SYNOPSIS

use Catmandu;

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

});

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

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

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

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

DESCRIPTION

A Catmandu::Store::File::Memory::Bag contains all "files" available in a Catmandu::Store::File::Memory FileStore "folder". 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::Memory are organized in "folders". To add a "folder" a new record needs to be added to the Catmandu::Store::File::Memory::Index :

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

The _id field is the only metadata available in Memory stores. To add more metadata fields to a Memory 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);
