Class NettyChannelFactory

java.lang.Object

net.devh.boot.grpc.client.channelfactory.AbstractChannelFactory<NettyChannelBuilder>

net.devh.boot.grpc.client.channelfactory.NettyChannelFactory

All Implemented Interfaces:

AutoCloseable, GrpcChannelFactory

public class NettyChannelFactory
extends AbstractChannelFactory<NettyChannelBuilder>

This channel factory creates and manages netty based GrpcChannelFactorys.

This class utilizes connection pooling and thus needs to be closed after usage.
