Interface DataControlFactory

All Known Implementing Classes:

DataControlFactoryImpl, DataControlFactoryImpl, DataControlFactoryImpl, DataControlFactoryImpl, DataControlFactoryImpl, DataControlFactoryImpl

public interface DataControlFactory

Field Summary

static java.lang.String	APP_PARAM_COOKIE_PROPERTIES Deprecated. use APP_PARAM_REQUEST_CONTEXT instead.
static java.lang.String	APP_PARAM_ENV_INFO
static java.lang.String	APP_PARAM_HTTP_SESSION Deprecated. the HttpSession will no longer be passed as an application parameter from the ADFBindingFilter. DataControls that must access the HttpSession should use: ((HttpServletRequest)ADFContext.getCurrent().getEnvironment().getRequest()).getSession(true) or: ADFContext.getCurrent().getSessionScope().get(String) instead.

Method Summary

DataControl	createSession(BindingContext ctx, Node node, java.util.Map applicationParams) The DataControl developer should implement createSession to return an instance of DataControl.
DataControl	createSession(BindingContext ctx, java.lang.String sName, java.util.Map applicationParams, java.util.Map cpxMetaData) The DataControl developer should implement createSession to return an instance of DataControl.

Method Detail

createSession

DataControl createSession(BindingContext ctx,
                          Node node,
                          java.util.Map applicationParams)

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.

Parameters:

ctx - The BindingContext for which the DataControl is being created

node - The DOM node of the DataControl definition that is being created

applicationParams - Additional application createSession context

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.

createSession

DataControl createSession(BindingContext ctx,
                          java.lang.String sName,
                          java.util.Map applicationParams,
                          java.util.Map cpxMetaData)

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.

Parameters:

ctx - The BindingContext for which the DataControl is being created

sName - The DataControl name as specified in the DataControl definition

applicationParams - Additional application createSession context

cpxMetaData - 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.
