Class BlockingClientManager

java.lang.Object

com.google.common.util.concurrent.AbstractIdleService

org.bitcoinj.net.BlockingClientManager

All Implemented Interfaces:

com.google.common.util.concurrent.Service, ClientConnectionManager

public class BlockingClientManager
extends com.google.common.util.concurrent.AbstractIdleService
implements ClientConnectionManager

A thin wrapper around a set of BlockingClients.

Generally, using NioClient and NioClientManager should be preferred over BlockingClient and BlockingClientManager as they scale significantly better, unless you wish to connect over a proxy or use some other network settings that cannot be set using NIO.
