bapi code

Hi All,

I am new to this webdynpro for java code. I have 2 bapi's. Can anyone explain me what this code does.

public void wdDoInit()

{

//@@begin wdDoInit()

//Create a new element in node

//Bapi_Flbooking_Createfromdata_Input

Bapi_Flbooking_Createfromdata_Input input =new Bapi_Flbooking_Createfromdata_Input();

wdContext.nodeBapi_Flbooking_Createfromdata_Input().bind(input);

//Create a new element in node Booking_Data

input.setBooking_Data(new Bapisbonew()); (explain this particular line also)

//Create a new element in node

//Bapi_Flight_Checkavailibility_Input

Bapi_Flight_Checkavailibility_Input inputAvailibility =

new Bapi_Flight_Checkavailibility_Input();

wdContext.nodeBapi_Flight_Checkavailibility_Input().bind(inputAvailibility);

Regards,
