But before you do, change "refcount" to "references". I just committed
that to CVS to confuse everybody. :-)
props.globals.getNode("/sim/aircraft").getAttribute("references")
does now return the reference counter -- the number of co-owners
of the shared pointer. This is really only useful for debugging.
And here's again a summary of all the attribute names:
children ... returns number of children (faster than size(n.getChildren()!)
listeners ... return number of attached listeners
references ... returns number of co-owners (+ 2 for own consumption)
tied ... returns whether a node is "tied" (in which case listeners
might not get triggered)
alias ... whether the node is an alias to another node
read ... whether the node is read-protected
write ... whether the node is write-protected
archive ... whether the "archive" flag is set, which makes the
node saved with "Save Flight" in the menu
trace-read ... whether the node is being traced for read operations
trace-write ... whether the node is being traced for write operations
userarchive ... whether the node will be saved to ~/.fgfs/autosave.xml
on exit
