DESCRIPTION

70       Log::Dispatch role for use with your Moose classes.
71

INTERFACE

73   logger
74       This method is provided by this role, and it is an Log::Dispatch
75       instance, which you can call level-names on, as in the debug examples
76       in the synopsis.
77
78       If you want the level-names as direct methods in your class, you should
79       use the MooseX::LazyLogDispatch::Levels role instead.
80
81   log_dispatch_config
82       This is an optional attribute you can give to your class.  If you
83       define it as a hashref value, that will be interpreted in the style of
84       the configuration hashrefs documented in Log::Dispatch::Config
85       documents when they show examples of using Log::Dispatch::Configurator
86       for pluggable configuration.
87
88       You can also gain greater flexibility by defining your own complete
89       Log::Dispatch::Configurator subclass and having your
90       "log_dispatch_config" attribute be an instance of this class.
91
92       By lazy-loading either one ("lazy =" 1>), you can have the
93       configuration determined at runtime.  This is nice if you want to
94       change your log format and/or destination at runtime based on things
95       like MooseX::Getopt / MooseX::Daemonize parameters.
96
97       If you don't provide this attribute, we'll default to sending
98       everything to the screen in a reasonable debugging format.
