Library: JS/Core
Package: Execution
Header: Poco/JS/Core/JSExecutor.h
Description
This class extends the basic JSExecutor class with a JSTimer-based event loop, allowing the definition of timers in JavaScript code.
Scripts can use the setTimeout() and setInterval() JavaScript functions to define timer-based callbacks.
Inheritance

Constructors
TimedJSExecutor
TimedJSExecutor(
const std::string & source,
const Poco::URI & sourceURI,
const std::vector < std::string > & moduleSearchPaths,
Poco::UInt64 memoryLimit = JSExecutor::DEFAULT_MEMORY_LIMIT
);
Creates the TimedJSExecutor.
Destructor
~TimedJSExecutor 
~TimedJSExecutor();
Destroys the TimedJSExecutor.
Member Functions
run
void run();
Runs the script as timer task. Note that run() will return immediately. The script will be executed within the timer thread.

schedule
void schedule(
Poco::Util::TimerTask::Ptr pTask
);
Schedules a task using the timer-based event loop.
schedule
void schedule(
Poco::Util::TimerTask::Ptr pTask,
const Poco::Clock & clock
);
Schedules a task using the timer-based event loop.
stop
void stop();
Stops the executor and cancels all timer events.
