org.apache.catalina.tribes.transport.bio
Class BioSender

java.lang.Object
  org.apache.catalina.tribes.transport.AbstractSender
      org.apache.catalina.tribes.transport.bio.BioSender

All Implemented Interfaces:: DataSender

public class BioSender
extends AbstractSender
implements DataSender
extends AbstractSender
implements DataSender

Send cluster messages with only one socket. Ack and keep Alive Handling is supported

Since:: 5.5.16
Author:: Peter Rossbach, Filip Hanik

Field Summary
`protected XByteBuffer`	`ackbuf`
`protected static StringManager`	`sm` The string manager for this package.

Constructor Summary
`BioSender()`

Method Summary
`protected void`	`closeSocket()` close socket
`void`	`connect()` Connect other cluster member receiver
`void`	`disconnect()` disconnect and close socket
`java.lang.String`	`getInfo()` Return descriptive information about this implementation and the corresponding version number, in the format `<description>/<version>`.
`protected void`	`openSocket()` open real socket and set time out when waitForAck is enabled is socket open return directly
`protected void`	`pushMessage(byte[] data, boolean reconnect, boolean waitForAck)` Push messages with only one socket at a time Wait for ack is needed and make auto retry when write message is failed.
`void`	`sendMessage(byte[] data, boolean waitForAck)` Send message
`java.lang.String`	`toString()` Name of this SockerSender
`protected void`	`waitForAck()` Wait for Acknowledgement from other server FIXME Please, not wait only for three characters, better control that the wait ack message is correct.

Return descriptive information about this implementation and the corresponding version number, in the format <description>/<version>.

connect

public void connect()
             throws java.io.IOException

Connect other cluster member receiver

Specified by:: connect in interface DataSender
Specified by:: connect in class AbstractSender

Throws:: java.io.IOException
See Also:: DataSender.connect()

disconnect

public void disconnect()

disconnect and close socket

Specified by:: disconnect in interface DataSender
Specified by:: disconnect in class AbstractSender

See Also:: DataSender.disconnect()

sendMessage

public void sendMessage(byte[] data,
                        boolean waitForAck)
                 throws java.io.IOException

Send message

Throws:: java.io.IOException

toString

public java.lang.String toString()

Name of this SockerSender

Overrides:: toString in class java.lang.Object

openSocket

protected void openSocket()
