For instance you get (EditablePriceableItem a, EditablePriceableItem b) as parameters of a function. The only you know about it is that they are instances of EditablePriceableItem. Thus when copying a to b using introspections you don't want to alter properties that are outside of your scope: here the interface EditablePriceableItem. A 3rd argument, as you propose (and as proposed in enhancement 32642), would do the job. Neverthless, getting a list of property names from an interface that potentially extends several other interfaces is not trivial. It would then be very handy to have an helper method such as: getReadableProperties(Class aclass): List/or array getSettableProperties(Class aclass): List/or array -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
