Hi All, Can anyone tell me whether there is a way (call) in OSG to say what type of object a plugin will produce ? i.e. if I have a file "A.jpg" and I call osgDB::Registry::instance()->getReaderWriterForExtension passing in the file extension, I get the readerwriter. What I would like to know is what ObjectType that readerwrite would return.
The reason for the question is I'm updating the ReaderWriterZip plugin to handle in-memory zip extraction, and I want to be able to give it a zip file that contains many files of varying format. Rippling through the zip file I can get the individual files, and their content, and unzip them in memory, but the issue I have is that I don't really want to have a big If statement in the plugin to look at the known file extensions and to say whether I should be calling ReadNode or ReadImage. I would like to be able to enquire the type of Object that the reader would produce, and then have a simple switch statement like the Curl plugin. One route I thought of would be to add to extend each plugin to have a function based that returns the type of object, and I guess this would be fairly straight forward, but before delving in, I just wanted to check if there is a method already available. Many thanks for any help. Neil. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
