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

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

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.
