Types

type Action

type Action interface {
	Suspend(message string)
	Terminate(message string)
	Wait(message string)
}

Action is that workflow provider can do.

type GeneratorOptions

type GeneratorOptions struct {
	ID            string
	PrePhase      common.WorkflowStepPhase
	StepConvertor func(step v1beta1.WorkflowStep) (v1beta1.WorkflowStep, error)
}

GeneratorOptions is the options for generate task.

type Operation

type Operation struct {
	Suspend    bool
	Terminated bool
}

Operation is workflow operation object.

type TaskDiscover

type TaskDiscover interface {
	GetTaskGenerator(ctx context.Context, name string) (TaskGenerator, error)
}

TaskDiscover is the interface to obtain the TaskGenerator。

type TaskGenerator

type TaskGenerator func(wfStep v1beta1.WorkflowStep, options *GeneratorOptions) (TaskRunner, error)

TaskGenerator will generate taskRunner.

type TaskPostStopHook

type TaskPostStopHook func(ctx wfContext.Context, taskValue *value.Value, step v1beta1.WorkflowStep, phase common.WorkflowStepPhase) error

TaskPostStopHook run after task execution.

type TaskPreStartHook

type TaskPreStartHook func(ctx wfContext.Context, paramValue *value.Value, step v1beta1.WorkflowStep) error

TaskPreStartHook run before task execution.

type TaskRunOptions

type TaskRunOptions struct {
	Data          *value.Value
	PreStartHooks []TaskPreStartHook
	PostStopHooks []TaskPostStopHook
	GetTracer     func(id string, step v1beta1.WorkflowStep) monitorCtx.Context
	RunSteps      func(isDag bool, runners ...TaskRunner) (*common.WorkflowStatus, error)
}

TaskRunOptions is the options for task run.

type TaskRunner

type TaskRunner interface {
	Name() string
	Pending(ctx wfContext.Context) bool
	Run(ctx wfContext.Context, options *TaskRunOptions) (common.WorkflowStepStatus, *Operation, error)
}

TaskRunner is a task runner.
