Methods

addDependency

▸ addDependency(source, target): void

Add target as a direct dependency of source.

Parameters

---

getDependenciesForCollection

▸ getDependenciesForCollection(resource, collection): DependencyGraphResource[]

Get dependencies from resource that is of collection. This function traverses from bottom to up, using dependecyFor.

Parameters

Name	Type
resource	DependencyGraphResource
collection	string

Returns

DependencyGraphResource[]

Overrides

DependencyGraphBase.getDependenciesForCollection

Defined in

src/dependency-graph/in-memory.ts:203

---

getDependenciesOfCollection

▸ getDependenciesOfCollection(resource, collection): DependencyGraphResource[]

Get dependencies of resource that is of collection

Parameters

Name	Type

collection	string

Returns

DependencyGraphResource[]

Overrides

DependencyGraphBase.getDependenciesOfCollection

Defined in

src/dependency-graph/in-memory.ts:259

---

getDependencyGraphNode

▸ getDependencyGraphNode(resource): undefined | DependencyGraphNode

Extracts the node from the dependency graph.

Parameters

Name	Type
resource	DependencyGraphResource

Returns

undefined | DependencyGraphNode

DependencyGraphNode, if doesn't exists it will be undefined

Defined in

src/dependency-graph/in-memory.ts:20

---

getDependsOnCollection

▸ getDependsOnCollection(resource, collection): DependencyGraphResource[]

Get dependencies from resource that is of collection. This function traverses from up to bottom, using dependentOn.

Parameters
