Class PoolTcpEndpoint

java.lang.Object
  org.apache.tomcat.util.net.PoolTcpEndpoint

public class PoolTcpEndpoint

extends java.lang.Object

Handle incoming TCP connections. This class implement a simple server model: one listener thread accepts on a socket and creates a new worker thread for each incoming connection. More advanced Endpoints will reuse the threads, use queues, etc.

getConnectionHandler

public TcpConnectionHandler getConnectionHandler()

isRunning

public boolean isRunning()

isPaused

public boolean isPaused()

setBacklog

public void setBacklog(int backlog)

Allows the server developer to specify the backlog that should be used for server sockets. By default, this value is 100.

getBacklog

getSoTimeout

public int getSoTimeout()

setSoTimeout

public void setSoTimeout(int i)

getServerSoTimeout

public int getServerSoTimeout()

setServerSoTimeout

public void setServerSoTimeout(int i)

initEndpoint
