public Interface Behavior

Known Direct Subinterfaces
javax.faces.component.behavior.ClientBehavior
Known Direct Implementers
javax.faces.component.behavior.BehaviorBase
Imports
javax.faces.component.UIComponent, javax.faces.event.BehaviorEvent

The Behavior interface is the root API of the component behavior model. Behaviors are objects that are attached to UIComponents 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 javax.faces.application.Application object. See javax.faces.application.Application#createBehavior for more details.
