NAME¶
Class::MethodMaker::OptExt - Constants for C::MM's option extension mechanismSYNOPSIS¶
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.
