Hi, I am wondering if there is a good reason that osgDB::writeNodeFile does not behave in the same manner as osgDB::readNodeFile in the sense that the former returns a bool when the latter returns an osg::Node*.
This prevents using pseudo-writers as pseudo-loaders (http://trac.openscenegraph.org/projects/osg//wiki/Support/KnowledgeBase/PseudoLoader) and to chain plugins calls. Imagine I want to write an obfuscator plugin; I would like to call osgconv mymodel.fmt myobfuscatedmodel.fmt.obfuscator to obfuscate data and osgconv mybfuscatedmodel.fmt.obfuscator myunobfuscatedmodel.fmt to un-obfuscate it. I can manually achieve that with something like Code: std::string realFileName = osgDB::getNameLessExtension(fileName); if(realFileName.empty()) return WriteResult::FILE_NOT_HANDLED; // obfuscator ref_ptr<Node> obfuscatedNode = obfuscateModel(node, parseOptions(options)); // forward writing to the "real" plugin ref_ptr<ReaderWriter> rw = getReaderWriter(realFileName); if(rw) { return rw->writeNode(*obfuscatedNode, realFileName, options); } else { return WriteResult::ERROR_IN_WRITING_FILE; } but it doesn't feel totally right. Note that I could use 2 seperate plugins, one for obfuscation and one for de-obfuscation, however, I might want my code to run *after* the osg::Optimizer and this requires for the plugin to be called at write time. Could we change osgDB::writeNodeFile signature or is it a bad idea? Thank you!
