* Class Query |

* @package RemoteRequest\Protocols\Fsp |
|
12
|
|
|
* Simple FSP query to remote source - create packet |
|
13
|
|
|
* This is the "transport box" |
|
14
|
|
|
* @todo: throw compute checksum and packet building outside this class; that's logic, not pure data |
|
15
|
|
|
* then getData() call can have that logic |
|
16
|
|
|
* - X - -> re-define where are the data storages (local - this class; and remote - the packet into the run) |
|
17
|
|
|
* - then it's simple case of many adapters and that calculating calls should be there |
|
18
|
|
|
* - Adapters in HTTP are descendants of Dummy\Query and Dummy\Answer |
