Class ResetService

java.lang.Object
  org.apache.tapestry.engine.AbstractService
      org.apache.tapestry.engine.ResetService

All Implemented Interfaces:

IEngineService

public class ResetService
extends AbstractService

ServiceLink used to discard all cached data (templates, specifications, et cetera). This is primarily used during development. It could be a weakness of a Tapestry application, making it susceptible to denial of service attacks, which is why it is disabled by default. The link generated by the ResetService redisplays the current page after discarding all data.

Since:

1.0.9
