/* The uri dispatcher is responsible for taking uri's, determining
|
|
the content and routing the opened url to the correct content
|
|
handler.
|
|
|
|
When you encounter a url you want to open, you typically call
|
|
openURI, passing it the content listener for the window the uri is
|
|
originating from. The uri dispatcher opens the url to discover the
|
|
content type. It then gives the content listener first crack at
|
|
handling the content. If it doesn't want it, the dispatcher tries
|
|
to hand it off one of the registered content listeners. This allows
|
|
running applications the chance to jump in and handle the content.
|
|
|
|
If that also fails, then the uri dispatcher goes to the registry
|
|
looking for the preferred content handler for the content type
|
|
of the uri. The content handler may create an app instance
|
|
or it may hand the contents off to a platform specific plugin
|
|
or helper app. Or it may hand the url off to an OS registered
|
|
application.
