IActiveScriptProfilerCallback Interface
Provides methods that are used by the scripting engine to notify a profiler object when events occur. This interface is implemented by the profiler object.
Methods
| Method | Description |
|---|---|
| IActiveScriptProfilerCallback::Initialize | Called to initialize the profiler object whenever profiling is started on a scripting engine. |
| IActiveScriptProfilerCallback::Shutdown | Called to free and release the profiler object whenever profiling is stopped on a scripting engine. |
| IActiveScriptProfilerCallback::ScriptCompiled | Notifies the profiler object that the scripting engine compiled the script. |
| IActiveScriptProfilerCallback::FunctionCompiled | Notifies the profiler object that the scripting engine encountered a function when compiling a script. |
| IActiveScriptProfilerCallback::OnFunctionEnter | Notifies the profiler object that the scripting engine is about to execute a function call that is not a call into the Document Object Model (DOM). |
| IActiveScriptProfilerCallback::OnFunctionExit | Notifies the profiler object that the scripting engine finished executing a function call that is not a call into the DOM. |
Remarks
Notification of function calls into the Document Object Model (DOM) is provided by the IActiveScriptProfilerCallback2 Interface.
Note
To add the ability to start and stop profiling when a script is running, call the following methods. By using these methods, you can obtain the complete call stack if JavaScript is running when you start or stop profiling.
- Call IActiveScriptProfilerControl2::CompleteProfilerStart to notify the profiler that you have started profiling.
- Call IActiveScriptProfilerControl2::PrepareProfilerStop to notify the profiler that you will soon stop profiling.
