DESCRIPTION
A Catmandu::Store::File::Memory::Index contains all "folders" available in a Catmandu::Store::File::Memory 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::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);
