Bread::Board::LifeCyclUseriContributed PeBread::Board::LifeCycle::Singleton(3)

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.
