PROTOC

The PROTOC function builds a PROTO instance from a protobuf descriptor or protobuf syntax. The PROTO instance describes a set of Protocol Buffers messages.

A PROTO instance is needed to serialize and deserialize data to/from Protocol Buffers.

The input to the PROTOC function is a serialized protobuf FileDescriptorSet as produced by invoking the protoc command in the following way:

protoc --include_imports --descriptor_set_out=/path/to/FileDescriptorSet.file file.proto

or a STRING containing a textual description as described on the Protocol Buffers website.

The content of the produced FileDescriptorSet.file converted to a byte array will serve as the desc parameter in the call to PROTOC.
