type Config ¶

type Config struct {
	Filters        []filtertypes.FilterMeta
	Actions        []actiontypes.ActionMeta
	FilterRegistry *filterregistry.Registry
	ActionRegistry *actionregistry.Registry
	Executor       *executor.Executor
}

type EventHandler ¶

type EventHandler func(sourceType string, event interface{}, data interface{}) error

EventHandler is given to Source to be called. Source is responsible to call this function.

sourceType is what type the Source is.

event is what event happened, containing a brief event object. Do not include complex objects in it. For example, a k8s-resource-watcher Source may contain what event happened (create, update, delete) in it.

data is the detailed event, for machines to process, e.g. passed to filters to do filtering . You may put complex objects in it. For example, a k8s-resource-watcher Source may contain the entire object that is changed in it.

func New() EventHandler

func NewFromConfig(c Config) EventHandler

func (e EventHandler) AddHandlerAfter(eh EventHandler) EventHandler
