Method Detail

getCompatibilityScore

public int getCompatibilityScore(Request request)
Description copied from interface: IRequestMapper
Returns the score representing how compatible this request mapper is to processing the given request. When a request comes in all mappers are scored and are tried in order from highest score to lowest.

A good criteria for calculating the score is the number of matched url segments. For example when there are two encoders for mounted page, one mapped to /foo another to /foo/bar and the incoming request URL is /foo/bar/baz, the encoder mapped to /foo/bar will handle the request first as it has matching segments count of 2 while the first one has only matching segments count of 1.

Note that the method can return value greater then zero even if the encoder can not decode the request.

Specified by:
getCompatibilityScore in interface IRequestMapper
Returns:
count of matching segments

mapHandler

public Url mapHandler(IRequestHandler requestHandler)
Description copied from interface: IRequestMapper
Returns the Url for given IRequestHandler or null if the encoder does not recognize the request handler.

Specified by:
mapHandler in interface IRequestMapper
Returns:
Url instance or null.

mapRequest

public IRequestHandler mapRequest(Request request)
Description copied from interface: IRequestMapper
Returns IRequestHandler for the request or null if the encoder does not recognize the URL.

Specified by:
mapRequest in interface IRequestMapper
Parameters:
request - provides access to request data (i.e. Url and Parameters)
Returns:
RequestHandler instance or null
