SmppSession
public interface SmppSession
SmppSession defines the core interface for managing an SMPP session, whether initiated by a client or accepted by a server. It exposes lifecycle control, state tracking, PDU transmission, and session configuration. This interface is central to the operation of both client and server-side SMPP interactions.
Use this interface to interact with a session after a connection has been established, including sending and receiving PDUs, handling state transitions, and managing session termination.
Fields:
| Field | Description |
| int STATE_INITIAL | Initial state before any connection is made. |
| int STATE_OPEN | TCP connection established, waiting for bind. |
| int STATE_BINDING | Bind request in progress. |
| int STATE_BOUND | Bind accepted, session is active. |
| int STATE_UNBINDING | Unbind request in progress. |
| int STATE_CLOSED | Session closed. |
| String[] STATES | Array of state names (indexed by the constants above). |
Methods:
| SmppBindType getBindType() | Returns the type of bind (e.g., receiver, transmitter, transceiver). |
| SmppSession.Type getLocalType() | Gets the local session type (client or server). |
| SmppSession.Type getRemoteType() | Gets the remote session type. |
| SmppSessionConfiguration getConfiguration() | Returns the current session configuration. |
| String getStateName() | Returns a human-readable name of the current session state. |
| SmppVersion getInterfaceVersion() | Returns the negotiated SMPP version. |
| boolean areOptionalParametersSupported() | Indicates if TLV optional parameters are supported in this session. |
| boolean isOpen() | Returns true if the session is connected. |
| boolean isBinding() | Returns true if the session is in the process of binding. |
| boolean isBound() | Returns true if the session is fully bound and operational. |
| boolean isUnbinding() | Returns true if the session is unbinding. |
| boolean isClosed() | Returns true if the session is closed. |
| long getBoundTime() | Returns the system timestamp when the session was successfully bound. |
| void close() | Actively closes the session. |
| void passiveClose() | Passively closes the session (typically on remote close). |
| void unbind(long timeoutMillis) | Sends an unbind request and waits for the session to close. |
| void destroy() | Immediately terminates and cleans up the session. |
| void bind(BaseBind request, long timeoutMillis) |
Sends a bind request with a timeout. Throws: RecoverablePduException, UnrecoverablePduException, SmppTimeoutException, SmppChannelException, InterruptedException |
| void sendRequestPdu(PduRequest<?> request) |
Sends a request PDU to the remote peer. Throws: RecoverablePduException, UnrecoverablePduException, SmppTimeoutException, SmppChannelException, InterruptedException |
| void sendResponsePdu(PduResponse response) |
Sends a response PDU back to the peer. Throws: RecoverablePduException, UnrecoverablePduException, SmppChannelException, InterruptedException |
