NAME

Net::FluidDB - A Perl interface to FluidDB

SYNOPSIS

 use Net::FluidDB;

 # predefined FluidDB client for playing around, points
 # to the sandbox with user test/test
 $fdb = Net::FluidDB->new_for_testing;
 $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;

DESCRIPTION

Net::FluidDB provides an interface to the FluidDB API.

The documentation of Net::FluidDB does not explain FluidDB, though there are links to relevant pages in the documentation of each class.

BETA VERSION

Net::FluidDB is in beta stage. A beta in terms of interface mostly, the entire API is implemented except for tag values (see below). The module has good test coverage (~1700 tests in the full suite), and is well-documented.

It is a beta because:

• The overall interface is taking shape. I consider the basis to be there, but I may still fine-tune some detail. I may still do backward-incompatible modifications, though I don't expect them to be anything but minor at this point.

• In particular, since FluidDB is new usage patterns have yet to arise. They may influence the design of the interface.

• Tagging with anything but a native FluidDB type is unsupported. The very API in FluidDB is gonna be revised soon on this point so I am waiting.

• As of this version calls to FluidDB return a status flag. If there was any failure the module only prints the response headers to STDERR and returns false.

Forthcoming versions will address those points.

Class Methods

Net::FluidDB->new(%attrs)

Returns an object for communicating with FluidDB.

This is a wrapper around LWP::UserAgent and does not validate credentials in the very constructor. If they are wrong requests will fail when performed.

Attributes and options are:

username

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.

Instance Methods

$fdb->username

$fdb->username($username)

Gets/sets the username.

$fdb->password

$fdb->password($password)

Gets/sets the password.

$fdb->protocol

$fdb->protocol($protocol)

Gets/sets the protocol, either 'HTTP' or 'HTTPS'.

$fdb->ua

Returns the instance of LWP::UserAgent used to communicate with FluidDB.

$fdb->user

Returns the user on behalf of whom fdb is doing calls. This attribute is lazy loaded.
