NAME

Bread::Board::LifeCycle::Singleton

VERSION

version 0.33

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.
