Feature Request: enumerates and field conversions
-------------------------------------------------
Key: OJB-24
URL: http://issues.apache.org/jira/browse/OJB-24
Project: OJB
Type: New Feature
Components: PB-API
Versions: 1.1 CVS
Reporter: Martin Taal
Priority: Minor
Hi,
In my model I have enumerates which are represented as a java object in memory.
An enumerate java object has an int and a String value. When the owner object
is persisted I want to convert the enumerate object to either the int or the
string and store it in a field. When the owner object is retrieved then the
primitive type database field should be translated into the enumerate object.
It seems logical to use fieldconversions to achieve this, however the field
conversion interface only passes the value from the database and from this
database value it can not be determined which Enumerate object should be
created. This is so because different enumeratetypes can have the same value
(with a different meaning). To identify which enumerate object should be
created the fieldconversion interface could be extended so that also the field
descriptor is passed.
This is really just a very-low-priority-nice-to-have because there are many
workarounds, e.g. store the enumerate class in the field also (etc.). But maybe
somebody else also requires it or this has come-up earlier or maybe field
conversions are looked at anyhow for a new larger release.
