[ http://issues.apache.org/jira/browse/TUSCANY-547?page=comments#action_12422591 ] Geoff Winn commented on TUSCANY-547: ------------------------------------
I'm looking into this. > Discriminated types > ------------------- > > Key: TUSCANY-547 > URL: http://issues.apache.org/jira/browse/TUSCANY-547 > Project: Tuscany > Issue Type: Improvement > Components: C++ SDO > Environment: all > Reporter: Ed Slattery > > There are macros in the SDO code in data object, and lists/sequences to > handle the many get/set/add/insert APIS for each type if data object. These > are a pain to debug, and the conversion routines in TypeImpl are necessarity > duplicased for each type of data object. > One suggested approach which appeals would be to define a content holder > class, which would hold the value of any type of data object. By allowing it > to be constructed from any incoming type, we could reduce the get/set methods > to oneline methods which set up this generic blob, flag its original type, > and pass it on to a generic setter/getter. > Similarly the conversion routines could query the current type of the blob, > and perform the correct conversion for the blob to the requested type. > This would reduce the codebase, make it cleaner. > Also, we dont deal with XSD Unions at present, but having this blob in place, > we could extend the flag saying what type it is, to be perhaps a bitmask > saying what types if could be, and what type it is currently - this would > make unions supportable. -- 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]
