=head1 NAME

Net::Google::Drive::Simple::Item - Representation of a Google Drive File

=head1 SYNOPSIS

    use feature 'say';
    use Net::Google::Drive::Simple;

    # requires a ~/.google-drive.yml file with an access token,
    # see description from Net::Google::Drive::Simple

    my $gd = Net::Google::Drive::Simple->new();
    my $children = $gd->children( "/" ); # or any other folder /path/location

    foreach my $item ( @$children ) {
        # $item is one Net::Google::Drive::Simple::Item object

        if ( $item->is_folder ) {
            say "** ", $item->title, " is a folder";
        } else {
            say $item->title, " is a file ", $item->mimeType;
            eval { # originalFilename not necessary available for all files
               say $item->originalFilename(), " can be downloaded at ", $item->downloadUrl();
            };
        }
    }

=head1 DESCRIPTION

Net::Google::Drive::Simple::Item provides a class to manipulate the
File methadata from Google Drive API.

    https://developers.google.com/drive/api/v3/reference/files

=head2 GETTING STARTED

This class should not be used directly, and you should use
L<Net::Google::Drive::Simple> as shown in the synopsis.

=head1 METHODS

=over 4

=item C<new( $data )>

Constructor, creates one object which hold on hash ref C<$data>
to manipulate the metadata for a file.
All the keys from the hash below as documented in L<Google Drive API Doc|https://developers.google.com/drive/api/v3/reference/files>
are mapped using AUTOLOAD so you can use helpers for every first level entry like these:

        $file->kind;
        $file->id;
        $file->name;
        $file->mimeType;

=item C<$file-E<gt>is_folder>

Return a boolean '1' or '0' to indicate if the current file
is one folder or not. (this is using the mimeType value).

    $iterm->is_folder

=item C<$file-E<gt>is_file>

Return a boolean '1' or '0' to indicate if the current file
is a regular file (not a folder).
(this is using the mimeType value).

     $iterm->is_file or ! $iterm->is_folder

=item C<$file-E<gt>kind>

Identifies what kind of resource this is. Value: the fixed string "drive#file".

=item C<$file-E<gt>id>

The ID of the file.

=item C<$file-E<gt>name>

The name of the file. This is not necessarily unique within a folder.
Note that for immutable items such as the top level folders of shared drives, My Drive root folder,
and Application Data folder the name is constant.

=item C<$file-E<gt>mimeType>

The MIME type of the file.
Google Drive will attempt to automatically detect an appropriate value from uploaded content if no value is provided. The value cannot be changed unless a new revision is uploaded.

If a file is created with a Google Doc MIME type, the uploaded content will be imported if possible. The supported import formats are published in the About resource.

=item C<$file-E<gt>description>

A short description of the file.

=item C<$file-E<gt>starred>

boolean - Whether the user has starred the file.

=item C<$file-E<gt>trashed>

boolean - Whether the file has been trashed, either explicitly or from a trashed parent folder. Only the owner may trash a file, and other users cannot see files in the owner's trash.

=item C<$file-E<gt>explicitlyTrashed>

boolean - Whether the file has been explicitly trashed, as opposed to recursively trashed from a parent folder.

=item C<$file-E<gt>version>

A monotonically increasing version number for the file. This reflects every change made to the file on the server, even those not visible to the user.

=item C<$file-E<gt>createdTime>

The time at which the file was created (RFC 3339 date-time).

=item C<$file-E<gt>modifiedTime>

The last time the file was modified by anyone (RFC 3339 date-time).
Note that setting modifiedTime will also update modifiedByMeTime for the user.

=item C<$file-E<gt>size>

The size of the file's content in bytes. This is only applicable to files with binary content in Google Drive.

=item C<$file-E<gt>capabilities>

Capabilities the current user has on this file. Each capability corresponds to a fine-grained action that a user may take.

=head1 Tips

=head2 AUTOLOAD

The implemented AUTOLOAD function is case insensitive.
The following functions C<$iterm->id>, C<$iterm->ID> and C<$iterm->Id>
for example are all equivalent and return the 'id' for the file.


When trying to access to an unknown field, the code will die/throw an exception.

     eval { $item->DoNotExist } and $@ =~ m{"Cannot find any attribute named 'DoNotExist'}
