NAME

MorboDB::OID - An object ID in MorboDB

VERSION

version 0.001001

SYNOPSIS

When inserting documents into a collection, if you don't provide an '_id' attribute, this module will create one automatically.

        my $id = $collection->insert({ name => 'Alice', age => 20 });

$id will be a MorboDB::OID object that can be used to retreive or update the saved document:

        $collection->update({ _id => $id }, { age => { '$inc' => 1 } });
        # now Alice is 21

To create a copy of an existing OID, you must set the value attribute in the constructor. For example:

        my $id1 = MongoDB::OID->new;
        my $id2 = MongoDB::OID->new(value => $id1->value);

Now $id1 and $id2 will have the same value.

DESCRIPTION

A MorboDB::OID object uniquely represents a document in a MorboDB::Collection. When you don't provide a documents with the '_id' attribute during insertion, this module will create an ID automatically.

OIDs in MorboDB are created using Data::UUID, so they are 36-characters long and do not resemble OIDs in MongoDB.

ATTRIBUTES

value

A 36-characters long string representation of the OID in conventional UUID format. See UUID on Wikipedia for more information on UUID format.

OBJECT METHODS

to_string()

This really just returns the 'value' attribute.

get_time()

Not implemented. Only returns undef here.

TO_JSON()

Meant to be called by the JSON family of modules to create a JSON representation of the OID. So, for example, "4162F712-1DD2-11B2-B17E-C09EFE1DC403" will be represented as { "$oid" : "4162F712-1DD2-11B2-B17E-C09EFE1DC403" }.

        my $json = JSON->new->allow_blessed->convert_blessed;
        $json->encode(MorboDB::OID->new);

DIAGNOSTICS

This module does not throw any errors of its own.
