NAME

       Jifty::Param - Parameters for Jifty actions

DESCRIPTION

       Describes a parameter to a "Jifty::Action" object.  Do not construct this by hand -- use Jifty::Param::Schema in the action package to
       declare parameters instead.

   accessors
       Although this class is not derived from Jifty::Web::Form::Field, it does share the accessors from it; see Jifty::Web::Form::Field, for the
       list of possible keys that each parameter can have.

       In addition to the list there, you may use these additional keys:

       constructor
	   A boolean which, if set, indicates that the argument must be present in the "arguments" passed to create the action, rather than being
	   expected to be set later.

	   Defaults to false.

       valid_values
	   An array reference.	Each element should be either:

	   o   A hash reference with a "display" field for the string to display for the value, and a "value" field for the value to actually send
	       to the server.

	   o   A hash reference with a "collection" field containing a Jifty::Collection, and "display_from" and "value_from" fields containing
	       the names of methods to call on each record in the collection to get "display" and "value".

	   o   A simple string, which is treated as both "display" and "value".

       available_values
	   Just like valid_values, but represents the list of suggested values, instead of the list of acceptable values.

       sort_order
	   An integer of how the parameter sorts relative to other parameters.	This is usually implicitly generated by its declaration order.

   new
       Creates a new Jifty::Param object.  Note that unlike Jifty::Web::Form::Field, the object is never magically reblessed into a subclass.
       Should only be called implicitly from a Jifty::Param::Schema declaration.
