func (*HookController) KubernetesSnapshots 

func (hc *HookController) KubernetesSnapshots() map[string][]ObjectAndFilterResult

KubernetesSnapshots returns a 'full snapshot': all snapshots for all registered kubernetes bindings. Note: no caching as in UpdateSnapshots because KubernetesSnapshots used for non-combined binding contexts.

func (*HookController) UpdateSnapshots 

func (hc *HookController) UpdateSnapshots(context []BindingContext) []BindingContext

UpdateSnapshots ensures fresh consistent snapshots for combined binding contexts.

It uses caching to retrieve snapshots for a particular binding name only once. This caching is important for Synchronization and self-includes: Combined "Synchronization" binging contexts or "Synchronization" with self-inclusion may require several calls to Snapshot*() methods, but objects may change between these calls. 

type KubernetesBindingToMonitorLink struct {
	MonitorId     string
	BindingConfig OnKubernetesEventConfig
}

KubernetesBindingToMonitorLink is a link between a binding config and a Monitor.

	Crontab     string
	// Useful fields to create a BindingContext
	IncludeSnapshots []string
	AllowFailure     bool
	QueueName        string
	Group            string
}
