Class::MethodMaker::OptExt(3)              User Contributed Perl Documentation


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.
