public interface Behavior
The Behavior interface is the root API of the component behavior model. Behaviors are objects that
are attached to UIComponent
s in order to enhance components with functionality not explicitly defined by the
component implementation itself. The component behavior API is intended to support different types of behavior
contracts, and possibly different types of interactions between behaviors and components. The first such contract is
the ClientBehavior
, which defines a mechanism by which script-producing behaviors attach scripts to
components for execution on the client. In the future other types of behavior contracts may be added.
Like other attached objects (converters, validators) Behavior instances are created via the
Application
object. See
Application.createBehavior(java.lang.String)
for more details.
