Bread::Board::LifeCyclUserrContributed:PerlCDocumentagleton::WithParameters(3)

NAME
       Bread::Board::LifeCycle::Singleton::WithParameters - singleton
       lifecycle role for a parameterized service

VERSION
       version 0.37

DESCRIPTION
       Sub-role	of Bread::Board::LifeCycle, 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.

ATTRIBUTES
   "instances"
       Hashref mapping keys to objects,	used to	cache the results of "get"

METHODS
   "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.
