Returns an iterator triple that allows for loops to iterate over all key/value pairs in a table.
iteratorFunc, table, startState = pairs(table);
Example
local random_array = { mug = "coffee", [42] = "universe", testboolean = false }
for index,value in pairs(random_array) do
if (type(index) == "number") then
index = tostring(index)
elseif (type(index) == "boolean") then
if (index) then
index = "true"
else
index = "false"
end
end
DEFAULT_CHAT_FRAME:AddMessage(index.." : "..value)
end
Result:
mug : coffee 42 : universe true : false
would be output to the chat window.
