PPI::Statement::Package - A package statement
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 :)
"PPI::Statement::Package" has a number of methods in addition to the standard
PPI::Statement, PPI::Node and PPI::Element methods.
Most package declarations are simple, and just look something like
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.
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.
