25c1301a » mtodd 2008-03-09 Added Exceptions back into ... 2
3 # Included into Halcyon::Application in order to provide exception classes
4 # like NotModified, OK, Forbidden, or NotFound to simplify generating error
5 # methods and handling specific error instances.
6 #
7 # It is not intended for these exceptions to be destructive or process-ending
8 # in the least, only to simplify finishing up processing and relaying
9 # appropriate status to the caller/client.
10 #
11 # These classes inherit from StandardError because it is convenient to raise
12 # a given status and let Halcyon's dispatcher handle sending the message to
13 # the client, but it is possible to just instantiate an object without
14 # throwing an exception if necessary.
