Bread::Board::LifeCycle::Singleton::WithParameters
version 0.33
Sub-role of the Bread::Board::LifeCycle manpage, this role defines the
``singleton'' lifecycle for a parameterized service. The get
method
will only do its work the first time it is invoked for each set of
parameters; subsequent invocations with the same parameters will
return the same object.
instances
Hashref mapping keys to objects, used to cache the results of get
get
Generates a key using generate_instance_key (passing it all the
arguments); if the instances attribute does not hold an object for
that key, it will build it (by calling the underlying get
method)
and store it in instances. The object (either retrieved from
instances or freshly built) will be returned.
generate_instance_key
Generates a (hopefully) unique key from the given arguments (usually, whatever was passed to get). The current implementation stringifies all arguments, so different references to identical values will be considered different.
