Functions

func EmptyEventType 

func EmptyEventType() *eventingv1beta3.EventType

Types

type AttributesFilterTransform added in v0.42.0 

type AttributesFilterTransform struct {
	Filter *eventingv1.TriggerFilter
}

func (*AttributesFilterTransform) Apply added in v0.42.0 

func (aft *AttributesFilterTransform) Apply(et *eventingv1beta3.EventType, tfc TransformFunctionContext) (*eventingv1beta3.EventType, TransformFunctionContext)

Apply will apply the transform to a given input eventtype. This will "narrow" the eventtype to represent only events which could pass the attribute filter. For example, if the "type" attribute was not yet set on the eventtype, but the filter requires "type"="example.event.type", then after this filter the eventtype would have the attribute definition for "type"="example.event.type". Additionally, if an eventtype can not be narrowed this returns nil. For example using the filter from the earlier example, if the "type" was already set to "other.event.type" then the eventtype would not be compatible.
