                         String dataSchemaUriBase)

Method Detail

create

public static CloudEventsMaker create(RecordParser parser,
                                      SerializerType contentType,
                                      String dataSchemaUriBase)

Create a concrete CloudEvents maker using the outputs of a record parser. Also need to specify the data content type (that is the serialization format of the data attribute).

Parameters:

parser - the parser of a change record

contentType - the data content type of CloudEvents

dataSchemaUriBase - the URI of the schema in case of Avro; may be null

Returns:
