PPI::Document::File - 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.
# Save to the file we were loaded from $file->save; # 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.
