module ActionService # :nodoc:
# Action Service parameter specifiers may contain symbols or strings
# instead of Class objects, for a limited set of base types.
#
# This provides an unambiguous way to specify that a given parameter
# contains an integer or boolean value, for example.
#
# The allowed set of symbol/string aliases:
#
# [<tt>:int</tt>] any integer value
# [<tt>:float</tt>] any floating point value
# [<tt>:string</tt>] any string value
# [<tt>:bool</tt>] any boolean value
# [<tt>:time</tt>] any value containing both date and time
# [<tt>:date</tt>] any value containing only a date
