<p>If a factory is destroyed, then any pending callbacks will be cancelled preventing any bound member functions from being called.

<p><b>Note: </b><code>CompletionCallbackFactory<T></code> isn't thread safe, but it is somewhat thread-friendly when used with a thread-safe traits class as the second template element. However, it only guarantees safety for creating a callback from another thread, the callback itself needs to execute on the same thread as the thread that creates/destroys the factory.

<a class="code" href="classpp_1_1_completion_callback_factory.html" title="CompletionCallbackFactory<T> may be used to create CompletionCallback objects that are bound to membe...">pp::CompletionCallbackFactory<MyClass></a> factory_;
};
</pre></div><p><b>Passing additional parameters to your callback</b></p>
<p>As a convenience, the <code><a class="el" href="classpp_1_1_completion_callback_factory.html" title="CompletionCallbackFactory<T> may be used to create CompletionCallback objects that are bound to membe...">CompletionCallbackFactory</a></code> can optionally create a closure with up to three bound parameters that it will pass to your callback function. This can be useful for passing information about the request to your callback function, which is especially useful if your class has multiple asynchronous callbacks pending.</p>
<p>For the above example, of opening a file, let's say you want to keep some description associated with your request, you might implement your OpenFile and DidOpen callback as follows:</p>
<div class="fragment"><pre class="fragment"> <span class="keywordtype">void</span> OpenFile(<span class="keyword">const</span> <a class="code" href="classpp_1_1_file_ref.html" title='The FileRef class represents a "weak pointer" to a file in a file system.'>pp::FileRef</a>& file) {
std::string message = <span class="stringliteral">"Opening file!"</span>;
<a class="code" href="classpp_1_1_completion_callback.html" title="This API enables you to implement and receive callbacks when Pepper operations complete asynchronousl...">pp::CompletionCallback</a> cc = factory_.NewCallback(&MyClass::DidOpen,
message);
int32_t rv = file_io_.Open(file, PP_FileOpenFlag_Read, cc);
CHECK(rv == PP_OK_COMPLETIONPENDING);
}
<span class="keywordtype">void</span> DidOpen(int32_t result, <span class="keyword">const</span> std::string& message) {
<span class="comment">// "message" will be "Opening file!".</span>
...
}
</pre></div><p><b>Optional versus required callbacks</b></p>
<p>When you create an "optional" callback, the browser may return the results synchronously if they are available. This can allow for higher performance in some cases if data is available quickly (for example, for network loads where there may be a lot of data coming quickly). In this case, the callback will never be run.</p>
<p>When creating a new callback with the factory, there will be data allocated on the heap that tracks the callback information and any bound arguments. This data is freed when the callback executes. In the case of optional callbacks, since the browser will never issue the callback, the internal tracking data will be leaked.</p>
<p>Therefore, if you use optional callbacks, it's important to manually issue the callback to free up this data. The typical pattern is:</p>
<div class="fragment"><pre class="fragment"> <a class="code" href="classpp_1_1_completion_callback.html" title="This API enables you to implement and receive callbacks when Pepper operations complete asynchronousl...">pp::CompletionCallback</a> callback = callback_factory.NewOptionalCallback(
&MyClass::OnDataReady);
int32_t result = interface->GetData(callback);
<span class="keywordflow">if</span> (result != PP_OK_COMPLETIONPENDING)
callback.<a class="code" href="classpp_1_1_completion_callback.html#a7795404cc15a4f96523c28db21d364c4" title="Run() is used to run the CompletionCallback.">Run</a>(result);
</pre></div><p>Because of this additional complexity, it's generally recommended that you not use optional callbacks except when performance is more important (such as loading large resources from the network). In most other cases, the performance difference will not be worth the additional complexity, and most functions may never actually have the ability to complete synchronously.</p>
<p><b>Completion callbacks with output</b></p>
<p>For some API calls, the browser returns data to the caller via an output parameter. These can be difficult to manage since the output parameter must remain valid for as long as the callback is pending. Note also that CancelAll (or destroying the callback factory) does <em>not</em> cancel the callback from the browser's perspective, only the execution of the callback in the plugin code, and the output parameter will still be written to! This means that you can't use class members as output parameters without risking crashes.</p>
<p>To make this case easier, the <a class="el" href="classpp_1_1_completion_callback_factory.html" title="CompletionCallbackFactory<T> may be used to create CompletionCallback objects that are bound to membe...">CompletionCallbackFactory</a> can allocate and manage the output data for you and pass it to your callback function. This makes such calls more natural and less error-prone.</p>
<p>To create such a callback, use NewCallbackWithOutput and specify a callback function that takes the output parameter as its second argument. Let's say you're calling a function GetFile which asynchronously returns a <a class="el" href="classpp_1_1_file_ref.html" title='The FileRef class represents a "weak pointer" to a file in a file system.'>pp::FileRef</a>. GetFile's signature will be <code>int32_t GetFile(const CompletionCallbackWithOutput<pp::FileRef>& callback);</code> and your calling code would look like this:</p>
<div class="fragment"><pre class="fragment"> <span class="keywordtype">void</span> RequestFile() {
file_interface->GetFile(callback_factory_.NewCallbackWithOutput(
&MyClass::GotFile));
}
<span class="keywordtype">void</span> GotFile(int32_t result, <span class="keyword">const</span> <a class="code" href="classpp_1_1_file_ref.html" title='The FileRef class represents a "weak pointer" to a file in a file system.'>pp::FileRef</a>& file) {
<span class="keywordflow">if</span> (result == PP_OK) {
...use file...
} <span class="keywordflow">else</span> {
...handle error...
}
}
</pre></div><p>As with regular completion callbacks, you can optionally add up to three bound arguments. These are passed following the output argument.</p>
<p>Your callback may take the output argument as a copy (common for small types like integers, a const reference (common for structures and resources to avoid an extra copy), or as a non-const reference. One optimization you can do if your callback function may take large arrays is to accept your output argument as a non-const reference and to swap() the argument with a vector of your own to store it. This means you don't have to copy the buffer to consume it. </p>
