111 | =head1 NAME |
112 | |
e522431d |
113 | Moose::Object - The base object for Moose |
fcd84ca9 |
114 | |
fcd84ca9 |
115 | =head1 DESCRIPTION |
116 | |
6ba6d68c |
117 | This serves as the base object for all Moose classes. Every |
118 | effort will be made to ensure that all classes which C<use Moose> |
119 | will inherit from this class. It provides a default constructor |
120 | and destructor, which run all the BUILD and DEMOLISH methods in |
121 | the class tree. |
122 | |
123 | You don't actually I<need> to inherit from this in order to |
124 | use Moose though. It is just here to make life easier. |
125 | |
fcd84ca9 |
126 | =head1 METHODS |
127 | |
128 | =over 4 |
129 | |
130 | =item B<meta> |
131 | |
6ba6d68c |
132 | This will return the metaclass associated with the given class. |
133 | |
fcd84ca9 |
134 | =item B<new> |
135 | |
e606ae5f |
136 | This will call C<BUILDARGS>, create a new instance and call C<BUILDALL>. |
137 | |
138 | =item B<BUILDARGS> |
139 | |
140 | This method processes an argument list into a hash reference. It is used by |
141 | C<new>. |
e522431d |
142 | |
c0e30cf5 |
143 | =item B<BUILDALL> |
144 | |
d7f17ebb |
145 | This will call every C<BUILD> method in the inheritance hierarchy, |
146 | and pass it a hash-ref of the the C<%params> passed to C<new>. |
e522431d |
147 | |
c0e30cf5 |
148 | =item B<DEMOLISHALL> |
149 | |
e522431d |
150 | This will call every C<DEMOLISH> method in the inheritance hierarchy. |
151 | |
ef333f17 |
152 | =item B<does ($role_name)> |
153 | |
02a0fb52 |
154 | This will check if the invocant's class C<does> a given C<$role_name>. |
155 | This is similar to C<isa> for object, but it checks the roles instead. |
156 | |
e606ae5f |
157 | =item B<DOES ($class_or_role_name)> |
158 | |
159 | A Moose Role aware implementation of L<UNIVERSAL/DOES>. |
160 | |
161 | C<DOES> is equivalent to C<isa> or C<does>. |
162 | |
f742dfef |
163 | =item B<dump ($maxdepth)> |
164 | |
6549b0d1 |
165 | C'mon, how many times have you written the following code while debugging: |
f742dfef |
166 | |
167 | use Data::Dumper; |
168 | warn Dumper $obj; |
169 | |
170 | It can get seriously annoying, so why not just use this. |
