NAME
       Bread::Board::LifeCycle::Singleton - service role for singleton lifecycle


VERSION
       version 0.37


DESCRIPTION
       Sub-role of Bread::Board::LifeCycle, this role defines the "singleton" lifecycle for a service. The "get"
       method will only do its work the first time it is invoked; subsequent invocations will return the same
       object.


ATTRIBUTES
   "instance"
       The object build by the last call to "get" to actually do any work, and returned by any subsequent call
       to "get".


METHODS
   "get"
       The first time this is called (or the first time after calling "flush_instance"), the actual "get" method
       will be invoked, and its return value cached in the "instance" attribute. The value of that attribute
       will always be returned, so you can call "get" as many time as you need, and always receive the same
       instance.

   "has_instance"
       Predicate for the "instance" attribute.

   "flush_instance"
       Clearer for the "instance" attribute. Clearing the attribute will cause the next call to "get" to
       instantiate a new object.
