func EPhaseString added in v0.7.0 

func EPhaseString(s string) (EPhase, error)

EPhaseString retrieves an enum value from the enum constants string name. Throws an error if the param is not part of the enum.

func EPhaseValues added in v0.7.0 

func EPhaseValues() []EPhase

EPhaseValues returns all values of the enum

func (EPhase) IsAEPhase added in v0.7.0 

func (i EPhase) IsAEPhase() bool

IsAEPhase returns "true" if the value is listed in the enum definition. "false" otherwise

func (EPhase) IsTerminal added in v0.1.13 

func (p EPhase) IsTerminal() bool

func (EPhase) String added in v0.1.13 

func (i EPhase) String() string

type ExecutionInfo added in v0.1.13 

type ExecutionInfo struct {
	DynamicNodeInfo  *DynamicNodeInfo
	WorkflowNodeInfo *WorkflowNodeInfo

type Node added in v0.1.13 

type Node interface {
	// Method to indicate that finalize is required for this handler
	FinalizeRequired() bool

	// Setup should be called, before invoking any other methods of this handler in a single thread context
	Setup(ctx context.Context, setupContext SetupContext) error

	// Core method that should handle this node
	Handle(ctx context.Context, executionContext NodeExecutionContext) (Transition, error)

	// This method should be invoked to indicate the node needs to be aborted.
	Abort(ctx context.Context, executionContext NodeExecutionContext, reason string) error

	// This method is always called before completing the node, if FinalizeRequired returns true.
	// It is guaranteed that Handle -> (happens before) -> Finalize. Abort -> finalize may be repeated multiple times
	Finalize(ctx context.Context, executionContext NodeExecutionContext) error

Interface that should be implemented for a node type.
