Class: SessionLifecycle

Defined in: ../../../adapters/core/src/session/utilities.ts:38

Manages session lifecycle and abort handling.

Provides coordinated abort signal management:

• Idempotent abort()
• Cleanup hook execution
• Termination state tracking

Design Philosophy

SessionLifecycle is a simple composition utility that encapsulates abort signal coordination. It avoids inheritance coupling while providing a clean API for session termination.

Example Usage

class MySession {
  private lifecycle = new SessionLifecycle();

  abort() {
    this.lifecycle.abort(() => this.transport.close());
  }

  async sendMessage(msg: string) {
    if (this.lifecycle.isTerminated) {
      throw new Error('Session terminated');
    }
    // ... send logic
  }

  getAbortSignal(): AbortSignal {
    return this.lifecycle.signal;
  }
}
