module ActionDispatch

# This is a class that abstracts away an asserted response.
|
||
|
|
# It purposely does not inherit from Response, because it doesn't need it.
|
||
|
|
# That means it does not have headers or a body.
|
||
|
|
#
|
||
|
|
# As an input to the initializer, we take a Fixnum, a String, or a Symbol.
|
||
|
|
# If it's a Fixnum or String, we figure out what its symbolized name.
|
||
|
|
# If it's a Symbol, we figure out what its corresponding code is.
|
||
|
|
# The resulting code will be a Fixnum, for real HTTP codes, and it will
|
||
|
|
# be a String for the pseudo-HTTP codes, such as:
|
||
|
|
# :success, :missing, :redirect and :error
