Stub

Stub is an attribute which specifies that if a symbol is ever used, Needs should automatically be called on the context of the symbol.

This enables autoloading of packages when their symbols are first accessed.

Examples

Attributes[MyPackage`myFunction] = {Stub}

(* Check if a symbol has Stub attribute *)
MemberQ[Attributes[symbol], Stub]
