Method Detail

beginExecute

public void beginExecute(javax.faces.context.ExternalContext ec,
                         Serializable[] params)

Description copied from class: TaskHandler

Run at the begin of an execution so that the environment may be set up correctly. Handler's overriding this method "should not" execute the superclass logic as it will impact the default logic of the endExecute method.

Overrides:

beginExecute in class TaskHandler

Parameters:

ec - The external context

params - Array of serializable parameters

beginExecute

public void beginExecute(javax.faces.context.ExternalContext ec,
                         Map<K,V> map)

endExecute

public Serializable endExecute(javax.faces.context.ExternalContext ec,
                               Serializable[] params)

Description copied from class: TaskHandler

Run at the end of an execution so that a result may be returned and the environment can be cleaned up properly.

Overrides:

endExecute in class TaskHandler

Parameters:

ec - The external context

params - Array of serializable parameters

Returns:

Any exception thrown serialized.

endExecute

public Serializable endExecute(javax.faces.context.ExternalContext ec,
                               Map<K,V> map)

invoke

public Serializable invoke(javax.faces.context.ExternalContext ec,
                           Serializable[] params)

Description copied from class: TaskHandler

Run durring an invoke request.

Overrides:

invoke in class TaskHandler

Parameters:

ec - The external context.

params - Array of serializable parameters

Returns:

Any exception thrown serialized.

invoke

public Serializable invoke(javax.faces.context.ExternalContext ec,
                           Map<K,V> map)

validateExecution

public Serializable validateExecution(javax.faces.context.ExternalContext ec,
                                      Serializable[] params)

Description copied from class: TaskHandler

Run before the beginExecute or the invoke methods in a request. Generally this method will not be overridden, but it essentially allows for validation of the environment before execution continues. If a result other then "null" is returned, then the current request will return immedietly without executing the faces lifecycle or any other task handlers and a FAILED_VALIDATION response will be returned to the server with this return value as the result.

If the returned object is an exception, it will be added to the logs. If it is any other type of object it will be

Overrides:

validateExecution in class TaskHandler

Parameters:

ec - The External Context.

params - Array of serializable parameters.

Returns:

Any exception thrown serialized.

validateExecution

public Serializable validateExecution(javax.faces.context.ExternalContext ec,
                                      Map<K,V> map)
