Functions

This API helps you run the JavaScript code on the main thread. It is an asynchronous API. It posts a message to the main thread to invoke a function f with parameters arguments.

NOTE: If runonMainThread is invoked in a JavaScript function that is already running on the main thread, then the function is executed in synchronous mode.

Syntax

kony.runOnMainThread (f, args);

Input Parameters

Parameters	Description
f [Function] - Mandatory	Specifies the callback function that must be executed.
args [Array] - Mandatory	Specifies the JavaScript array that holds the parameters to be passed to function f.

 

Example

kony.runOnMainThread(mainthread, []);
function mainthread () {
   kony.print ("Running on On Main Thread");
}

Return Values

None

Platform Availability

• Android
• iOS

Provides apps with multithreading capabilities.

Syntax

kony.runOnWorkerThread(f,args);

Input Parameters

Parameters	Description
f	Specifies the callback function that must be executed.
args	Specifies an array that holds the parameters to be passed to the function indicated by the f  parameter.

 

Example

kony.runOnWorkerThread(workermethod, []);
function workermethod () {
   kony.print ("Running on On Worker Thread");
}

Return Values

None.

Remarks

This function helps you run JavaScript code asynchronously on a worker thread. It posts a message to the worker thread that owns the current JavaScript context to invoke the function specified in the f parameter.

IMPORTANT: The assumption here is that main thread does not own any JavaScript context. The VM/closure thread and worker threads own the JavaScript context. When the kony.runOnWorkerThread is invoked from the main thread, a message is posted to the thread that originally invoked the kony.runOnMainThread. If the runonWorkerThread is invoked in a JavaScript function that is already running on the worker thread, then the function would be executed in synchronous mode.
