org.apache.tomcat.util.net
Class PoolTcpEndpoint

java.lang.Object
  extended by org.apache.tomcat.util.net.PoolTcpEndpoint
All Implemented Interfaces:
java.lang.Runnable

public class PoolTcpEndpoint
extends java.lang.Object
implements java.lang.Runnable

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

public int getBacklog()

setServerTimeout

By default this value is 1000ms.


getTcpNoDelay

public boolean getTcpNoDelay()

setTcpNoDelay

public void setTcpNoDelay(boolean b)

getSoLinger

public int getSoLinger()

setSoLinger

public void setSoLinger(int i)

getSoTimeout

public int getSoTimeout()

setSoTimeout

public void setSoTimeout(int i)

getServerSoTimeout

public int getServerSoTimeout()

setServerSoTimeout

public void setServerSoTimeout(int i)

getStrategy

public java.lang.String getStrategy()

setStrategy

public void setStrategy(java.lang.String strategy)

getCurrentThreadCount

public int getCurrentThreadCount()

getCurrentThreadsBusy

public int getCurrentThreadsBusy()

initEndpoint

public void initEndpoint()
                  throws java.io.IOException,
                         java.lang.InstantiationException
Throws:
java.io.IOException
java.lang.InstantiationException

startEndpoint

java.lang.InstantiationException

pauseEndpoint

public void pauseEndpoint()

resumeEndpoint

public void resumeEndpoint()

stopEndpoint

public void stopEndpoint()

closeServerSocket

protected void closeServerSocket()

unlockAccept

protected void unlockAccept()

run

public void run()
The background thread that listens for incoming TCP/IP connections and hands them off to an appropriate processor.

Specified by:
run in interface java.lang.Runnable
