com.google.javascript.rhino.jstype.JSType
Represents JavaScript value types.
Types are split into two separate families: value types and object types. A special {@link UnknownType} exists to represent a wildcard type on whichno information can be gathered. In particular, it can assign to everyone, is a subtype of everyone (and everyone is a subtype of it).
If you remove the {@link UnknownType}, the set of types in the type system forms a lattice with the {@link #isSubtype} relation defining the partialorder of types. All types are united at the top of the lattice by the {@link AllType} and at the bottom by the {@link NoType}.

        "/** @return {number} */ extern.one;",
        "/** @type {Object} */ var normal;" +
        "/** @return {number} */ normal.one;", null);


    JSType e = globalScope.getVar("extern").getType();
    assertFalse(e.dereference().hasOwnProperty("one"));


    JSType normal = globalScope.getVar("normal").getType();
    assertFalse(normal.dereference().hasOwnProperty("one"));
