NAME
Class::MOP::Package - Package Meta Object
VERSION
version 2.2201
DESCRIPTION
The Package Protocol provides an abstraction of a Perl 5 package. A package is basically namespace, and this module provides methods for looking at and changing that namespace's symbol table.
METHODS
Class::MOP::Package->initialize($package_name, %options)
This method creates a new
Class::MOP::Package
instance which represents specified package. If an existing metaclass object exists for the package, that will be returned instead. No options are valid at the package level.Class::MOP::Package->reinitialize($package, %options)
This method forcibly removes any existing metaclass for the package before calling
initialize
. In contrast toinitialize
, you may also pass an existingClass::MOP::Package
instance instead of just a package name as$package
.Do not call this unless you know what you are doing.
Class::MOP::Package->create($package, %options)
Creates a new
Class::MOP::Package
instance which represents the specified package, and also does some initialization of that package. Currently, this just does the same thing asinitialize
, but is overridden in subclasses, such asClass::MOP::Class
.Class::MOP::Package->create_anon(%options)
Creates a new anonymous package. Valid keys for
%options
are:cache
-
If this will be
true
(the default isfalse
), the instance will be cached inClass::MOP
's metaclass cache. weaken
-
If this is
true
(the defaulttrue
when cache isfalse
), the instance stored inClass::MOP
's metaclass cache will be weakened, so that the anonymous package will be garbage collected when the returned instance goes out of scope.
$metapackage->is_anon
Returns true if the package is an anonymous package.
$metapackage->name
This is returns the package's name, as passed to the constructor.
$metapackage->namespace
This returns a hash reference to the package's symbol table. The keys are symbol names and the values are typeglob references.
$metapackage->add_package_symbol($variable_name, $initial_value)
This method accepts a variable name and an optional initial value. The
$variable_name
must contain a leading sigil.This method creates the variable in the package's symbol table, and sets it to the initial value if one was provided.
$metapackage->get_package_symbol($variable_name)
Given a variable name, this method returns the variable as a reference or undef if it does not exist. The
$variable_name
must contain a leading sigil.$metapackage->get_or_add_package_symbol($variable_name)
Given a variable name, this method returns the variable as a reference. If it does not exist, a default value will be generated if possible. The
$variable_name
must contain a leading sigil.$metapackage->has_package_symbol($variable_name)
Returns true if there is a package variable defined for
$variable_name
. The$variable_name
must contain a leading sigil.$metapackage->remove_package_symbol($variable_name)
This will remove the package variable specified
$variable_name
. The$variable_name
must contain a leading sigil.$metapackage->remove_package_glob($glob_name)
Given the name of a glob, this will remove that glob from the package's symbol table. Glob names do not include a sigil. Removing the glob removes all variables and subroutines with the specified name.
$metapackage->list_all_package_symbols($type_filter)
This will list all the glob names associated with the current package. These names do not have leading sigils.
You can provide an optional type filter, which should be one of 'SCALAR', 'ARRAY', 'HASH', or 'CODE'.
$metapackage->get_all_package_symbols($type_filter)
This works much like
list_all_package_symbols
, but it returns a hash reference. The keys are glob names and the values are references to the value for that name.Class::MOP::Package->meta
This will return a Class::MOP::Class instance for this class.
