Re: How to strip off selected columns from a criteria object

[wzhao6...@gmail.com]

Hi Thomas,

Thanks a lot, just tried this, worked like a charm.
BTW, Criteria object returned by criteria.clone() gets affected if the
original criteria object is modified. Is this a bug?
For examples, if I have an existing criteria, then I do:
Criteria criteriaClone = criteria.clone();
criteria.getSelectColumns().clean();

both criteria and criteriaClone have empty selectcolumn list.
Thanks,



David

  Thanks for your reply. But what I need to deal with is that:
 I have a criteria object, with joins, and where clauses and a list of
 columns to select, and I need to remove all the selected columns in the
 criteria, both selected column, and as columns, so I can use OMPeer class
 to
 select a list of OM objects;


 What happens if you do criteria.getSelectColumns().clear() or
 criteria.getAsColumns().clear(), respectively? Would that help?
 (This is what is basically done in criteria.clear(), among other things)


 Bye, Thomas.

how to contruct an object extending com.workingdogs.village.Record from a Record

[wzhao6...@gmail.com]

Hi there,

I need to create a class, say BetterRecord, that extends
com.workingdogs.village.Record. I couldn't figure out how to construct a
BetterRecord object from an existing com.workingdogs.village.Record.

public class BetterRecordextends Record {
   public RetterRecord (Record r) {
  ???
   }
 public String getThings() {
  return this.things;
 }
 public void setThings(String str) {
  this.things = str;
 }
}

Thanks very much!

David
