is an option for asynchronous operations that specifies the content of associations to which to apply handler functions.

Details

  • The following are typical settings for HandlerFunctionsKeys:
  • Automatictry to include only elements required by handler functions
    Allinclude all available elements
    {"key1","key2",}include particular keys
  • The keys available with particular tasks are listed under the functions that submit the tasks.
