NAME

       PPI::Statement::Package - A package statement

INHERITANCE

         PPI::Statement::Package
         isa PPI::Statement
             isa PPI::Node
                 isa PPI::Element

DESCRIPTION

       Most PPI::Statement subclasses are assigned based on the value of the first token or word
       found in the statement. When PPI encounters a statement starting with 'package', it
       converts it to a "PPI::Statement::Package" object.

       When working with package statements, please remember that packages only exist within
       their scope, and proper support for scoping has yet to be completed in PPI.

       However, if the immediate parent of the package statement is the top level PPI::Document
       object, then it can be considered to define everything found until the next top-level
       "file scoped" package statement.

       A file may, however, contain nested temporary package, in which case you are mostly on
       your own :)

METHODS

       "PPI::Statement::Package" has a number of methods in addition to the standard
       PPI::Statement, PPI::Node and PPI::Element methods.

   namespace
       Most package declarations are simple, and just look something like

         package Foo::Bar;

       The "namespace" method returns the name of the declared package, in the above case
       'Foo::Bar'. It returns this exactly as written and does not attempt to clean up or resolve
       things like ::Foo to main::Foo.

       If the package statement is done any different way, it returns false.

   version
       Some package declarations may include a version:

         package Foo::Bar 1.23;
         package Baz v1.23;

       The "version" method returns the stringified version as seen in the document (if any),
       otherwise the empty string.

   file_scoped
       Regardless of whether it is named or not, the "file_scoped" method will test to see if the
       package declaration is a top level "file scoped" statement or not, based on its location.

       In general, returns true if it is a "file scoped" package declaration with an immediate
       parent of the top level Document, or false if not.

       Note that if the PPI DOM tree does not have a PPI::Document object at as the root element,
       this will return false. Likewise, it will also return false if the root element is a
       PPI::Document::Fragment, as a fragment of a file does not represent a scope.

SUPPORT
