Communication

1. Purpose

This module defines core enumerations and delegates used for representing the outcomes of communication operations and for implementing callback mechanisms in the DTS communication subsystem. It serves as a shared contract between communication implementations and higher-level consumers, ensuring consistent reporting of connection, disconnection, send, receive, and cancellation events across the system.

---

2. Public Interface

• CommunicationResult enum
  A strongly-typed enumeration of possible outcomes for communication operations. Each value corresponds to a specific state or result of a communication action:

  • ConnectOK, ConnectFailed, ConnectTimeout — outcomes of a connection attempt.
  • DisconnectOK, DisconnectFailed, DisconnectTimeout — outcomes of a disconnection attempt.
  • SendOK, SendFailed, SendTimeout — outcomes of a send operation.
  • ReceiveOK, ReceiveFailed, ReceiveTimeout — outcomes of a receive operation.
  • Canceled — indicates the operation was canceled (e.g., by user or timeout).

• CommunicationCallback delegate

  public delegate bool CommunicationCallback(ICommunicationReport report);
  

  A function pointer type used to register callbacks that process communication reports. It takes an ICommunicationReport instance as input and returns a bool (typically indicating whether the callback handled the report successfully or whether further processing should continue).

---

3. Invariants

• The CommunicationResult enum values are exhaustive for reporting the status of communication operations; no other result codes are defined in this module.
• Callbacks registered via CommunicationCallback must accept and process an ICommunicationReport instance; the return value semantics (e.g., true = handled, false = not handled) are implied by usage but not enforced by this module.
• No runtime validation or normalization of enum values is performed in this module; consumers are responsible for interpreting results consistently.

---

4. Dependencies

• Dependencies of this module:

  • DTS.Common.Interface.Communication.ICommunicationReport — referenced by the CommunicationCallback delegate. This interface is expected to define the contract for communication reports (e.g., containing result type, timestamp, payload, etc.), but its definition is not included here.

• Dependencies on this module:

  • Any module implementing or consuming communication operations (e.g., network drivers, protocol handlers, UI components) is expected to reference this module to interpret operation outcomes and register callbacks.
  • The namespace DTS.Common.Enums.Communication suggests this is part of a shared common library (DTS.Common), implying usage across multiple components in the DTS ecosystem.

---

5. Gotchas

• No explicit mapping between CommunicationResult and ICommunicationReport is defined here — consumers must infer how report contents (e.g., ICommunicationReport.Result) correspond to CommunicationResult enum values.
• Canceled is a generic result — it does not specify which operation was canceled (e.g., connect vs. send); callers must inspect the report context (e.g., via ICommunicationReport.OperationType, if defined) to disambiguate.
• Return value semantics of CommunicationCallback are not standardized in this file — the meaning of true/false depends on the calling convention (e.g., chain-of-responsibility vs. fire-and-forget).
• No error codes or exception details are included — the enum only captures high-level outcomes; detailed diagnostics must be embedded in the ICommunicationReport instance passed to callbacks.

None identified beyond the above.
