NAME

       Class::MOP::Package - Package Meta Object

VERSION

       version 2.1005

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 to "initialize", you may also pass an existing
           "Class::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 as "initialize", but is overridden in subclasses, such as "Class::MOP::Class".

       Class::MOP::Package->create_anon(%options)
           Creates a new anonymous package. Valid keys for %options are:

           "weaken"
               If this is true (the default), the instance stored in "Class::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.
