const TYPE = 'Demo Task'

const DEMOASSET = {
  name: 'DEMO ASSET',
  execute () {
    console.log('Implement execute aseet logic')
  }
}

const logMethod = function (messageType, message, detailMessage) {
  console.log(messageType, message, detailMessage)
}

class DemoTask extends SystemTask {
  const REQUIREASYNCEPROCESS = true
  constructor () {
    super(TYPE, REQUIREASYNCEPROCESS, logMethod)
  }

  async insertPreprocessItemsHandler (task) {
    return [
        { Object.assign({}, DEMOASSET, { name: 'Asset 1' }) },
        { Object.assign({}, DEMOASSET, { name: 'Asset 2' }) }
      ]
  }

  async processHandler (task, processItem) {
    await task.log('info', `execuse`, {Type: task.type, processItem})
    // processItem can be execute method 
    // e.g. await processItem.execute()

    return processItem
  }
}

module.exports = DemoTask
