INTEGRATES This package integrates behaviors from: Data::Object::Role::Buildable Data::Object::Role::Proxyable Data::Object::Role::Stashable LIBRARIES This package uses type constraints from: Types::Standard ATTRIBUTES This package has the following attributes: named named(HashRef) This attribute is read-only, accepts (HashRef) values, and is optional. METHODS This package implements the following methods: exists exists(Str $key) : Any The exists method takes a name or index and returns truthy if an associated value exists. exists example #1 # given: synopsis $vars->exists('iam'); # truthy exists example #2 # given: synopsis $vars->exists('USER'); # truthy exists example #3 # given: synopsis $vars->exists('PATH'); # falsy exists example #4 # given: synopsis $vars->exists('user'); # truthy get get(Str $key) : Any The get method takes a name or index and returns the associated value. get example #1 # given: synopsis $vars->get('iam'); # ubuntu get example #2 # given: synopsis $vars->get('USER'); # ubuntu get example #3 # given: synopsis $vars->get('PATH'); # undef get example #4 # given: synopsis $vars->get('user'); # ubuntu name name(Str $key) : Any The name method takes a name or index and returns index if the the associated value exists. name example #1 # given: synopsis $vars->name('iam'); # USER name example #2 # given: synopsis $vars->name('USER'); # USER name example #3 # given: synopsis $vars->name('PATH'); # undef name example #4 # given: synopsis $vars->name('user'); # USER set set(Str $key, Maybe[Any] $value) : Any The set method takes a name or index and sets the value provided if the associated argument exists. set example #1 # given: synopsis $vars->set('iam', 'root'); # root set example #2 # given: synopsis $vars->set('USER', 'root'); # root set example #3 # given: synopsis $vars->set('PATH', '/tmp'); # undef # is not set set example #4 # given: synopsis $vars->set('user', 'root'); # root stashed stashed() : HashRef The stashed method returns the stashed data associated with the object. stashed example #1 # given: synopsis $vars->stashed AUTHOR Al Newkirk, awncorp@cpan.org LICENSE Copyright (C) 2011-2019, Al Newkirk, et al.
