Class::MethodMaker::OptExt(3p)

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.
