Class ResetService

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

All Implemented Interfaces:

IEngineService

public class ResetService
extends Object
implements IEngineService

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

Method Detail

getLink

public ILink getLink(boolean post,
                     Object parameter)

Description copied from interface: IEngineService

Builds a URL for a service. This is performed during the rendering phase of one request cycle and builds URLs that will invoke activity in a subsequent request cycle.

This method changed incompatibly between release 3.0 and release 4.0.

Specified by:

getLink in interface IEngineService

Parameters:

post - if true, then the link will be used for a post (not a get, i.e., for a HTML form); this may affect what information is encoded into the link

parameter - An object that provide any additional information needed by the service. Each service implementation will expect that an object of the proper type be passed in. In some cases, a simple String will do; in others, a specific object (possibly implementing an interface) will be required.

Returns:

The URL for the service. The URL will have to be encoded via HttpServletResponse.encodeURL(java.lang.String).

getName

public String getName()
