clone() method for Criteria
---------------------------
Key: TORQUE-100
URL: https://issues.apache.org/jira/browse/TORQUE-100
Project: Torque
Issue Type: Wish
Reporter: Tamas Ruff
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?
