Bread::Board::LifeCycle::Singleton
version 0.33
Sub-role of the Bread::Board::LifeCycle manpage, 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.
instance
The object build by the last call to get
to actually do any work,
and returned by any subsequent call to get
.
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.
