man Class::MakeMethods::Docs::Catalog (3): List of Makable Method Types

DESCRIPTION

This document lists the various subclasses of Class::MakeMethods included in this distribution, and the method types each one provides.

See the documentation for each implementation for more details about the features it provides.

For each class, a parenthetical comment indicates whether the methods it generates are applicable to individual blessed objects (Instances), to class data (Global), or both (Any) =head2 Scoping

The final part of the name of a method-generating subclass typically indicates the scope or applicability of the methods it generates

Hash: For object instances based on blessed hashes with named values.
Array: For object instances based on blessed arrays with positional values.
Scalar: For object instances based on blessed scalars with a single value.
InsideOut: For any object instance regardless of underlying data type.
Ref: For any object instance regardless of underlying data type.
Inheritable: For data which can be set at the class, subclass, or instance level.
Class: For class data shared by all instances but different for each subclass
ClassVar: For class data shared by all instances but different for each subclass
ClassInherit: For class data shared by all instances but different for each subclass
Global: For global data shared by a class and all its instances and subclasses
PackageVar: For global data shared by a class and all its instances and subclasses
Universal: # General method types that are widely applicable

Template::PackageVar (Global)

PackageVar methods access a variable in the declaring package. Thus, they have the same effect as Static methods, while keeping their value accessible via the symbol table. See Class::MakeMethods::Template::PackageVar.

scalar: get and set a global scalar value
string: get and set a global string value
number: get and set a global number value

number: get and set a class-specific number value
boolean: get and set a class-specific boolean value
array: get and set values in a class-specific array

Template::ClassVar (Global)

ClassVar methods access a variable in the package on which they are called. Thus, they have the same effect as Class methods, while keeping their value accessible via the symbol table, like PackageVar. See Class::MakeMethods::Template::ClassVar.

scalar: get and set a class-specific scalar value
string: get and set a class-specific string value
number: get and set a class-specific number value
