Class BaseGenericBinaryMessageReaderImpl<HK,HV>

java.lang.Object

io.cloudevents.core.message.impl.BaseBinaryMessageReader

io.cloudevents.core.message.impl.BaseGenericBinaryMessageReaderImpl<HK,HV>

Type Parameters:

HK - Header key type

HV - Header value type

All Implemented Interfaces:

MessageReader, StructuredMessageReader, CloudEventReader

public abstract class BaseGenericBinaryMessageReaderImpl<HK,HV>
extends BaseBinaryMessageReader

This class implements a Binary MessageReader, providing common logic to most protocol bindings which supports both Binary and Structured mode. Content-type is handled separately using a key not prefixed with CloudEvents header prefix.

Method Detail

read

public <T extends CloudEventWriter<V>,V> V read(CloudEventWriterFactory<T,V> writerFactory)

                                                IllegalStateException

Description copied from interface: MessageReader

Visit the message as binary encoded event using the provided visitor factory.

Parameters:

writerFactory - a factory that generates a visitor starting from the SpecVersion of the event

Throws:

CloudEventRWException - if something went wrong during the visit.

IllegalStateException - if the message is not in binary encoding.

readAttributes

public void readAttributes(CloudEventAttributesWriter writer)
                    throws RuntimeException

Description copied from interface: MessageReader

Visit the message attributes as binary encoded event using the provided visitor.

Parameters:

writer - Attributes visitor

Throws:

RuntimeException
