Class: Processing

Monster .Util. Processing

This class allows to execute several functions in order.

Functions and timeouts can be passed. If a timeout is passed, it applies to all further functions. In the example

timeout1, function1, function2, function3, timeout2, function4

the timeout1 is valid for the functions 1, 2 and 3 and the timeout2 for the function4.

So the execution time is timeout1+timeout1+timeout1+timeout2

The result of run() is a promise.

Constructor

new Processing(timeout, callback)

Class to be able to execute function chains

Create new Processing

Functions and timeouts can be passed. If a timeout is passed, it applies to all further functions. In the example

timeout1, function1, function2, function3, timeout2, function4

the timeout1 is valid for the functions 1, 2 and 3 and the timeout2 for the function4.

So the execution time is timeout1+timeout1+timeout1+timeout2

Parameters:

Name	Type	Description
