> Hi,
> I want to create a org.apache.torque.util.Criteria object from a (possible
> complicated) textual expression: this is made using a parser and an
> interpreter for a textual expression using brackets and different operators.
> During the creation of the org.apache.torque.util.Criteria object several
> database select operations are made (among others replacing some textual
> labels from the original textual expression with their corresponding IDs form
> different database tables).
> Thereafter I have to use the resulting Criteria object several times as a
> base for creating further Criteria objects. For that the clone() method would
> be the ideal candidate...
> But as I see the clone() method is not yet implemented for the Criteria class.
> I want to avoid the "parsing-interpreting-replacing labels with IDs" phase
> for each new Criteria object needed because they are time-consuming
> operations. Other alternative would be the use of
> org.apache.commons.lang.SerializationUtils, but this is also quite slow.
> Do you plan to implement the clone() method in the near future?
