What is a View Handler?

View handlers are Java classes that contain the logic necessary to create a view and perform actions specified by setting attributes of the view. View handlers also can include information for the convenience of interactive forms. When a view is checked in, the view handler reads the view attributes and converts them into operations on repository objects. The view handler will often launch a workflow to perform more complex tasks such as approvals or provisioning. Most view handlers that operate on users prevent you from checking in the view if there is already a workflow in progress for that user.
