/**
|
|
* The bridge interface
|
|
*
|
|
* A bridge is a class that is responsible for collecting and transforming data
|
|
* from one hosting provider into an internal representation of feed data, that
|
|
* can later be transformed into different feed formats (see {@see FormatInterface}).
|
|
*
|
|
* For this purpose, all bridges need to perform three common operations:
|
|
*
|
|
* 1. Collect data from a remote site.
|
|
* 2. Extract the required contents.
|
|
* 3. Add the contents to the internal data structure.
|
|
*
|
|
* Bridges can optionally specify parameters to customize bridge behavior based
|
|
* on user input. For example, a user could specify how many items to return in
|
|
* the feed and where to get them.
|
|
*
|
|
* In order to present a bridge on the home page, and for the purpose of bridge
|
|
* specific behaviour, additional information must be provided by the bridge:
|
|
*
|
|
* * **Name**
|
|
* The name of the bridge that can be displayed to users.
|
|
*
|
|
* * **Description**
|
|
* A brief description for the bridge that can be displayed to users.
|
|
*
|
|
* * **URI**
|
|
* A link to the hosting provider.
|
|
*
|
|
* * **Maintainer**
|
|
* The GitHub username of the bridge maintainer
|
|
*
|
|
* * **Parameters**
|
|
* A list of parameters for customization
|
|
*
|
|
* * **Icon**
|
|
* A link to the favicon of the hosting provider
|
|
*
|
|
* * **Cache timeout**
|
|
* The default cache timeout for the bridge.
