- Classes in com.fasterxml.jackson.dataformat.protobuf.schema used by com.fasterxml.jackson.dataformat.protobuf
  Class and Description
  ProtobufField
  ProtobufMessage
  ProtobufSchema A `FormatSchema` implementation for protobuf, bound to specific root-level `ProtobufMessage`, and useful for reading/writing protobuf content that encodes instance of that message.
  ProtobufSchemaLoader Class used for loading protobuf definitions (from .proto files or equivalent sources), to construct schema needed for reading or writing content.

  Class and Description
  EnumLookup Helper class used for doing efficient lookups of protoc enums given enum name caller provides.
  FieldLookup Helper class used for cases where `ProtobufField` instances need to be looked up by name.
  FieldType Set of distinct types parsed from protoc, as unified considering that Java makes no distinction between signed and unsigned types.
  NativeProtobufSchema Helper class used for wrapping a "raw" protobuf schema (as read by "protoparser" library); and used as input for creating specific `ProtobufSchema` to use for reading/writing protobuf encoded content
  ProtobufEnum
  ProtobufField
  ProtobufMessage
  ProtobufSchema A `FormatSchema` implementation for protobuf, bound to specific root-level `ProtobufMessage`, and useful for reading/writing protobuf content that encodes instance of that message.
  ProtobufSchemaLoader Class used for loading protobuf definitions (from .proto files or equivalent sources), to construct schema needed for reading or writing content.
  TypeResolver Stateful class needed to properly resolve type definitions of protobuf message (and related types); some complexity coming from possible nested nature of definitions.
