Section Reflection

MyrScript reflection Reflective programming or reflection is the ability of a script to examine, introspect, ~~and modify~~ its own structure.

In other words, these functions answer questions like 'What are the properties of a Staff?'

These functions are not included in SMUtils, because rarely needed, and SMReflection.mys file is auto-generated.

Usage



 IncludeOnce("SMReflection")
 local tab = ReflectionGetFields("Staff")
 for i=1,getn(tab) do
   print(tab[i].." = ".. tostring(FrontScore().FirstStaff[tab[i]]))
 end
