Thomas Vandahl closed TORQUE-23. -------------------------------- > DeepCopy > -------- > > Key: TORQUE-23 > URL: http://issues.apache.org/jira/browse/TORQUE-23 > Project: Torque > Issue Type: New Feature > Components: Generator > Reporter: Thoralf Rickert > Assigned To: Thomas Fischer > Priority: Minor > Fix For: 3.3 > > Attachments: patch.txt > > > I've a small problem with the copy() and copyInto() methods in the generated > Torque objects. I've tables with dependencies from other tables (for example > a table "login" which has a foreign key to a table "address"). I want to use > the BaseAddress.copy() method to copy the address object and save it. If I > use this method, it also loads and copies internally all logins which are > linked to the source address to the new address. So, it makes a deep copy. > If the object "Address" has many hundreds related objects of "Login" this > deep copy makes a lot that is sometimes not necessary. So, it's better to let > the user/programmer decide if there program should do a deep copy or not. > The best way would be, that there is a copy(boolean) method that should be > added during BaseAddress generation. I think, it's not very complicated to > add this "feature". Here is my proposal: > 1. add in Object.vm a new boolean parameter to copy() like this > public $table.JavaName copy(boolean deepcopy) throws TorqueException > { > return copyInto(new ${table.JavaName}(),deepcopy); > } > 2. create two new downwards compatible methods copy() and copyInto() > public $table.JavaName copy() throws TorqueException > { > return copy(true); > } > protected $table.JavaName copyInto($table.JavaName copyObj) throws > TorqueException > { > return copyInto(copyObject, true); > } > 3. add a new parameter deepcopy to the old copyInto() method and check that > variable before making the > deepcopy. I think, it's not necessary to submit that value recursivly to > the referers. > protected $table.JavaName copyInto($table.JavaName copyObj, boolean) > throws TorqueException > { > .... > #if ($complexObjectModel) > if (deepcopy) { > #foreach ($fk in $table.Referrers) > ... > #end > } > #end > } > Maybe I can create a patch for you. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
