Nullsafe's notion of initialization augments Java's one in the following way:</p><ol><li>A method is considered "initializer" if it is either marked as <code>@Initializer</code> or is in the list of known initializer methods (e.g. onCreate()).</li><li>For each constructor, Nullsafe assumes all initializer methods will be called after the constructor is called. (Nullsafe does not check if this assumption is indeed true).</li><li>Nullsafe uses assumption 2, in order to check if class fields were initialized or not. (a non-nullable field is considered not initialized if it is not initialized in at least one constructor).</li></ol></aside><dl><dt class="spec value" id="val-final_initializer_typestates_lazy"><a href="#val-final_initializer_typestates_lazy" class="anchor"></a><code><span class="keyword">val</span> final_initializer_typestates_lazy : <a href="../../IR/Tenv/index.html#type-t">IR.Tenv.t</a> <span>-></span> <a href="../../IR/Procname/index.html#type-t">IR.Procname.t</a> <span>-></span> <a href="../../IR/Procdesc/index.html#type-t">IR.Procdesc.t</a> <span>-></span> <span>(bool <span>-></span> <a href="../../IR/Procname/index.html#type-t">IR.Procname.t</a> <span>-></span> <a href="../../IR/Procdesc/index.html#type-t">IR.Procdesc.t</a> <span>-></span> <span><span class="type-var">'a</span> option</span> <span>-></span> <span class="type-var">'b</span> * <span><span class="type-var">'c</span> option</span>)</span> <span>-></span> <span><span><span>(<a href="../../IR/Procname/index.html#type-t">IR.Procname.t</a> * <span class="type-var">'c</span>)</span> list</span> lazy_t</span></code></dt><dd><p>Typestates after the current constructor and all initializer procedures.</p></dd></dl><dl><dt class="spec value" id="val-final_constructor_typestates_lazy"><a href="#val-final_constructor_typestates_lazy" class="anchor"></a><code><span class="keyword">val</span> final_constructor_typestates_lazy : <a href="../../IR/Tenv/index.html#type-t">IR.Tenv.t</a> <span>-></span> <a href="../../IR/Procname/index.html#type-t">IR.Procname.t</a> <span>-></span> <span>(bool <span>-></span> <a href="../../IR/Procname/index.html#type-t">IR.Procname.t</a> <span>-></span> <a href="../../IR/Procdesc/index.html#type-t">IR.Procdesc.t</a> <span>-></span> <span><span class="type-var">'a</span> option</span> <span>-></span> <span class="type-var">'b</span> * <span><span class="type-var">'c</span> option</span>)</span> <span>-></span> <span><span><span>(<a href="../../IR/Procname/index.html#type-t">IR.Procname.t</a> * <span class="type-var">'c</span>)</span> list</span> lazy_t</span></code></dt><dd><p>Typestates after all constructors.</p></dd></dl></div></body></html>
