Creating State Adaptation plug-in

Required background

Before you start, you must know:

• First ordinal: used to identify an item in an ordered set.

• An understanding on System State Manager (SSM).

Introduction

This is an SPI, MStateAdaptation, which allows customization of the functionality of SSM adaptation interface. The SSM adaptation server creates MStateAdaptation class by calling the first ordinal in the DLL that is susstateadaptation.dll.

The function prototype of the first ordinal is MStateAdaptation * CreateCExampleStateAdaptation();

Follow the procedure given below to create a state adaptation plug-in:

Procedure

1. Define a class from MStateAdaptation interface.

2. Export the static method to create new state adaptation plug-in as shown in the code snippet:

   
   EXPORT_C MStateAdaptation* CreateStateAdaptationL()
   {
       CStateAdaptation* stateAdaptation = CStateAdaptation::NewL();
       return ( static_cast<MStateAdaptation*>(stateAdaptation ));
   }
   

   The code returns a new plugin object for state adaptation.

Results

The state adaptation plug-in is created.
