lib/cursor.js

The Cursor class is an internal class that embodies a cursor on MongoDB
allowing for iteration over the results returned from the underlying query.

CURSORS Cannot directly be instantiated

Example

var Server = require('mongodb-core').Server

, ReadPreference = require('mongodb-core').ReadPreference

, assert = require('assert');


var server = new Server({host: 'localhost', port: 27017});

// Wait for the connection event

server.on('connect', function(server) {

assert.equal(null, err);


// Execute the write

var cursor = _server.cursor('integration_tests.inserts_example4', {

find: 'integration_tests.example4'

, query: {a:1}

}, {

readPreference: new ReadPreference('secondary');

});


// Get the first document

cursor.next(function(err, doc) {

assert.equal(null, err);

server.destroy();

});

});


// Start connecting

server.connect();

lib/topologies/mongos.js

The Mongos class is a class that represents a Mongos Proxy topology and is
used to construct connections.

Example

var Mongos = require('mongodb-core').Mongos

, ReadPreference = require('mongodb-core').ReadPreference

, assert = require('assert');


var server = new Mongos([{host: 'localhost', port: 30000}]);

// Wait for the connection event

server.on('connect', function(server) {

server.destroy();

});


// Start connecting
