support IncrementalSortPath type in outNode()
Started by Hou, Zhijieabout 5 years ago2 messages
Hi,
I found IncrementalSortPath type is not analyzed in outNode.
It does not matter during runtime though.
Just for the convenience of debugging,
when debug by gdb, we can use "call pprint(incresortpath)" to list the node info.
So I try to support IncrementalSortPath in outNode.
Best regards,
houzj
