StatefulController Class Reference

This Controller class encapsulates the implementation logic for IStateHandler registration and toggle event listening. A customization example:

class MyStateHandlerClass extends PDFViewCtrl.IStateHandler {
 // ... 
}
class MyStateController extends UIExtension.controllers.StatefulController {
 constructor(component) {
     super(component, MyStateHandlerClass);
 }
}

Detailed Description

This Controller class encapsulates the implementation logic for IStateHandler registration and toggle event listening. A customization example:

class MyStateHandlerClass extends PDFViewCtrl.IStateHandler {
 // ... 
}
class MyStateController extends UIExtension.controllers.StatefulController {
 constructor(component) {
     super(component, MyStateHandlerClass);
 }
}

Classes inherit from StatefulController must override this contructor and passing a class inherit from IStateHandler into super() function. If that StateHandler class has been registed, you can also passing the state handler name instead of class into super() function.

Example 1, passing a MyStateHandlerClass into super():

class MyStateHandlerClass extends PDFViewCtrl.IStateHandler {
 // ... 
}
class MyStateController extends UIExtension.controllers.StatefulController {
 constructor(component) {
     super(component, MyStateHandlerClass);
 }
}

Example 2, passing state handler name into super():

class MystateController extends UIExtension.controllers.StatefulController {
 constructor(component) {
 super(component, 'your-custom-state-name');
}
}

Parameters

component	Component -
ExpectedStateHandlerClass	string|(new()=>IStateHandler) -
