Class Track

Namespace

Typhon.Engine

Assembly

Typhon.Engine.dll

An ordered, tagged container of Dags — the top level of the runtime partitioning hierarchy (Engine → Track → DAG → Phase → System).

public sealed class Track

Inheritance

object

Track

Inherited Members

object.GetType()

object.ToString()

object.Equals(object)

object.Equals(object, object)

object.ReferenceEquals(object, object)

object.GetHashCode()

Remarks

Track order is the execution sequence: every DAG of track N completes before any DAG of track N+1 begins (a coarse engine-level barrier). Within a track, DAGs are independent.

A track carries an open tag set (e.g. EngineTag). No engine behaviour keys off a track's Name; tooling visibility keys off Tags. The three built-in tracks — Engine-Pre, PublicTrack, Engine-Post — are created by Create(RuntimeOptions).

Fields

EngineTag

The engine tag — marks tracks that hold engine-internal DAGs (Engine-Pre, Engine-Post).

public const string EngineTag = "engine"

Field Value

string

Properties

Dags

DAGs declared on this track, in declaration order.

public IReadOnlyList<Dag> Dags { get; }

Property Value

IReadOnlyList<Dag>

IsEngine

True when this track carries the EngineTag — it holds engine-internal DAGs not surfaced as user systems.

public bool IsEngine { get; }

Property Value

bool

Name

Track name. Diagnostic only — no engine behaviour keys off it.

public string Name { get; }

Property Value

string

OrderIndex

Execution order index. Lower-indexed tracks run to completion before higher-indexed ones begin. Reassigned by DeclareTrack(string, params string[]) as app tracks are slotted in, so it always equals the track's position.

public int OrderIndex { get; }

Property Value

int

Tags

The track's open tag set.

public IReadOnlyCollection<string> Tags { get; }

Property Value

IReadOnlyCollection<string>

Methods

DeclareDag(string)

Declares a new Dag on this track. A DAG that declares no named phases gets a single implicit phase — .After() edges suffice to order a trivial DAG.

public Dag DeclareDag(string name)

Parameters

name string

DAG name — must be unique across the whole schedule.

Returns

Dag

HasTag(string)

True when tag is present in this track's tag set.

public bool HasTag(string tag)

Parameters

tag string

Returns

bool
