NAME

       Catmandu::Store::File::Simple::Index - Index of all "Folders" in a
       Catmandu::Store::File::Simple

SYNOPSIS

           use Catmandu;

           my $store = Catmandu->store('File::Simple' , root => 't/data');

           my $index = $store->index;

           # List all containers
           $index->each(sub {
               my $container = shift;

               print "%s\n" , $container->{_id};
           });

           # Add a new folder
           $index->add({_id => '1234'});

           # Delete a folder
           $index->delete(1234);

           # Get a folder
           my $folder = $index->get(1234);

           # Get the files in an folder
           my $files = $index->files(1234);

           $files->each(sub {
               my $file = shift;

               my $name         = $file->_id;
               my $size         = $file->size;
               my $content_type = $file->content_type;
               my $created      = $file->created;
               my $modified     = $file->modified;

               $file->stream(IO::File->new(">/tmp/$name"), file);
           });

           # Add a file
           $files->upload(IO::File->new("<data.dat"),"data.dat");

           # Retrieve a file
           my $file = $files->get("data.dat");

           # Stream a file to an IO::Handle
           $files->stream(IO::File->new(">data.dat"),$file);

           # Delete a file
           $files->delete("data.dat");

           # Delete a folders
           $index->delete("1234");

DESCRIPTION

       A Catmandu::Store::File::Simple::Index contains all "folders" available in a
       Catmandu::Store::File::Simple FileStore. All methods of Catmandu::Bag,
       Catmandu::FileBag::Index and Catmandu::Droppable are implemented.

       Every Catmandu::Bag is also an Catmandu::Iterable.

FOLDERS

       All files in a Catmandu::Store::File::Simple are organized in "folders". To add a "folder"
       a new record needs to be added to the Catmandu::Store::File::Simple::Index :

           $index->add({_id => '1234'});

       The "_id" field is the only metadata available in Simple stores. To add more metadata
       fields to a Simple store a Catmandu::Plugin::SideCar is required.

FILES

       Files can be accessed via the "folder" identifier:

           my $files = $index->files('1234');

       Use the "upload" method to add new files to a "folder". Use the "download" method to
       retrieve files from a "folder".

           $files->upload(IO::File->new("</tmp/data.txt"),'data.txt');

           my $file = $files->get('data.txt');

           $files->download(IO::File->new(">/tmp/data.txt"),$file);

INHERITED METHODS

       This Catmandu::Bag implements:

       Catmandu::Bag
       Catmandu::FileBag::Index
       Catmandu::Droppable
