Detailed Description

This is a specialization of the protobuf class ZeroCopyOutputStream. The principle is to give the proto layer one buffer of bytes at a time that it can use to serialize the next portion of the message, with the option to "backup" if more buffer is given than required at the last buffer.

Constructor & Destructor Documentation

◆ ProtoBufferWriter()

grpc::ProtoBufferWriter::ProtoBufferWriter	(	ByteBuffer *	byte_buffer,
		int	block_size,
		int	total_size
	)

inline

Constructor for this derived class

Parameters

[out]	byte_buffer	A pointer to the grpc::ByteBuffer created
	block_size	How big are the chunks to allocate at a time
	total_size	How many total bytes are required for this proto

Create an empty raw byte buffer and look at its underlying slice buffer

Member Function Documentation

◆ BackUp()

void grpc::ProtoBufferWriter::BackUp ( int count )

inlineoverride

Backup by count bytes because Next returned more bytes than needed (only used in the last buffer). count must be less than or equal too the last buffer returned from next.
