Types

type AzureEventHubs

type AzureEventHubs struct {
	// contains filtered or unexported fields
}

AzureEventHubs allows sending/receiving Azure Event Hubs events. This is an abstract class used by both the pubsub and binding components.

func NewAzureEventHubs

func NewAzureEventHubs(logger logger.Logger, isBinding bool) *AzureEventHubs

NewAzureEventHubs returns a new Azure Event hubs instance.

func (*AzureEventHubs) Close

func (aeh *AzureEventHubs) Close() (err error)

func (*AzureEventHubs) EventHubName

func (aeh *AzureEventHubs) EventHubName() string

EventHubName returns the parsed eventHub property from the metadata. It's used by the binding only.

func (*AzureEventHubs) GetBindingsHandlerFunc

func (aeh *AzureEventHubs) GetBindingsHandlerFunc(topic string, getAllProperties bool, handler bindings.Handler) HandlerFn

GetBindingsHandlerFunc returns the handler function for bindings messages

func (*AzureEventHubs) GetBulkPubSubHandlerFunc

func (aeh *AzureEventHubs) GetBulkPubSubHandlerFunc(topic string, getAllProperties bool, handler pubsub.BulkHandler) HandlerFn

GetPubSubHandlerFunc returns the handler function for bulk pubsub messages.

func (*AzureEventHubs) GetPubSubHandlerFunc

func (aeh *AzureEventHubs) GetPubSubHandlerFunc(topic string, getAllProperties bool, handler pubsub.Handler) HandlerFn

GetPubSubHandlerFunc returns the handler function for pubsub messages

func (*AzureEventHubs) Init

func (aeh *AzureEventHubs) Init(metadata map[string]string) error

Init connects to Azure Event Hubs.

func (*AzureEventHubs) Publish

func (aeh *AzureEventHubs) Publish(ctx context.Context, topic string, messages []*azeventhubs.EventData, batchOpts *azeventhubs.EventDataBatchOptions) error

Publish a batch of messages.

func (*AzureEventHubs) Subscribe

func (aeh *AzureEventHubs) Subscribe(subscribeCtx context.Context, config SubscribeConfig) error

Subscribe receives data from Azure Event Hubs in background.
