Protobuf

• Protobuf
  • Basic Protobuf
    • BuildPartial and partial messages

Basic Protobuf

• Google's docs - https://developers.google.com/protocol-buffers/docs/proto

• message - like a class
• required
• optional
• repeated
• Map - can be made with a sub-message and then repeated
• enums - for enum entries should prefix by enum type name to ensure uniqueness (enum entries are like globals)

BuildPartial and partial messages

• MessageLiteOrBuilder.isInitialized()
  • Checks if we have all required fields before building
  • Avoids a RUNTIME exception (UninitializedMessageException) if missing required fields.
• buildPartial() - builds a partial message, ignoring any missing required fields
