Overview

Represents a single node in a dependency graph

A node can represent either a step template (for template graphs) or a workflow step instance (for runtime graphs).

Examples:

Template graph node

node = GraphNode.new(
  id: 'validate_payment',
  name: 'validate_payment',
  type: 'step_template',
  metadata: { retryable: true, retry_limit: 3 }
)

Runtime graph node

node = GraphNode.new(
  id: '12345',
  name: 'validate_payment',
  type: 'workflow_step',
  state: 'complete',
  readiness_status: { ready_for_execution: false },
  metadata: { step_class: 'ValidatePaymentStep' }
)
