103 | =head1 NAME |
104 | |
105 | Catalyst::Plugin::Authentication::User::Hash - An easy authentication user |
106 | object based on hashes. |
107 | |
108 | =head1 SYNOPSIS |
109 | |
110 | use Catalyst::Plugin::Authentication::User::Hash; |
111 | |
112 | Catalyst::Plugin::Authentication::User::Hash->new( |
113 | password => "s3cr3t", |
114 | ); |
115 | |
116 | =head1 DESCRIPTION |
117 | |
118 | This implementation of authentication user handles is supposed to go hand in |
119 | hand with L<Catalyst::Plugin::Authentication::Store::Minimal>. |
120 | |
121 | =head1 METHODS |
122 | |
123 | =over 4 |
124 | |
125 | =item new @pairs |
126 | |
127 | Create a new object with the key-value-pairs listed in the arg list. |
128 | |
129 | =item supports |
130 | |
131 | Checks for existence of keys that correspond with features. |
132 | |
133 | =item for_session |
134 | |
135 | Just returns $self, expecting it to be serializable. |
136 | |
137 | =item from_session |
138 | |
139 | Just passes returns the unserialized object, hoping it's intact. |
140 | |
141 | =item AUTOLOAD |
142 | |
143 | Accessor for the key whose name is the method. |
144 | |
