Interface IAjaxIndicatorAware
- All Superinterfaces:
IClusterable
,Serializable
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
This interface makes it trivial to use busy indicators for ajax requests. This interface can be
implemented by a component that has an ajax behavior attached to it, or any parent of the
component, or by the ajax behavior itself. If this is the case javascript will be added
automatically that will show a markup element pointed to by the
getAjaxIndicatorMarkupId()
markup id attribute when the ajax request begins, and hide it
when the ajax requests succeeds or fails.
If both a component and a behavior implement this interface, the component will take precedence.
