Method Detail

initDCProperties

protected void initDCProperties(java.util.Map parameters)

beginRequest

public void beginRequest(java.util.HashMap map)

Description copied from class: DCDataControl

Invoked in some contexts to signal the beginning of a model request. For example, if the DataControl is referenced in a web application then this method will be invoked by the ADF framework before control is forwarded to the first Servlet defined by the request.

Subclassing datacontrols may extend this method to perform request level initialization of the DataControl.

This method is guaranteed to be called only once per browser request. Page forwards should not result in multiple invocations.

Specified by:

beginRequest in interface ManagedDataControl

Overrides:

beginRequest in class DCJboDataControl

Parameters:

map - a HashMap representing request context. Web applications which require request context may use the BindingContext.HTTP_REQUEST and BindingContext.HTTP_RESPONSE keys to acquire a reference from from the BindingContext.

findApplicationPool

protected ApplicationPool findApplicationPool(java.lang.String poolName,
                                              java.lang.String configPackage,
                                              java.lang.String configSection,
                                              java.util.Properties poolProps)

Overrides:

findApplicationPool in class DCJboDataControl

isOperationSupported

public boolean isOperationSupported(DCIteratorBinding iterBinding,
                                    byte oper)

Overrides to return true, for updates in case of placeholder datacontrol

Overrides:

isOperationSupported in class DCJboDataControl

Returns:

true for OPER_DATA_ROW_UPDATE

commitTransaction

public void commitTransaction()

Overrides to let user know that commit is not allowed in Placeholder dc

Overrides:

commitTransaction in class DCJboDataControl

rollbackTransaction

public void rollbackTransaction()

Overrides to let user know that commit is not allowed in Placeholder dc

Overrides:

rollbackTransaction in class DCJboDataControl

initializeJboSession

protected void initializeJboSession(java.lang.String configPackage,
                                    java.lang.String configName)

Overrides so that it can be called from the class in the same package.

Overrides:

initializeJboSession in class DCJboDataControl
