Functions ¶

func CreateContactSheet ¶ added in v1.1.2120

func CreateContactSheet(ctx context.Context, tasks []*model.TaskSpec) (string, error)

CreateContactSheet creates a contact sheet for a set of tasks.

func DefaultTaskDescription ¶ added in v1.1.2120

func DefaultTaskDescription(taskName string, typ string) string

DefaultTaskDescription returns a default description for a task.

func DefaultTaskParamDescription ¶ added in v1.1.2120

func DefaultTaskParamDescription(paramName string) string

DefaultTaskParamDescription returns a default description for a task parameter.

func Parse ¶

func Parse(ctx context.Context, defaultEngine expression.Engine, name string, rdr io.Reader) (*model.Workflow, error)

Parse parses BPMN, and turns it into a SHAR state machine

func ParseTasks ¶ added in v1.1.2120

func ParseTasks(ctx context.Context, defaultEngine expression.Engine, name string, rdr io.Reader) (serviceTasks map[string]*model.TaskSpec, userTasks map[string]*model.TaskSpec, err error)

ParseTasks parses a workflow and returns the service and user tasks.

Types ¶

type Duration ¶ added in v0.1.74

type Duration struct {
	Y int
	M int
	W int
	D int
	// Time Component
	TH int
	TM int
	TS int
}

Duration represents an ISO8601 Duration https://en.wikipedia.org/wiki/ISO_8601#Durations

func ParseISO8601 ¶ added in v0.1.74

func ParseISO8601(from string) (Duration, error)

ParseISO8601 parses an ISO8601 Duration string.

func (Duration) IsZero ¶ added in v0.1.74

func (d Duration) IsZero() bool

IsZero reports whether d represents the zero Duration, P0D.

func (Duration) Shift ¶ added in v0.1.74

func (d Duration) Shift(t time.Time) time.Time

Shift returns a time.Time, shifted by the Duration from the given start.

NB: Shift uses time.AddDate for years, months, weeks, and days, and so shares its limitations. In particular, shifting by months is not recommended unless the start date is before the 28th of the month. Otherwise, dates will roll over, e.g. Aug 31 + P1M = Oct 1.

Week and Day values will be combined as W*7 + D.

type Navigable ¶ added in v1.1.1913

type Navigable struct {
	Incoming map[string][]*model.Element
	Outgoing map[string][]*model.Element
	Start    []*model.Element
}

Navigable is a helper object for static analysis.

func NewNavigable ¶ added in v1.1.1913

func NewNavigable(ctx context.Context, eles *model.Workflow) (*Navigable, error)

NewNavigable creates a Navigable object from a workflow to assist in static analysis.
