*
|
* This class is a sequential id generator. A simple use of this class would be like so:
|
*
|
* Ext.define('MyApp.data.MyModel', {
|
* extend: 'Ext.data.Model',
|
* idgen: 'sequential'
|
* });
|
* // assign id's of 1, 2, 3, etc.
|
*
|
* An example of a configured generator would be:
|
*
|
* Ext.define('MyApp.data.MyModel', {
|
* extend: 'Ext.data.Model',
|
* idgen: {
|
* type: 'sequential',
|
* prefix: 'ID_',
|
* seed: 1000
|
* }
|
* });
|
* // assign id's of ID_1000, ID_1001, ID_1002, etc.
|
*
