Method Detail

action

protected void action(Path path,
                      InputData input,
                      OutputData output)
               throws Exception

If propagateAsAction(InputData) returns true then the action is propagated to the child. Otherwise if the request is the first one then:

• update(input)
• event(path, input)

are called on the child, if not then just render(output).

Overrides:

action in class BaseFilterWidget

Parameters:

path - The path of the component to whom the action is targeted.

input - The request data.

output - The response data.

Throws:

Exception - Any runtime exception that may occur.

getEventPath

protected Path getEventPath(InputData input)

Extracts the path from the input and returns it. This implementation uses the ApplicationWidget.EVENT_PATH_KEY parameter in the request and expects the event path to be a dot-separated string.

Since:

1.1

hasEvent

protected boolean hasEvent(InputData input)

Returns true if the request contains an event.

Since:

1.1

getActionPath

protected Path getActionPath(InputData input)

Extracts the path from the input and returns it. This implementation uses the ApplicationService.ACTION_PATH_KEY parameter in the request and expects the action path to be a dot-separated string.

Since:

1.1

hasAction

protected boolean hasAction(InputData input)

Returns true if the request contains an action.

Since:

1.1
