#### Basic Example
``js
var connect = require('vsphere-connect');

// create a client and automatically log in
connect.createClient({
host: 'vcenter.mydomain.com',
username: 'administrator@vsphere.local',
password: 'vmware1',
ignoreSSL: true,
autoLogin: true
})
.then(function(client) {

// retrieve 2 virtual machines by id
return client.retrieve({
type: 'VirtualMachine',
id: ['vm-1234', 'vm-5678'],
properties: ['name', 'config.version']
})
.then(function(results) {
// process results
});
})
.caught(function(err) {
// handle error
});

##### connect.createClient(args)
Creates a new vSphere client

Parameters
* args {Object} - Arguments hash

---

##### client.destroy(args)
Destroy a Managed Object

Parameters
* args {Object} - Arguments hash
* type {string} - Managed Object type
* id {string} - Id of object to destroy
* [async=true] {boolean} - If false, the task generated will be monitored to completion and returned
* [delay=1000] {number} - Delay in milliseconds between monitor queries for async=false
* [timeout=0] {number} - Time in milliseconds before the monitor operation should timeout, 0 for never

Returns {Promise} - Returns a Promise that resolves to the ManagedObjectReference of the destroy task

---

##### client.rename(args)

Returns {Promise} - Returns a Promise that resolves to the ManagedObjectReference of the rename task

---

##### client.findParentType(args)
Finds the next parent of a specific type from a starting object (i.e. find the cluster a VM is located in even if there are resource pools in between). Optionally if parent types are nested (like resource pools) a root option can be passed to get the root parent type.

Parameters
* args {Object} - Arguments hash

##### client.monitor.task(id, [delay], [timeout])
Monitors a task until it completes or times out

Parameters
* id {String} - Task id to monitor

* [timeout=0] {number} - Time in milliseconds before the monitor times out. 0 for no timeout

Returns {Promise} - Returns a Promise that resolves to task info after the task has been completed

Events
* task.state {Object} - Emits the task id and state on each poll cycle


##### util.moRef(type, id)

$3

vsphere-connect has the option to periodically query the viServer for recent events. These events are then emitted from the client. This means that events are not real time but may still be useful. A user defined interval for polling can be set when creating the client to allow for more frequent event queries. The event monitor also emits an emitlog event after every interval so it can also be used to track the status of the event monitor.

#### Generic Method Example

`js
var connect = require('vsphere-connect');
var util = connect.util;

// create a client and automatically log in
connect.createClient({
host: 'vcenter.mydomain.com',
username: 'administrator@vsphere.local',
password: 'vmware1',
ignoreSSL: true,
autoLogin: true
})
.then(function(client) {

// create a destroy task to remove a vm
return client.method('Destroy_Task', {
_this: util.moRef('VirtualMachine', 'vm-123')
})
.then(function(result) {
// process the results
});
});

`

#### Event Example

`js
var connect = require('vsphere-connect');
var util = connect.util;

// create a client and automatically log in
connect.createClient({
host: 'vcenter.mydomain.com',
username: 'administrator@vsphere.local',
password: 'vmware1',
ignoreSSL: true,
autoLogin: true,
events: {
interval: 10000 // every 10 seconds
}
})
.then(function(client) {

// add event listener
client.on('TaskEvent', function(task) {
// process task
});
});
