* EE_Gateway |
10
|
|
|
* Abstract base class for all gateways for processing payments. |
11
|
|
|
* This has been designed in a way so that other WP Plugins |
12
|
|
|
* can use this class for processing payments, and theoretically any of its children, |
13
|
|
|
* provided they implement the interfaces it uses. |
14
|
|
|
* The necessary interfaces to be implemented are found in: |
15
|
|
|
* /core/interfaces/payments/ and /core/interfaces/ |
16
|
|
|
* After constructing a gateway object, you need to set all the properties which reference many of the |
17
|
|
|
* needed helpers and models (see all the methods starting with "set_", |
18
|
|
|
* eg seg_line_item_helper which should be passed an object which implements EEHI_Line_Item_Helper; etc). |
