Functions

func CheckVars

func CheckVars(ctx context.Context, eng expression.Engine, state *model.WorkflowState, el *model.Element) error

CheckVars checks for missing variables expected in a result

func Decode

func Decode(ctx context.Context, vars []byte) (model.Vars, error)

Decode decodes a go binary object containing workflow variables.

func Encode

func Encode(ctx context.Context, vars model.Vars) ([]byte, error)

Encode encodes the map of workflow variables into a go binary to be sent across the wire.

func InputVars

func InputVars(ctx context.Context, eng expression.Engine, oldVarsBin []byte, newVarsBin *[]byte, el *model.Element) error

InputVars returns a set of variables matching an input requirement after transformation through expressions contained in an element.

func OutputVars

func OutputVars(ctx context.Context, eng expression.Engine, newVarsBin []byte, mergeVarsBin *[]byte, transform map[string]string) error

OutputVars merges one variable set into another based upon any expressions contained in an element.
