Class TypeScript::VarTypeAccess

A possibly qualified name that refers to a variable from inside a type.

This can occur as

  • part of the operand to a typeof type, or
  • as the first operand to an is type.

For example, it may occur as the E in these examples:

var x : typeof E
function f(...) : E is T {}

In the latter case, this may also refer to the pseudo-variable this.
