class ProtoBufferReader

Defined at line 48 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

This is a specialization of the protobuf class ZeroCopyInputStream

The principle is to get one chunk of data at a time from the proto layer,

with options to backup (re-see some bytes) or skip (forward past some bytes)

Public Methods

void ProtoBufferReader (ByteBuffer * buffer)

Constructs buffer reader from

Will set

to non ok

is invalid (the internal buffer has not been initialized).

Defined at line 52 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

void ~ProtoBufferReader ()

Defined at line 63 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

bool Next (const void ** data, int * size)

Give the proto library a chunk of data from the stream. The caller

may safely read from data[0, size - 1].

Defined at line 71 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

Status status ()

Returns the status of the buffer reader.

Defined at line 96 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

void BackUp (int count)

The proto library calls this to indicate that we should back up

bytes that have already been returned by the last call of Next.

So do the backup and have that ready for a later Next.

Defined at line 101 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

bool Skip (int count)

The proto library calls this to skip over

bytes. Implement this

using Next and BackUp combined.

Defined at line 108 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

int64_t ByteCount ()

Returns the total number of bytes read since this object was created.

Defined at line 124 of file ../../third_party/grpc-migrating/src/include/grpcpp/support/proto_buffer_reader.h

bool ReadCord (absl::Cord * cord, int count)

Read the next `count` bytes and append it to the given Cord.

(override is conditionally omitted here to support old Protobuf which

doesn't have ReadCord method)

void set_byte_count (int64_t byte_count)

These protected members are needed to support internal optimizations.

they expose internal bits of grpc core that are NOT stable. If you have

a use case needs to use one of these functions, please send an email to
