This function is designed to make long If statements quicker and easier. Allows you to check lots of values at once for the same type

<PREFIX>_allAreType(type, param [,param [, ...]])

Note:

If just the type parameter is given then the function returns true, as no parameters have failed the check (See example 'c' below).

Function Parameters

Arguments

type

String - A string that represents the desired type of the values. See type() for further help on this value.

param

any - A list of values to check for the same, consistent type.

Returns

result

Boolean - true if all of the params have the desired type, false if atleast one fails.

Example

local a = <PREFIX>_allAreType("string", "Hello", DEFAULT_CHAT_FRAME:GetName())
local b = <PREFIX>_allAreType("number", 65, tonumber("two"))
local c = <PREFIX>_allAreType("table", {}, {5, 3, "Hello"}, "Bob")

-- edge cases
local d = <PREFIX>_allAreType("function")
local e = <PREFIX>_allAreType("function", nil)

Result

a = true
b = false
c = false

-- edge cases
d = true
e = false

Code

function <PREFIX>_allAreType(typeStr, ...)
  local value
  for i = 1, select('#', ...) do
    value = select(i, ...)
    if type(value) ~= typeStr then
      return false
    end
  end
  return true
end
