120 | =head1 NAME |
121 | |
e522431d |
122 | Moose::Object - The base object for Moose |
fcd84ca9 |
123 | |
fcd84ca9 |
124 | =head1 DESCRIPTION |
125 | |
6ba6d68c |
126 | This serves as the base object for all Moose classes. Every |
127 | effort will be made to ensure that all classes which C<use Moose> |
128 | will inherit from this class. It provides a default constructor |
129 | and destructor, which run all the BUILD and DEMOLISH methods in |
130 | the class tree. |
131 | |
132 | You don't actually I<need> to inherit from this in order to |
133 | use Moose though. It is just here to make life easier. |
134 | |
fcd84ca9 |
135 | =head1 METHODS |
136 | |
137 | =over 4 |
138 | |
139 | =item B<meta> |
140 | |
6ba6d68c |
141 | This will return the metaclass associated with the given class. |
142 | |
fcd84ca9 |
143 | =item B<new> |
144 | |
7bec196c |
145 | This will call C<BUILDARGS>, create a new instance and call C<BUILDALL>. |
146 | |
147 | =item B<BUILDARGS> |
148 | |
149 | This method processes an argument list into a hash reference. It is used by |
150 | C<new>. |
e522431d |
151 | |
c0e30cf5 |
152 | =item B<BUILDALL> |
153 | |
d7f17ebb |
154 | This will call every C<BUILD> method in the inheritance hierarchy, |
155 | and pass it a hash-ref of the the C<%params> passed to C<new>. |
e522431d |
156 | |
c0e30cf5 |
157 | =item B<DEMOLISHALL> |
158 | |
e522431d |
159 | This will call every C<DEMOLISH> method in the inheritance hierarchy. |
160 | |
ef333f17 |
161 | =item B<does ($role_name)> |
162 | |
02a0fb52 |
163 | This will check if the invocant's class C<does> a given C<$role_name>. |
164 | This is similar to C<isa> for object, but it checks the roles instead. |
165 | |
d0e9d54e |
166 | =item B<DOES ($class_or_role_name)> |
167 | |
168 | A Moose Role aware implementation of L<UNIVERSAL/DOES>. |
169 | |
170 | C<DOES> is equivalent to C<isa> or C<does>. |
171 | |
f742dfef |
172 | =item B<dump ($maxdepth)> |
173 | |
174 | Cmon, how many times have you written the following code while debugging: |
175 | |
176 | use Data::Dumper; |
177 | warn Dumper $obj; |
178 | |
179 | It can get seriously annoying, so why not just use this. |
