<static> prototype.scheduleTask

Schedule a task to be processed by the web worker asynchronously. If there are currently more tasks active than the maximum set by the constructor, will immediately return undefined. Otherwise, returns a promise that will resolve to the result posted back by the worker when finished.

Parameters:

Name	Type	Argument	Description
parameters	*		Any input data that will be posted to the worker.
transferableObjects	Array	<optional>	An array of objects contained in parameters that should be transferred to the worker instead of copied.

Returns:

Promise Either a promise that will resolve to the result when available, or undefined if there are too many active tasks,

Example

var taskProcessor = new Cesium.TaskProcessor('myWorkerName');
var promise = taskProcessor.scheduleTask({
    someParameter : true,
    another : 'hello'
});
if (!Cesium.defined(promise)) {
    // too many active tasks - try again later
} else {
    Cesium.when(promise, function(result) {
        // use the result of the task
    });
}
