Class ProtoReader

java.lang.Object

dev.lavalink.youtube.sabr.protobuf.ProtoReader

public class ProtoReader
extends Object

A minimal protocol buffers decoder that iterates over the fields of a single message. Only the subset of functionality required to parse SABR responses is implemented.

Usage: repeatedly call readTag() until it returns -1, inspecting getFieldNumber() and getWireType(), then pulling the value with the relevant read* method (or skip() to ignore the field).
