Method Summary

Modifier and Type	Method and Description
void	cancelScheduledMessage(long sequenceNumber) Cancels the enqueuing of an already sent scheduled message, if it was not already enqueued. This method blocks until the message is sent to the entity. Calling this method is equivalent to calling . For better performance, use async methods.
CompletableFuture<Void>	cancelScheduledMessageAsync(long sequenceNumber) Cancels the enqueuing of an already sent scheduled message, if it was not already enqueued. This is an asynchronous method returning a CompletableFuture which completes when the message is cancelled.
String	getEntityPath() Gets the path of the entity this client is sending messages to or receiving messages from.
String	getTopicName() Get the name of the topic
CompletableFuture<Void>	onClose()
IMessage	peek() reads next the active message without changing the state of the receiver or the message source. The first call to peek() fetches the first active message for this receiver. Each subsequent call fetches the subsequent message in the entity.
IMessage	peek(long fromSequenceNumber) Reads next the active message without changing the state of the receiver or the message source.
CompletableFuture<IMessage>	peekAsync() Asynchronously reads the active messages without changing the state of the receiver or the message source.
