Class::MOP::Package - Package Meta Object
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.
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.
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.
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".
Creates a new anonymous package. Valid keys for %options are:
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.
Returns true if the package is an anonymous package.
This is returns the package's name, as passed to the constructor.
This returns a hash reference to the package's symbol table. The keys are symbol names and the values are typeglob references.
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.
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
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.
Returns true if there is a package variable defined for $variable_name. The $variable_name must contain a leading sigil.
This will remove the package variable specified $variable_name. The $variable_name must contain a leading sigil.
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.
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'.
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.
This will return a Class::MOP::Class instance for this class.
