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).
