createClientBehaviorContext

public static ClientBehaviorContext createClientBehaviorContext(FacesContext context,
                                                                UIComponent component,
                                                                java.lang.String eventName,
                                                                java.lang.String sourceId,
                                                                java.util.Collection<ClientBehaviorContext.Parameter> parameters)

Creates a ClientBehaviorContext instance.

Parameters:
context - the FacesContext for the current request.
component - the component instance to which the ClientBehavior is attached.
eventName - the name of the behavior event to which the ClientBehavior is attached.
sourceId - the id to use as the ClientBehavior's "source".
parameters - the collection of parameters for submitting ClientBehaviors to include in the request.
Returns:
a ClientBehaviorContext instance configured with the provided values.
Throws:
java.lang.NullPointerException - if context, component or eventName is null
Since:
2.0

getFacesContext

public abstract FacesContext getFacesContext()

Returns the FacesContext for the current request.

Since:
2.0

getComponent

public abstract UIComponent getComponent()

Returns the UIComponent that is requesting the ClientBehavior script.

Since:
2.0

getEventName

public abstract java.lang.String getEventName()

Returns the name of the behavior event for which the ClientBehavior script is being requested.

Since:
2.0

getSourceId

public abstract java.lang.String getSourceId()

Returns an id for use as the ClientBehavior source. ClientBehavior implementations that submit back to the Faces lifecycle are required to identify which component triggered the ClientBehavior-initiated request via the javax.faces.source request parameter. In most cases, th source id can be trivially derived from the element to which the behavior's client-side script is attached - ie. the source id is typically the id of this element. However, in components which produce more complex content, the behavior script may not be able to determine the correct id to use for the javax.faces.source value. The ClientBehaviorContext#getSourceId method allows the component to pass this information into the ClientBehavior#getScript implementation.

Returns:
the id for the behavior's script to use as the "source", or null if the Behavior's script can identify the source from the DOM.
Since:
2.0

getParameters

public abstract java.util.Collection<ClientBehaviorContext.Parameter> getParameters()

Returns parameters that "submitting" ClientBehavior implementations should include when posting back data into the Faces lifecycle. If no parameters are specified, this method returns an empty (non-null) collection.

Since:
2.0
