类 CmsValidationScheduler

java.lang.Object

org.opencms.gwt.client.validation.CmsValidationScheduler

public class CmsValidationScheduler
extends java.lang.Object

This is a helper class for scheduling form validations.

Since validations can be asynchronous, it would be possible for a validation to start while another one is still waiting for a response from the server if it were ran directly. This might result in an inconsistent state of the form fields being validated. To prevent this, validation controllers use this class to schedule validations, and call this class again after they're finished to execute the next validation.

The result of this is that a validation will only start after all unfinished validations which have been scheduled before it have finished running.
