design - Generic IOC resolving counterparts in other languages -

-

i've used methodology alot lately (c#) able decouple logic domain objects shouldn't reside inside domain object itself. find nice , clean.

how accomplish same in lets java or c++, etc? java doesn't have runtime generic type information method non existent there, can 1 same methodology?

example resolving menu items domain object. (could other things aswell eg. resolving validation rules etc.):

class domainobject {  }   interface imenuitem<t> {   string gettitle(t entity);   action<t> itemaction; }  class domainobjectmenuitem : imenuitem<domainobject> {   // menu item implementation domain object }   public void generateitems(object domainobject) {   type type = typeof(imenuitem<>).makegeneric(domainobject.gettype());   imenuitems[] items = container.resolveall(type);    // items }

java has many dependency injection frameworks (leads ioc) such spring , guice. can of course code hand, noone that. instead 1 uses framework, prescribed method of configuring such annotations or xml.

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
