add that much value over the existing
Record.from(Object) method, except, perhaps, some additional type safety?

Oh, I see, that's a different story, though. The problem is that
fetchInto(Class) is called on a ResultQuery<R>, where R is a generic type.
It will be a bit harder to find a solution along the lines of what you're
looking for. Perhaps, we could generate a RecordMapper<TableNameRecord,
TableNamePojo>, which would add some type safety over passing the class
literal (and it could be implemented more optimally). That RecordMapper
could then be made available from TableNameRecord:
class TableNameRecord extends UpdatableRecordImpl {
...
public static RecordMapper<TableNameRecord, TableNamePojo> mapper() {
... }
}
This could then be used as such:
dsl.select(...).from(...).fetchInto(TableNameRecord.mapper())
What do you think?
