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.
