NAME

       Class::MethodMaker::OptExt - Constants for C::MM's option extension mechanism

SYNOPSIS

       This class is internal to Class::MethodMaker and should not be used by any clients.  It is not part of the public API.

DESCRIPTION

       This class contains the constants used by Class::MethodMaker to determine the names of its methods dependent upon options invoked.

CLASS CONSTANTS

   OPTEXT
       OPTEXT is a map from options that are implemented as method extensions to the option parameters.

       Parameter keys are:

       encode
	   code number (to allow the option combination to be encoded whilst keeping the length of the subr name no more than 8 chars).  encode is
	   required for all opts (for determining method extension), and must be a power of two.

       refer
	   Code for referring to storage (default: '$_[0]->{$name}').

       decl
	   Code for declaring storage.

       postac
	   Code to execute immediately after any assignment check --- for example, to initialize storage if necessary

       asgnchk
	   Code for checking assignments.

       defchk
	   Code for default checking.

       reset
	   Code to execute when resetting an element

       read
	   Code to execute each time an value is read

       store
	   Code to execute each time a value is stored

CLASS COMPONENTS

CLASS HIGHER-LEVEL FUNCTIONS
   encode
       Take a set of options, return a two-letter code being the extension to add to the method to incorporate the extensions, and a list
       (arrayref) of the extensions represented.

       SYNOPSIS
	     my ($ext, $opt) =
	       Class::MethodMaker::OptExt->encode([qw( static type foobar )]);

       ARGUMENTS
	   options
	       The options to encode, as an arrayref of option names

       RETURNS
	   ext A code (string) to append to a methodname to represent the options used.

	   opts
	       The options represented by the ext .  This is generally a subset of the of those provided in options, for not all general options
	       are handled by an encoded methodname.
