Public Member Methods

final attach ()
 This method is called when Qorus starts working on a workflow order data instance; it in turn calls attachImpl() which can be overridden in subclasses. More...
 
final detach (string status, *string external_order_instanceid)
 This method is called when the workflow order data instance status is committed to the database; it in turn calls detachImpl() which can be overridden in subclasses. More...
 
final oneTimeInit ()
 This method is executed once when the workflow execution instance starts or is reset; it in turn calls oneTimeInitImpl() which can be overridden in subclasses. More...
 
final errorHandler (string errcode, *hash< auto > errinfo, auto opt)
 This method is called when errors are raised; it in turn calls errorHandlerImpl() which can be overridden in subclasses. More...

Member Function Documentation

◆ attach()

final OMQ::UserApi::Workflow::QorusWorkflow::attach ( )

This method is called when Qorus starts working on a workflow order data instance; it in turn calls attachImpl() which can be overridden in subclasses.

If any error is raised in the attach method (by calling WorkflowApi::stepError() in Qore code or WorkflowApi.stepError() in Java code) or by throwing an appropriate exception), the workflow order data instance will receive an OMQ::StatError status and the attach operation will fail.

Note
TempData can only be reliably set in the attach method, because a workflow can be restarted from any step after an error. Therefore you cannot ensure that TempData set in other step code will be available when executing the following step, in case an error occurs.

◆ attachImpl()

OMQ::UserApi::Workflow::QorusWorkflow::attachImpl ( )
private

This method is called when Qorus starts working on a workflow order data instance; this method may be overridden in subclasses.

If any error is raised in the attach method (by calling WorkflowApi::stepError() in Qore code or WorkflowApi.stepError() in Java code) or by throwing an appropriate exception), the workflow order data instance will receive an OMQ::StatError status and the attach operation will fail.

Note
TempData can only be reliably set in the attach method, because a workflow can be restarted from any step after an error. Therefore you cannot ensure that TempData set in other step code will be available when executing the following step, in case an error occurs.

◆ detach()

final OMQ::UserApi::Workflow::QorusWorkflow::detach ( string  status,
*string  external_order_instanceid 
)

This method is called when the workflow order data instance status is committed to the database; it in turn calls detachImpl() which can be overridden in subclasses.

Parameters
statusThe status being set for the workflow order data instance, see Workflow, Segment, and Step Status Descriptions
external_order_instanceidThe external key for the workflow data being processed, if any exists, otherwise NOTHING

The first argument passed to the method is the workflow order data instance's status (status descriptions) that will be written to the database. The second argument passed is the external order instance ID, if any exists.

◆ detachImpl()

OMQ::UserApi::Workflow::QorusWorkflow::detachImpl ( string  status,
*string  external_order_instanceid 
)
private

This method is called when the workflow order data instance status is committed to the database; this method may be overridden in subclasses.

Parameters
statusThe status being set for the workflow order data instance, see Workflow, Segment, and Step Status Descriptions
external_order_instanceidThe external key for the workflow data being processed, if any exists, otherwise NOTHING

The first argument passed to the method is the workflow order data instance's status (status descriptions) that will be written to the database. The second argument passed is the external order instance ID, if any exists.

◆ errorHandler()

final OMQ::UserApi::Workflow::QorusWorkflow::errorHandler ( string  errcode,
*hash< auto >  errinfo,
auto  opt 
)

This method is called when errors are raised; it in turn calls errorHandlerImpl() which can be overridden in subclasses.

Parameters
errcodethe error code string (ex: "QORE-EXCEPTION")
errinfothis parameter will only be present if the error has been defined by as a workflow error; if so, the hash should have at least the following keys (key names in square brackets (i.e. [name]) are optional):
  • desc: description of the error
  • severity: Error Severity Codes
  • status: either OMQ::StatRetry (meaning that the step should be retried) or OMQ::StatError
  • [retry-delay]: the delay in seconds before the error should be retried (only valid when status is OMQ::StatRetry)
  • [business]: if True, this error represents a business error (rather than a technical error); usually implying that there is a problem with the consistency of the order data
optan optional parameter that can be supplied by the workflow when an error is raised, normally a string providing additional information about the error

This method allows the workflow to do external logging or to take custom actions when errors are raised.

The default implementation in the base class is empty.

◆ errorHandlerImpl()

OMQ::UserApi::Workflow::QorusWorkflow::errorHandlerImpl ( string  errcode,
*hash< auto >  errinfo,
auto  opt 
)
private

This method is called when errors are raised and may be overridden in subclasses.

Parameters
errcodethe error code string (ex: "QORE-EXCEPTION")
errinfothis parameter will only be present if the error has been defined as a workflow error; if so, the hash should have at least the following keys (key names in square brackets (i.e. [name]) are optional):
  • desc: description of the error
  • severity: Error Severity Codes
  • status: either OMQ::StatRetry (meaning that the step should be retried) or OMQ::StatError
  • [retry-delay]: the delay in seconds before the error should be retried (only valid when status is OMQ::StatRetry)
  • [business]: if True, this error represents a business error (rather than a technical error); usually implying that there is a problem with the consistency of the order data
optan optional parameter that can be supplied by the workflow when an error is raised, normally a string providing additional information about the error

This method allows the workflow to do external logging or to take custom actions when errors are raised.

The default implementation in the base class is empty.

◆ oneTimeInit()

final OMQ::UserApi::Workflow::QorusWorkflow::oneTimeInit ( )

This method is executed once when the workflow execution instance starts or is reset; it in turn calls oneTimeInitImpl() which can be overridden in subclasses.

Note
Persistent objects with a high acquisition cost should be acquired in the oneTimeInit() method. Use the WorkflowApi::updateInstanceData() method (in Qore) or the WorkflowApi.updateInstanceData() method (in Java) to save resources acquired, and WorkflowApi::getInstanceData() (in Qore) or the WorkflowApi.getInstanceData() method (in Java) to retrieve the resources during the workflow's execution.

◆ oneTimeInitImpl()

OMQ::UserApi::Workflow::QorusWorkflow::oneTimeInitImpl ( )
private

This method is executed once when the workflow execution instance starts or is reset; this method may be overridden in subclasses.

Note
Persistent objects with a high acquisition cost should be acquired in the oneTimeInit() method. Use the WorkflowApi::updateInstanceData() method (in Qore) or the WorkflowApi.updateInstanceData() method (in Java) to save resources acquired, and WorkflowApi::getInstanceData() (in Qore) or the WorkflowApi.getInstanceData() method (in Java) to retrieve the resources during the workflow's execution.
