Method Detail

synchronizesVariablesWithBindings

public boolean synchronizesVariablesWithBindings()

Description copied from class: WOComponent

Indicates if the push-pull of values in the parent component is enabled. Returns whether a nested component pulls all values down from its parent and pushes all values to its parent before and after each phase of the request-response loop.

This method returns false for stateless components and true otherwise. Override this method to create a non-synchronizing, stateful component (return false ), or a synchronizing stateless component (return true).

Overrides:

synchronizesVariablesWithBindings in class WOComponent

Returns:

false if this method creates a non-synchronizing component, true otherwise

awake

public void awake()

Description copied from class: WOComponent

Invoked at the beginning of a WOComponent's involvement in a cycle of the request-response loop. It gives the WOComponent an opportunity to initialize its instance variables or perform setup operations. The default implementation does nothing.

Overrides:

awake in class WOComponent

WOComponent.ensureAwakeInContext(WOContext aContext), WOComponent.sleep()

nestingLevel

public int nestingLevel()

isExpanded

public boolean isExpanded()

nestingLevelForChildren

public int nestingLevelForChildren()

toggleExpansion

public WOComponent toggleExpansion()

hasChildren

public boolean hasChildren()

takeValuesFromRequest

public void takeValuesFromRequest(WORequest aRequest,
                                  WOContext aContext)

Description copied from class: WOComponent

Tells the component to synchronize its variables with values from the request. It is systematically called during the first phase of the component request handling. All WOComponent objects associated with a request are called with this method during the first phase of the request-response loop. The default WOComponent behavior is to invoke the method on the root WOElement object of the component's template (returned by template(). In this phase, each dynamic element in the template extracts any entered data or changed state (such as a check in a check box) associated with an attribute and assigns the value to the component variable bound to the attribute. Subclasses of WOComponent can override this method to replace or supplement the default behavior with custom logic.

Overrides:

takeValuesFromRequest in class WOComponent

Parameters:

aRequest - the current request with the WOComponent object

aContext - context of a transaction

See Also:

WOComponent.appendToResponse(WOResponse aResponse, WOContext aContext), WOComponent.invokeAction(WORequest aRequest, WOContext aContext)

invokeAction

public WOActionResults invokeAction(WORequest aRequest,
                                    WOContext aContext)

Description copied from class: WOComponent

Tells the component to execute any action specified in the request. It is systematically called during the middle phase of the component request handling. All WOComponent objects associated with a request page invoke this method. In this middle phase, the invokeAction method is propagated through the WOElement objects of the page. The dynamic element on which the user has acted (by, for example, clicking a button) responds by triggering the method in the request component that is bound to the action. WOComponent's default implementation of this method invokes invokeAction on the root WOElement object of the component template.

Overrides:

invokeAction in class WOComponent

Parameters:

aRequest - the request

aContext - context of the transaction

Returns:

a WOActionResults containing the result of the request

See Also:

WOComponent.appendToResponse(WOResponse aResponse, WOContext aContext), WOComponent.takeValuesFromRequest(WORequest aRequest, WOContext aContext)

appendToResponse

public void appendToResponse(WOResponse aResponse,
                             WOContext aContext)

Description copied from class: WOComponent

Forces the component to generate its interface and output it in the response's content. Component objects associated with a response receive this message during the last phase of the component request handling, or when returned by a direct action method. In the append-to-response phase, application objects (particularly the response page instance itself) generate the HTML content of the page. WOComponent's default implementation of this method invokes the appendToResponse method on the root WOElement object of the component template, which in turn invokes appendToResponse. Subclasses of WOComponent can override this method to replace or supplement the default behavior with custom logic.

Overrides:

appendToResponse in class WOComponent

Parameters:

aResponse - the HTTP response that an application returns to a Web server to complete a cycle of the request-response loop

aContext - context of a transaction
