Methods

doConnect()

protected doConnect(auth): Promise<void>

Defined in: packages/agentos/src/channels/adapters/SignalChannelAdapter.ts:113

Establish the platform connection using the supplied credentials. Called by initialize after state has been set to connecting. Must throw on failure — the base class handles retry and state changes.

Parameters

auth

ChannelAuthConfig & object

Returns

Promise<void>

Overrides

BaseChannelAdapter.doConnect

---

doSendMessage()

protected doSendMessage(conversationId, content): Promise<ChannelSendResult>

Defined in: packages/agentos/src/channels/adapters/SignalChannelAdapter.ts:156

Deliver a message to the external platform. Called by sendMessage only when the adapter is connected.

Parameters

conversationId

string

content

MessageContent

Returns

Promise<ChannelSendResult>

Overrides

BaseChannelAdapter.doSendMessage

---

doShutdown()

protected doShutdown(): Promise<void>

Defined in: packages/agentos/src/channels/adapters/SignalChannelAdapter.ts:206

Release platform resources (close WebSocket, stop polling, etc.). Called by shutdown before the state transitions to disconnected.

Returns

Promise<void>

Overrides

BaseChannelAdapter.doShutdown

---

emit()

protected emit(event): void

Defined in: packages/agentos/src/channels/adapters/BaseChannelAdapter.ts:265

Emit an event to all matching subscribers. Subclasses call this when the platform SDK receives an inbound event.

Parameters

event

ChannelEvent

Returns

void

Inherited from

BaseChannelAdapter.emit

---

emitConnectionChange()

protected emitConnectionChange(): void

Defined in: packages/agentos/src/channels/adapters/BaseChannelAdapter.ts:296

Convenience helper: emit a connection_change event with the current status. Called automatically by setStatus.

Returns

void

Inherited from

BaseChannelAdapter.emitConnectionChange

---

getConnectionInfo()

getConnectionInfo(): ChannelConnectionInfo

Defined in: packages/agentos/src/channels/adapters/BaseChannelAdapter.ts:205
