Class::MakeMethods::Standard - Make common object accessors

    hash => 'my_index',


This document describes the various subclasses of Class::MakeMethods included under the Standard::* namespace, and the method types each one provides.

The Standard subclasses provide a parameterized set of method-generation implementations.

Subroutines are generated as closures bound to a hash containing the method name and (optionally) additional parameters.

Calling Conventions

When you use a subclass of this package, the method declarations you provide as arguments cause subroutines to be generated and installed in your module. You can also omit the arguments to use and instead make methods at runtime by passing the declarations to a subsequent call to make().

You may include any number of declarations in each call to use or make(). If methods with the same name already exist, earlier calls to use or make() win over later ones, but within each call, later declarations superceed earlier ones.

You can install methods in a different package by passing -target_class => package as your first arguments to use or make.

See "USAGE" in Class::MakeMethods for more details.

Declaration Syntax

The following types of Simple declarations are supported:

  • generator_type => 'method_name'

  • generator_type => 'name_1 name_2...'

  • generator_type => [ 'name_1', 'name_2', ...]

For a list of the supported values of generator_type, see "STANDARD CLASSES" in Class::MakeMethods::Docs::Catalog, or the documentation for each subclass.

For each method name you provide, a subroutine of the indicated type will be generated and installed under that name in your module.

Method names should start with a letter, followed by zero or more letters, numbers, or underscores.

Parameter Syntax

The Standard syntax also provides several ways to optionally associate a hash of additional parameters with a given method name.

  • generator_type => [ 'name_1' => { param=>value... }, ... ]

    A hash of parameters to use just for this method name.

    (Note: to prevent confusion with self-contained definition hashes, described below, parameter hashes following a method name must not contain the key 'name'.)

  • generator_type => [ [ 'name_1', 'name_2', ... ] => { param=>value... } ]

    Each of these method names gets a copy of the same set of parameters.

  • generator_type => [ { 'name'=>'name_1', param=>value... }, ... ]

    By including the reserved parameter 'name', you create a self-contained declaration with that name and any associated hash values.

Simple declarations, as shown in the prior section, are treated as if they had an empty parameter hash.
