NAME

# create
$ns = Net::FluidDB::Namespace->new(
   fdb         => $fdb,
   description => $description,
   path        => $path
);
$ns->create;

# get, optionally fetching descrition
$ns = Net::FluidDB::Namespace->get($fdb, $path, description => 1);
$ns->parent;

# update
$ns->description($new_description);
$ns->update;

# delete
$ns->delete;

DESCRIPTION

Net::FluidDB::Namespace models FluidDB namespaces.

USAGE

Inheritance

Net::FluidDB::Namespace is a subclass of Net::FluidDB::Base.

Roles

Net::FluidDB::Namespace consumes the role Net::FluidDB::HasObject.

Class methods

Net::FluidDB::Namespace->new(%attrs)

Constructs a new namespace. The constructor accepts these parameters:

fdb (required)

An instance of Net::FluidDB.

description (optional)

A description of this namespace.

parent (optional, but dependent)

The namespace you want to put this namespace into. An instance of Net::FluidDB::Namespace representing an existing namespace in FluidDB.

name (optional, but dependent)

The name of the namespace, which is the rightmost segment of its path. The name of "fxn/perl" is "perl".

path (optional, but dependent)

The path of the namespace, for example "fxn/perl".

The description attribute is not required because FluidDB allows fetching namespaces without their description. It must be defined when creating or updating namespaces though.

The attributes parent, path, and name are mutually dependent. Ultimately namespace creation has to be able to send the path of the parent and the name of the namespace to FluidDB. So you can set parent and name, or just path.

This constructor is only useful for creating new namespaces in FluidDB. Existing namespaces are fetched with get.

Net::FluidDB::Namespace->get($fdb, $path, %opts)

Retrieves the namespace with path $path from FluidDB. Options are:

description (optional, default false)

Tells get whether you want to fetch the description.

namespace_names (optional, default false)

Tells get whether you want to fetch the names of child namespaces.

tag_names (optional, default false)

Tells get whether you want to fetch the names of child tags.

Instance Methods

$ns->create

Creates the namespace in FluidDB.

$ns->update

Updates the namespace in FluidDB. Only the description can be modified.

$ns->delete

Deletes the namespace in FluidDB.

$ns->description
$ns->description($description)

Gets/sets the description of the namespace.

Note that you need to set the description flag when you fetch a namespace for this attribute to be initialized.

$ns->namespace_names

Returns the names of the child namespaces as a (possibly empty) arrayref of strings.

Note that you need to set the namespace_names flag when you fetch a namespace for this attribute to be initialized.

$ns->tag_names

Returns the names of the child tags as a (possibly empty) arrayref of strings.

Note that you need to set the tag_names flag when you fetch a namespace for this attribute to initialized.

$ns->parent

The parent of the namespace, as an instance of Net::FluidDB::Namespace. This attribute is lazy loaded.

$ns->name

The name of the namespace.

$ns->path

The path of the namespace.
