Method Detail

executeEvent

public void executeEvent(PageLifecycleContext context,
                         java.lang.String event,
                         oracle.adf.model.OperationBinding actionBinding)

Description copied from class: PageLifecycle

Execute a single event.

Specified by:

executeEvent in class PageLifecycle

See Also:

handleEvent.

getEventMethod

public java.lang.reflect.Method getEventMethod(PageLifecycleContext context,
                                               java.lang.String eventName)

Description copied from class: PageLifecycle

Retrieve the Method class for a given an event name.

Parameters:

context - the PageLifecycle context

eventName - name of the event

Returns:

the Method object for this event if exist

invokeEventMethod

public boolean invokeEventMethod(PageLifecycleContext context,
                                 java.lang.String eventName)
                          throws java.lang.Exception

Description copied from class: PageLifecycle

Execute the Method class for a given an event name.

Parameters:

context - the PageLifecycle context

eventName - name of the event

Returns:

the Method object for this event if exist

Throws:

java.lang.Exception

invokeActionBinding

public boolean invokeActionBinding(PageLifecycleContext context,
                                   java.lang.String event)

Description copied from class: PageLifecycle

Invoke the action binding associated with the event name.

An action binding is associated with an event if an action binding with the same name as the event exist in the current binding container. If the action binding exist, the method parameters are initialized using the initializeMethodParameters method on the PageLifecycle before executing the action binding.

If the action binding exist the method return true

Parameters:

context - the lifecycle context

event - the name of the event

Returns:

true if an action binding is associated with the event

handleError

public void handleError(PageLifecycleContext context,
                        java.lang.Exception ex)

Description copied from class: PageLifecycle

Handles any exceptions that occurred during the PageLifecycle processing. Clients have an opportunity to merge the exception with the model errors stored in the BindingContainer.

Specified by:

handleError in class PageLifecycle

hasErrors

public boolean hasErrors(PageLifecycleContext context)

Description copied from class: PageLifecycle

Return true if an error occured during validation.

Specified by:

hasErrors in class PageLifecycle

initializeMethodParameters

public void initializeMethodParameters(PageLifecycleContext context,
                                       oracle.adf.model.OperationBinding actionBinding)

Description copied from class: PageLifecycle

This method is invoked before any ControlBinding or custom method is being executed. Overriding this method gives an opportunity to set the parameters.

Specified by:

initializeMethodParameters in class PageLifecycle

Parameters:

context - the PageLifecycle context

actionBinding - the action binding object to initialize

reportErrors

public void reportErrors(PageLifecycleContext context)

Description copied from class: PageLifecycle

Provide the opportunity to build an error list in a format appropriate to the view layer.

Specified by:

reportErrors in class PageLifecycle

findForward

public void findForward(PageLifecycleContext context)
                 throws java.lang.Exception

Description copied from class: PageLifecycle

The path of the next web page is identified using the forwardPath property on the PageLifecycleContext. If the redirect property on the PageLifecycleContext is true, the response will be redirected to the specified path. Otherwise, the request will be forwarded to the specified path.

Specified by:

findForward in class PageLifecycle

Throws:

java.lang.Exception

initContext

public void initContext(LifecycleContext context)

Description copied from class: Phases

During this phase the listener is able to initialize the LifecycleContext with additional information that will be persisted during the Lifecycle.

Specified by:

initContext in class Phases

prepareModel

public void prepareModel(LifecycleContext context)

Description copied from class: Phases

Give the opportunity for the data model to prepare and initialize.

Specified by:

prepareModel in class Phases

shouldAllowModelUpdate

public boolean shouldAllowModelUpdate(PageLifecycleContext context)

Description copied from class: PageLifecycle

This method is called during the processUpdateModel phase. It provides a way to programmatically by-pass model updates. The data model updates are disabled when specific action like 'rollback' will be executed during the lifecycle. This is done by calling the ignoreUpdates method or each action in the event list. The custom method ignoreUpdates is also called. Bypassing update might be necessary for operations such as rollback or custom methods that want to veto the change.
Overide this method if you need to add logic to skip data model updates.

Specified by:

shouldAllowModelUpdate in class PageLifecycle

See Also:

JUCtrlActionBinding.ignoreUpdates()

applyInputValues

public void applyInputValues(LifecycleContext context)

Description copied from class: Phases

Builds the list of events with their possible associated action binding from the request parameters.

Specified by:

applyInputValues in class Phases

validateInputValues

public void validateInputValues(LifecycleContext context)

Description copied from class: Phases

Validate input values.

Specified by:

validateInputValues in class Phases

processUpdateModel

public void processUpdateModel(LifecycleContext context)

Description copied from class: Phases

Update the data model with new and validated input values.

Specified by:

processUpdateModel in class Phases

validateModelUpdates

public void validateModelUpdates(LifecycleContext context)

Description copied from class: Phases

Forces model-level validation to occur.

Specified by:

validateModelUpdates in class Phases

processComponentEvents

public void processComponentEvents(LifecycleContext context)

Description copied from class: Phases

Process each event accumulated during the previous phases.

Specified by:

processComponentEvents in class Phases

metadataCommit

public void metadataCommit(LifecycleContext context)

Description copied from class: Phases

Used to commit Runtime changes to the metadata. This phase is always called before prepareRender even in case of navigation.

Specified by:

metadataCommit in class Phases

prepareRender

public void prepareRender(LifecycleContext context)

Description copied from class: Phases

Last phase before rendering a page. This can be used to notify a binding that rendering is about to happen and allow them to optimize data preparation or processing before the rendering begins.

During this phase the model is refreshed.

Specified by:

prepareRender in class Phases
