Description copied from interface: DataControlFactory

The DataControl developer should implement createSession to return an instance of DataControl. For example, the JavaBean DataControl implements DataControlFactoryImpl to return an instance of DCGenericDataControl.

The data binding framework will typically invoke this method once, at the beginning of a new application session. The DataControl factory implementation to use is determined by the DataControl definition.

Specified by:

createSession in interface DataControlFactory

Overrides:

createSession in class DataControlFactoryImpl

Parameters:

ctx - The BindingContext for which the DataControl is being created

sName - The DataControl name as specified in the DataControl definition

appParams - Additional application createSession context

parameters - A Map containing name/value pairs of the properties defined in the DataControl definition

The framework may pass additional context in the applicationParams Map. For example, in the case of a HttpSession, the framework will add the current HttpSession to the applicationParams Map.
