$fdb = Net::FluidDB->new_for_testing(trace_http => 1);

# FluidDB client pointing to production
$fdb = Net::FluidDB->new(username => 'username', password => 'password');

# FluidDB taking credentials from environment variables
# FLUIDDB_USERNAME and FLUIDDB_PASSWORD
$fdb = Net::FluidDB->new;

# Resource getters
my $object     = $fdb->get_object($object_id, about => 1);
my $ns         = $fdb->get_namespace($path, description => 1);
my $tag        = $fdb->get_tag($path, description => 1);
my $policy     = $fdb->get_policy($user, $category, $action);
my $permission = $fdb->get_permission($category, $path, $action);
my $user       = $fdb->get_user($username);

USAGE

Class Methods

Your username in FluidDB. If not present uses the value of the environment variable FLUIDDB_USERNAME.

password

Your password in FluidDB. If not present uses the value of the environment variable FLUIDDB_PASSWORD.

protocol

Either 'HTTP' or 'HTTPS'. Defaults to 'HTTP'.

host

The FluidDB host. Defaults to fluiddb.fluidinfo.com.

trace_http_requests

A flag, logs all HTTP requests if true.

trace_http_responses

A flag, logs all HTTP responses if true.

trace_http

A flag, logs all HTTP requests and responses if true. (Shorthand for enabling the two above.)

Net::FluidDB->new_for_testing

Returns a Net::FluidDB instance pointing to the sandbox with "test"/"test". The host of the sandbox can be checked in the package variable $Net::FluidDB::SANDBOX_HOST.
