Subject [jira] Created: (TORQUE-100) clone() method for Criteria
Date Tue, 31 Jul 2007 13:02:53 GMT
clone() method for Criteria

                 Key: TORQUE-100
                 URL: https://issues.apache.org/jira/browse/TORQUE-100
             Project: Torque
          Issue Type: Wish
            Reporter: Tamas Ruff


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

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?
