Interface Informers

pkg/cache/cache.go:76–97

Informers knows how to create or fetch informers for different group-version-kinds, and add indices to those informers. It's safe to call GetInformer from multiple threads.

	// GetInformerForKind is similar to GetInformer, except that it takes a group-version-kind, instead
	// of the underlying object.
	GetInformerForKind(ctx context.Context, gvk schema.GroupVersionKind, opts ...InformerGetOption) (Informer, error)

	// RemoveInformer removes an informer entry and stops it if it was running.

	// It blocks.
