Types ¶
type ActionData ¶
type ActionData struct {
// contains filtered or unexported fields
}
ActionData action related data to pass along in a ActionWorkRequest
type ActionResult ¶
type ActionResult struct {
// contains filtered or unexported fields
}
ActionResult is a simple struct to hold the results for an Action
type ActionWorkRequest ¶
type ActionWorkRequest struct {
ReqType RequestType
ID string
// contains filtered or unexported fields
}
ActionWorkRequest describes a Request that Worker should handle
type ActionWorker ¶
type ActionWorker struct {
ID int
Work chan ActionWorkRequest
WorkerQueue chan chan ActionWorkRequest
QuitChan chan bool
// contains filtered or unexported fields
}
A ActionWorker handles WorkRequest, work requests consist of start, restart and resume of FlowInstances
func NewWorker ¶
func NewWorker(id int, runner *DirectRunner, workerQueue chan chan ActionWorkRequest) ActionWorker
NewWorker creates, and returns a new Worker object. Its only argument is a channel that the worker can add itself to whenever it is done its work.
func (ActionWorker) Start ¶
func (w ActionWorker) Start()
Start function "starts" the worker by starting a goroutine, that is an infinite "for-select" loop. This is where all the request are handled
func (ActionWorker) Stop ¶
func (w ActionWorker) Stop()
Stop tells the worker to stop listening for work requests.
Note that the worker will only stop *after* it has finished its work.
type AsyncResultHandler ¶
type AsyncResultHandler struct {
// contains filtered or unexported fields
}
AsyncResultHandler simple ResultHandler to use in the asynchronous case
func (*AsyncResultHandler) Done ¶
func (rh *AsyncResultHandler) Done()
Done implements action.ResultHandler.Done
func (*AsyncResultHandler) HandleResult ¶
func (rh *AsyncResultHandler) HandleResult(results map[string]interface{}, err error)
HandleResult implements action.ResultHandler.HandleResult
type DirectRunner ¶
type DirectRunner struct {
}
DirectRunner runs an action synchronously
func (*DirectRunner) RunAction ¶
func (runner *DirectRunner) RunAction(ctx context.Context, act action.Action, inputs map[string]interface{}) (results map[string]interface{}, err error)
Execute implements action.Runner.Execute
func (*DirectRunner) Start ¶
func (runner *DirectRunner) Start() error
Start will start the engine, by starting all of its workers
func (*DirectRunner) Stop ¶
func (runner *DirectRunner) Stop() error
Stop will stop the engine, by stopping all of its workers
type PooledConfig ¶
type PooledConfig struct {
NumWorkers int `json:"numWorkers"`
WorkQueueSize int `json:"workQueueSize"`
}
PooledConfig is the configuration object for a PooledRunner
type PooledRunner ¶
type PooledRunner struct {
// contains filtered or unexported fields
}
PooledRunner is a action runner that queues and runs a action in a worker pool
func NewPooled ¶
func NewPooled(config *PooledConfig) *PooledRunner
NewPooledRunner create a new pooled
func (*PooledRunner) RunAction ¶
func (runner *PooledRunner) RunAction(ctx context.Context, act action.Action, inputs map[string]interface{}) (results map[string]interface{}, err error)
Execute implements action.Runner.Execute
func (*PooledRunner) Start ¶
func (runner *PooledRunner) Start() error
Start will start the engine, by starting all of its workers
func (*PooledRunner) Stop ¶
func (runner *PooledRunner) Stop() error
Stop will stop the engine, by stopping all of its workers
type RequestType ¶
type RequestType int
RequestType is value that indicates the type of Request
const ( // RtRun denotes a run action request RtRun RequestType = 10 )
type SyncResultHandler ¶
type SyncResultHandler struct {
// contains filtered or unexported fields
}
SyncResultHandler simple result handler to use in synchronous case
func (*SyncResultHandler) Done ¶
func (rh *SyncResultHandler) Done()
Done implements action.ResultHandler.Done
func (*SyncResultHandler) HandleResult ¶
func (rh *SyncResultHandler) HandleResult(resultData map[string]interface{}, err error)
HandleResult implements action.ResultHandler.HandleResult
func (*SyncResultHandler) Result ¶
func (rh *SyncResultHandler) Result() (resultData map[string]interface{}, err error)
Result returns the latest Result set on the handler
