### How it works ###
Translating into code how the API settings are used, it is as simple as having
an instance of the mobi.mtld.da.device.Config class into the
mobi.mtld.da.device.DeviceApi object and the respective Config public methods
to check the wished settings and make the API work according to them.
#### Use of the default settings ####
When a new instance of the mobi.mtld.da.device.DeviceApi class is created,
internally another instance of the mobi.mtld.da.device.Config class is generated
with the default settings.
```javascript
var DeviceApi = require('deviceatlas-deviceapi').DeviceApi;
var deviceApi = new DeviceApi();
```
#### Use of custom settings ####
In order to use custom settings, You may create a json in which the
Config object is created inside the deviceapi.
```javascript
var DeviceApi = require('deviceatlas-deviceapi').DeviceApi;
/* Preferred method */
deviceApi = new DeviceApi({maxCacheEntries: 4096});
```
Alternatively you may to explicitly create a
Config object, set the settings and pass it to the DeviceApi instance.
```javascript
var DeviceApi = require('deviceatlas-deviceapi').DeviceApi;
var Config = require('deviceatlas-deviceapi').Config;
/* Alternative method */
config = new Config();
config.maxCacheEntries = 1024;
deviceApi = new DeviceApi(config);
```
```javascript
var DeviceApi = require('deviceatlas-deviceapi').DeviceApi;
var Config = require('deviceatlas-deviceapi').Config;
/* Alternative method */
deviceApi = new DeviceApi();
config = new Config();
deviceApi.config = config;
```
### Example of use case ###
For the scenario your system works, it is highly recommended to configure the
API with the most convenient settings in order to enhance performance, memory
footprint and, in general, provide a better user experience.
```javascript
var DeviceApi = require('deviceatlas-deviceapi').DeviceApi;
var Config = require('deviceatlas-deviceapi').Config;
/* Reduce response time and memory footprint for a web application */
config = new Config();
// Set the number of maximum entries held in the internal cache.
config.maxCacheEntries = 4096;
// Boost API performance by ignoring dynamic properties if they are not part of
// the property set you expect.
// Finally set the config to our new instance of the DeviceAtlas API.
deviceApi = new DeviceApi(config);
```
