getCompatibilityScore
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 mappers for a mounted page, one mapped to
/foo
another to/foo/bar
and the incoming request URL is /foo/bar/baz, the mapping to/foo/bar
should probably 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 mapper does not recognize the request.
- Returns:
- the compatibility score, e.g. count of matching segments
-
canBeHandled
Checks whether the passed Url can be handled by this mapper- Parameters:
url
- the Url to check- Returns:
true
- if the Url can be handled,false
- otherwise
