Class::Scaffold::Accessor - Construct framework-specific accessors

VERSION

Top

version 1.100760

METHODS

Top

mk_framework_object_accessors

Makes factory-typed accessors - see Class::Accessor::FactoryTyped - and uses Class::Scaffold::Factory::Type as the factory class.

mk_framework_object_array_accessors

Makes factory-typed array accessors - see Class::Accessor::FactoryTyped - and uses Class::Scaffold::Factory::Type as the factory class.

mk_readonly_accessors

Takes an array of strings as its argument. For each string it creates methods as described below, where * denotes the slot name.

*

This method can retrieve a value from its slot. If it receives an argument, it throws an exception. If called without a value, the method retrieves the value from the slot. There is a method to set the value - see below -, but separating the setter and getter methods ensures that it can't be set, for example, using the class' constructor.

*_set, set_*

Sets the slot to the given value and returns it.
