ThreadStatus

Tracks the state of a thread throughout its lifecycle using bitwise flags to efficiently represent and check multiple states. Provides convenient boolean accessors for checking specific states.

const status = new ThreadStatus()
status.value = Status.READY

// Check if thread is ready
if (status.READY) {
  console.log('Thread is ready to start')
}

// Check if thread completed with an error
if (status.ERROR) {
  console.log('Thread encountered an error')
}

Constants​

Status​

Constants representing different thread states using bitwise flags. These values use bitwise flags to allow efficient checking of multiple states with a single operation. Each state is represented by a unique power of 2 to ensure clear bitwise operations.

const Status = {
  INIT: 1,         // Initial state when thread is first created
  READY: 2,        // Ready state when thread is prepared to run
  ACTIVE: 4,       // Active state when thread is currently executing
  SUCCESS: 8,      // Success state when thread has completed successfully
  ERROR: 16,       // Error state when thread has encountered an error
  COMPLETED: 24,   // Combined state for threads that have completed (SUCCESS | ERROR)
  STARTED: 28,      // Combined state for threads that have started (ACTIVE | COMPLETED)
}
