PPI::Document::File(3) A Perl Document located in a specific file


WARNING: This class is experimental, and may change without notice

PPI::Document::File provides a PPI::Document subclass that represents a Perl document stored in a specific named file.



  my $file = PPI::Document::File->new( 'Module.pm' );

The "new" constructor works the same as for the regular one, except that the only params allowed is a file name. You cannot create an ``anonymous'' PPI::Document::File object, not can you create an empty one.

Returns a new PPI::Document::File object, or "undef" on error.


The "filename" accessor returns the name of the file in which the document is stored.


  # Save to the file we were loaded from
  # Save a copy to somewhere else
  $file->save( 'Module2.pm' );

The "save" method works similarly to the one in the parent PPI::Document class, saving a copy of the document to a file.

The difference with this subclass is that if "save" is not passed any filename, it will save it back to the file it was loaded from.

Note: When saving to a different file, it is considered to be saving a copy and so the value returned by the "filename" accessor will stay the same, and not change to the new filename.


- May need to overload some methods to forcefully prevent Document objects becoming children of another Node.
