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.
