Method Detail


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.

isStateless in class WOComponent
true if this method is overidden, false otherwise

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.
