CustomerInfoFormAPI()
The
CustomerInfoFormAPI() function is the constructor for the class. It calls the super()
method to initialize the Form super class. It also calls the
NetDebug.initialize() method to
initialize Flash Remoting debug support and sets the
initialized variable to false to indicate
to later code that initialization has not been completed. Then it calls the constructor for the
Service object to create a reference (
custService), to the customerData service. The constructor
submits an empty string for the
gatewayUrl parameter because the gateway connection is
established by the following
flashvars parameter in the CustomerInfoExampleAPI.html file,
which you open to run the application:
<param name="flashvars" value="gatewayUrl=http://localhost:8300/flashservices/
gateway/"/>
