VertexTypes maps a vertex type to its kind and a function for creation of a new client.Object.

Functions ¶

func New ¶

func New(logger logr.Logger, client client.Client, forSelfHostedShoots bool) *graph

New creates a new graph interface for tracking resource dependencies.

func NewDebugHandler ¶

func NewDebugHandler(graph *graph) http.HandlerFunc

NewDebugHandler creates a new HTTP handler for debugging the resource dependency graph.

Types ¶

type Interface ¶

type Interface interface {
	// Setup registers the event handler functions for the various resource types.
	Setup(ctx context.Context, c cache.Cache) error
	// HasVertex returns true when the given vertex exists in the graph.
	HasVertex(vertexType VertexType, vertexNamespace, vertexName string) bool
	// HasPathFrom returns true when there is a path from <from> to <to>.
	HasPathFrom(fromType VertexType, fromNamespace, fromName string, toType VertexType, toNamespace, toName string) bool
	// Nodes returns all nodes of the graph.
	Nodes() gonumgraph.Nodes
	// Visit loops over all nodes in the graph.
	Visit(nodes gonumgraph.Nodes, visitor func(gonumgraph.Node))
}

Interface is used to track resources dependencies.

type KindObject ¶

type KindObject struct {
	Kind          string
	NewObjectFunc func() client.Object
}

KindObject contains the object kind and a function for creating a new client.Object.

type Vertex ¶

type Vertex struct {
	Type      VertexType
	Namespace string
	Name      string
	// contains filtered or unexported fields
}

Vertex contains the type, namespace, and name of a vertex in the graph.

func (*Vertex) ID ¶

func (v *Vertex) ID() int64

ID returns the unique identifier of the vertex.

func (*Vertex) String ¶

func (v *Vertex) String() string

String returns the string representation of the vertex, which includes its type, namespace, and name.
