PPI::Statement::Package - A package statement
PPI::Statement::Package isa PPI::Statement isa PPI::Node isa PPI::Element
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
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 :)
Most package declarations are simple, and just look something like
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.
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.
