Hi,
I noticed that when ReaderWriters return a ReadStatus::FILE_NOT_FOUND for a
file, the osgDB::Registry keeps checking with other ReaderWriters, then
generates library names for that file extension, and tries to load those
DLLs/SOs.
The code that does the checking is
// first attempt to load the file from existing ReaderWriter's
AvailableReaderWriterIterator itr(_rwList, _pluginMutex);
for(;itr.valid();++itr)
{
ReaderWriter::ReadResult rr = readFunctor.doRead(*itr);
if (readFunctor.isValid(rr)) return rr;
else results.push_back(rr);
}
in ReaderWriter::ReadResult Registry::read(const ReadFunctor& readFunctor)
Now, since ReaderWriters return FILE_NOT_HANDLED when they aren't meant for
that file-type, but can return FILE_NOT_FOUND when the search for the file
fails, the other ReaderWriters need not be checked.
Attaching an empty osg::Node object to the result to avoid checking the other
ReaderWriters would be inefficient. And the receiving NodePaths would need to
write the code to handle these empty osg::Node objects too.
Any other opinions?
Thank you!
Cheers,
Anish
