Bread::Board::LifeCycle::Singleton - service role for singleton lifecycle
version 0.34
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.
get
instance
The object build by the last call to get to actually do any work, and returned by any subsequent call to 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.
