public class LateralTCPSender
extends Object

This class is based on the log4j SocketAppender class. I'm using a different repair structure, so it is significantly different.

Constructor Detail

LateralTCPSender

public LateralTCPSender(ITCPLateralCacheAttributes lca)
                 throws IOException

Constructor for the LateralTCPSender object.

Parameters:

lca -

Throws:

IOException

Method Detail

init

protected void init(String host,
                    int port)
             throws IOException

Creates a connection to a TCP server.

Parameters:

host -

port -

Throws:

IOException

send

public <K,V> void send(LateralElementDescriptor<K,V> led)
                throws IOException

Sends commands to the lateral cache listener.

Parameters:

led -

Throws:

IOException

sendAndReceive

public <K,V> Object sendAndReceive(LateralElementDescriptor<K,V> led)
                            throws IOException

Sends commands to the lateral cache listener and gets a response. I'm afraid that we could get into a pretty bad blocking situation here. This needs work. I just wanted to get some form of get working. However, get is not recommended for performance reasons. If you have 10 laterals, then you have to make 10 failed gets to find out none of the caches have the item.

Parameters:

led -

Returns:

ICacheElement

Throws:

IOException

dispose

public void dispose()
             throws IOException

Closes connection used by all LateralTCPSenders for this lateral connection. Dispose request should come into the facade and be sent to all lateral cache services. The lateral cache service will then call this method.

Throws:

IOException
