Base Classes

Before we dive into individual class descriptions, it's important to understand the class hierarchy that underpins the Mobius SMPP API. All SMPP commands - both requests and responses - inherit from a shared set of base classes that define common behavior for encoding, decoding, and managing PDU content.
This inheritance model provides a consistent interface for working with SMPP commands, whether you're handling a SubmitSm, a BindReceiver, or a DeliverSmResp.

Hierarchy

Pdu
├── PduRequest<T extends PduResponse>
│   ├── BaseBind<T>         // Used for bind-related commands
│   │   └── BindReceiver, BindTransmitter, BindTransceiver
│   ├── BaseSm<T>           // Used for message-related commands
│   │   └── SubmitSm, DeliverSm, SubmitMulti, etc.
│   └── Other request types (QuerySm, CancelSm, etc.)
└── PduResponse
    └── SubmitSmResp, DeliverSmResp, BindReceiverResp, etc.
