* formats: Add support for protobuf format Adds support for the Protocol Buffer CloudEvent format defined at https://github.com/cloudevents/spec/blob/v1.0.1/protobuf-format.md. Compiles the Proto3 file taken from the spec repo into generated Java protobuf classes. These classes are used to convert the SDK representation of a CloudEvent to and from the protobuf format. Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * Address feedback in PR #348 - Adds service file for event format autoloading - Addresses some field access issues - Treats unset fields as omitted - Updates and adds documentation Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * Add missing attribute writer methods for CloudEventBuilders Without these methods, binary attributes are interpreted as Strings instead of byte[]. Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * Added test data files. Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * - Now executes tests related to wire-format files. - Supports V03 dialect Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * - Added new ProtoCloudEventData construct to support proto message based data. - Added some more test files. - When the PR related to binary context attributes is merged we can extend the test use-cases appropriately. Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * - Merged changes related to binary context attributes. - Modified proto format to process binary context attributes - Added CloudEventData varient to hold proto messages (requires tests) - Will add further tests once the failing test is addressed Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * Added test for protobuf data Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * Indicate that v0.3 events are supported by Protobuf Format Even though the protobuf spec came out for v1, the attributes are fairly easily mapped back to v0.3. Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * Add missing comments; fix formatting; minor refactoring Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * Create a full Protobuf CloudEventWriter Converts the ProtoContextWriter class to a ProtoCloudEventWriter class and modifies the format code to use it instead of manually writing data to the output. Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * - Addressed Review Comments. - Introduced a default ProtoDataWrapper - Tests updated. Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * Address Review Comments Signed-off-by: Day, Jeremy(jday) <jday@paypal.com> * Test cleanup and timezone testing This does some tweaking to tests by moving to using assertj and fixing whitespace. It also adds a new test to ensure that timezones are handled correctly. Signed-off-by: Erik Paulson <epaulson@apexclearing.com> * Formatting cleanup - Remove unecessary whitespace - Fix Javadocs - Delete unused code Signed-off-by: Erik Paulson <epaulson@apexclearing.com> Co-authored-by: Day, Jeremy(jday) <jday@paypal.com> |

CloudEvents Protocol Buffers Format
This project provides functionality for the Java SDK to handle the protobuf format.
The protobuf definition file is located in src/main/proto/spec.proto. The file was directly copied from https://github.com/cloudevents/spec/blob/v1.0.1/spec.proto and is built using the Maven proto plugin.
