Hola Martin, See you're back.
I meant setting the whole array to null. When setting one of the elements, there's no problem. For example, If I have a class disc and a class discography that has an array of discs as attribute, I can perfectly set any of the components to null. Also if I set the array to null doing setDiscs(null), there is no problem. The element is generated in the message. If I don't call setDiscs(), the element will be generated anyway. But if I create a class Elvis that extends discography and I don't call setDiscs(), the element won't be generated in the message. If instead I call setDiscs(null), the element will be generated. It works anyway but the behaviour is different. If element is generated, the client will interpret that discs has one component that is null discs[0]=null. If element is not generated, the client will interpret that discs=null. I thought that the correct behaviour should be the second: as the whole array is null, it won't generate any element in the message for that and the client will interpret that the array is null. Or in the second case, in spite of generating the element in the message, the client should interpret that the array is null Thanks, Jorge Fernández Martin Gainty <[EMAIL PROTECTED]> escribió: Jorge Looking for specifics on what you mean by "setting it" do you mean setting the array to null or one of the elements in the array? NULL is a representation of an uninitialised object the treatment of this uninitialised object is language dependent that said an Array of NULL objects is an allocated array object of uninitialised empty objects so..a java.lang.Arrays is an *allocated object*( which is represented by the Javadoc available here http://java.sun.com/j2se/1.5.0/docs/api/ To add more even more confusion Arrays of primitive types (ints/chars) are different than arrays of Objects which are pre-allocated entities http://java.sun.com/docs/books/jni/html/objtypes.html An Array of primitive types allocation is dependent on the number of elements BUT any array of pre-defined size is allocated http://java.sun.com/docs/books/jni/html/objtypes.html In JavaScript world the treatment of Arrays is even dependent on the browser JavaScript version e.g. Mozilla JavaScript1.2 converts an Array object to its length. Mozilla JavaScript1.1, JavaScript1.3-JavaScript1.5 converts an empty Array to 0 HTH/ Martin Gainty ______________________________________________ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.
