Node loader implementation for data files. Data files are |
4740 |
05 Feb 09 |
nicklas |
normally loaded as an end-point folder node with one child entry |
4740 |
05 Feb 09 |
nicklas |
for each data file. The exception is if there is only one file, |
4740 |
05 Feb 09 |
nicklas |
in which case the file node itself is loaded. It can never be |
4740 |
05 Feb 09 |
nicklas |
root node or a forward/reverse-loading node. |
