Method Detail

colCount

public int colCount()

isStateless

public boolean isStateless()

Description copied from class: WOComponent

By default, this method returns false, indicating that state will be maintained for instances of the receiver. Overriding this method to return true will make the component stateless. A single instance of each stateless component is shared between multiple sessions, reducing the application's memory footprint.

By default, stateless components don't synchronize. So, if you override this method to return true and you want the component to synchronize, you must also override synchronizesVariablesWithBindings and return true.

Overrides:

isStateless in class WOComponent

Returns:

true if this method is overidden, false otherwise

list

public NSArray list()

maxColumns

public int maxColumns()

pushItem

public void pushItem()

reset

public void reset()

Description copied from class: WOComponent

Allows a stateless component to reset temporary references. This method -- which is only invoked if the component is stateless -- allows a component instance to reset or delete temporary references to objects that are specific to a given context. To ensure that when the shared instance of a component is reused by another session there are no side effects, implement this method so that it releases and sets to null each of the component's instance variables.

Overrides:

reset in class WOComponent

WOComponent.isStateless()

rowCount

public int rowCount()

setCurrentCol

public void setCurrentCol(Number newValue)

setCurrentRow

public void setCurrentRow(Number newValue)

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
