NAME ^

Class::Dot::Object - The default base object for Class::Dot classes.

VERSION ^

This document describes Class::Dot version 2.0.0_15

DESCRIPTION ^

This is the default base class for Class::Dot classes. You don't have to inherit from this class manually, it is done automaticly when you import Class::Dot in your class.

Actually it is a bit more complex than that, it is the base class for Class::Dot's default metaclass, Class::Dot::Meta::Class. You can extend it's functionality by subclassing Class::Dot::Meta::Class and then set that subclass as the metaclass with the -metaclass option, via there you can decide which base class you want.

This class contain useful methods for introspection on your class's attributes, metaclass and so on.

Notice how this base class has no constructor or destructor, these are built dynamicly by the metaclass.

SUBROUTINES/METHODS ^

INSTANCE METHODS

__hasattr__($attribute_name)

Returns true if the class has the attribute $attribute_name.

__getattr__($attribute_name)

Get the value of an attribute.

__setattr__($attribute_name, $value)

Set the value of an attribute.

NOTE This will not check if the value conforms to the type constraint even if the -constrained option is set. To do this dynamically you have to do it like this:

     my $set_attr = $self->__meta__($attribute)->setter_name();
     $self->$set_attr($value);

__meta__($attribute_name)

Return attribute metadata for an attribute by it's name. This will return the attribute's type instance. See Class::Dot::Type for the methods available.

__metaclass__()

Return the instance of the metaclass for this class.

__is_finalized__()

Returns true if this class is finalized.

__finalize__()

Finalize the class.
