DB.getValue() parameter double-check

[Varsuuk]

[RESOLVED]

I see in the 5E addCharRef code the line:

for _,v in pairs(aCharClassNodes) do
local _,sExistingClassPath = DB.getValue(v, "shortcut", "", "");

I am not sure what the 2nd "" stands for. On the API page it only mentions 3 arguments.

I understand extras in Lua are "ignored", but checking in case it is because of an enhancement to the API that didn't make the web page.

Shortcut contains a "class" and "record" values.

local sClass, sRecord = DB.getValue(node, "shortcut", "", "");

DB.setValue(nodeClass, "shortcut", "windowreference", sClass, sRecord);

sClass = "item" or "charsheet" or "npc".
sRecord="item.id-00001" or "charsheet.id-00312"

I GET it now. I read the "function getValue( sourcenode, [subpath], [default] )" and would have expected: "function getValue( sourcenode, [subpath], [default, ...] )" or some symbology to indicate multiple defaults.
I knew it returned two values for this method (I print these generally to find out) but it never occurred to me that the it was for multiple "defaults" to return - which of course makes sense :)


The key, of course, that I missed being the "(s)" ;)
default (...) [optional] The value(s) to be returned if getValue fails. (node does not exist; or non-value node)




Thanks

Ah, yeah, the bits on the end set it's defaults if it's nil. That's why I almost ALWAYS use DB.getValue(node,"something","default") and never node.name.getValue(). I almost always want something back even if it's my default.
