NAME

       MongoDB::OID - A Mongo ObjectId

SYNOPSIS

       If no "_id" field is provided when a document is inserted into the database, an "_id" field will be added with a new "MongoDB::OID" as its
       value.

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

       $id will be a "MongoDB::OID" 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.

       Warning: at the moment, OID generation is not thread safe.

ATTRIBUTES

   value
       The OID value. A random value will be generated if none exists already.	It is a 24-character hexidecimal string (12 bytes).

       Its string representation is the 24-character string.

METHODS

   to_string
	   my $hex = $oid->to_string;

       Gets the value of this OID as a 24-digit hexidecimal string.

   get_time
	   my $date = DateTime->from_epoch(epoch => $id->get_time);

       Each OID contains a 4 bytes timestamp from when it was created.	This method extracts the timestamp.

   TO_JSON
	   my $json = JSON->new;
	   $json->allow_blessed;
	   $json->convert_blessed;

	   $json->encode(MongoDB::OID->new);

       Returns a JSON string for this OID.  This is compatible with the strict JSON representation used by MongoDB, that is, an OID with the value
       "012345678901234567890123" will be represented as "{"$oid" : "012345678901234567890123"}".
