These annotations allow a component to react to its own lifecycle events. They occur on methods of the component. There may be only one of each per component class.
@Create
@Create
Specifies that the method should be called when an instance of the component is instantiated by Seam. Note that create methods are only supported for JavaBeans and stateful session beans.
@Destroy
@Destroy
Specifies that the method should be called when the context ends and its context variables are destroyed. Note that create methods are only supported for JavaBeans and stateful session beans.
Note that all stateful session bean components must define a method annotated @Destroy @Remove in order to guarantee destruction of the stateful bean when a context ends.
Destroy methods should be used only for cleanup. Seam catches, logs and swallows any exception that propagates out of a destroy method.
@Observer
@Observer("somethingChanged")
Specifies that the method should be called when a component-driven event of the specified type occurs.
@Observer(value="somethingChanged",create=false)
Specifies that the method should be called when an event of the specified type occurs but that an instance should not be created if one doesn't exist. If an instance does not exist and create is false, the event will not be observed. The default value for create is true.
