Types

type ActiveBoundaryTrace

type ActiveBoundaryTrace struct {
	Start bool
	Node  schema.FlowNodeInterface
}

func (ActiveBoundaryTrace) TraceInterface

func (b ActiveBoundaryTrace) TraceInterface()

type ActiveTaskTrace

type ActiveTaskTrace interface {
	tracing.ITrace
	Execute()
}

ActiveTaskTrace describes common channel handler for all tasks

type Activity

type Activity interface {
	flow_node.IFlowNode
	// Cancel initiates a cancellation of activity and returns a channel
	// that will signal a boolean (`true` if cancellation was successful,
	// `false` otherwise)
	Cancel() <-chan bool
}

Activity is a generic interface to flow nodes that are activities

type Constructor

type Constructor = func(*flow_node.Wiring) (node Activity, err error)

type Harness

type Harness struct {
	*flow_node.Wiring
	// contains filtered or unexported fields
}

func NewHarness

func NewHarness(ctx context.Context,
	wiring *flow_node.Wiring,
	element *schema.FlowNode,
	idGenerator id.IGenerator,
	constructor Constructor,
