NAME
       Archive::Tar::File - a subclass for in-memory extracted
       file from Archive::Tar

SYNOPSIS
           my @items = $tar->get_files;

           print $_->name, ' ', $_->size, "\n" for @items;

           print $object->get_content;
           $object->replace_content('new content');

           $object->rename( 'new/full/path/to/file.c' );

DESCRIPTION
       Archive::Tar::Files provides a neat little object layer
       for in-memory extracted files. It's mostly used internally
       in Archive::Tar to tidy up the code, but there's no reason
       users shouldn't use this API as well.

       Accessors

       A lot of the methods in this package are accessors to the
       various fields in the tar header:

       name
           The file's name

       mode
           The file's mode

       uid The user id owning the file

       gid The group id owning the file

       size
           File size in bytes

       mtime
           Modification time. Adjusted to mac-time on MacOS if
           required

       chksum
           Checksum field for the tar header

       type
           File type -- numeric, but comparable to exported
           constants -- see Archive::Tar's documentation

       linkname
           If the file is a symlink, the file it's pointing to

       magic
           Tar magic string -- not useful for most users

       version
           Tar version string -- not useful for most users

       uname
           The user name that owns the file

       gname
           The group name that owns the file

       devmajor
           Device major number in case of a special file

       devminor
           Device minor number in case of a special file

       prefix
           Any directory to prefix to the extraction path, if any

       raw Raw tar header -- not useful for most users

Methods
       new( file => $path )

       Returns a new Archive::Tar::File object from an existing
       file.

       Returns undef on failure.

       new( data => $path, $data, $opt )

       Returns a new Archive::Tar::File object from data.

       $path defines the file name (which need not exist), $data
       the file contents, and $opt is a reference to a hash of
       attributes which may be used to override the default
       attributes (fields in the tar header), which are described
       above in the Accessors section.

       Returns undef on failure.

       new( chunk => $chunk )

       Returns a new Archive::Tar::File object from a raw
       512-byte tar archive chunk.

       Returns undef on failure.

       full_path

       Returns the full path from the tar header; this is
       basically a concatenation of the "prefix" and "name"
       fields.

       validate

       Done by Archive::Tar internally when reading the tar file:
       validate the header against the checksum to ensure integer
       tar file.

       Returns true on success, false on failure

       has_content

       Returns a boolean to indicate whether the current object
       has content.  Some special files like directories and so
       on never will have any content. This method is mainly to
       make sure you don't get warnings for using uninitialized
       values when looking at an object's content.

       get_content

       Returns the current content for the in-memory file

       get_content_by_ref

       Returns the current content for the in-memory file as a
       scalar reference. Normal users won't need this, but it
       will save memory if you are dealing with very large data
       files in your tar archive, since it will pass the contents
       by reference, rather than make a copy of it first.

       replace_content( $content )

       Replace the current content of the file with the new
       content. This only affects the in-memory archive, not the
       on-disk version until you write it.

       Returns true on success, false on failure.

       rename( $new_name )

       Rename the current file to $new_name.

       Note that you must specify a Unix path for $new_name,
       since per tar standard, all files in the archive must be
       Unix paths.

       Returns true on success and false on failure.

Convenience methods
       To quickly check the type of a "Archive::Tar::File"
       object, you can use the following methods:

       is_file
           Returns true if the file is of type "file"

           not happen after a successful "read".
