clientAPI

Class Client

java.lang.Object

clientAPI.Client

public class Client
extends Object

This example shows how to use the client APIs to create two different types of clients that will connect to a cache server.

See the README.html for instructions on how to run the example.

See the source code in Client.java to see how to use the client APIs.

The two types of clients are:

1. A client acting as a publisher. It does not want to store any data in the client cache but simply send it to the server.
2. A client acting as a subscriber. It just wants events any time a publisher adds some data.

Method Detail

connectStandalone

public static com.gemstone.gemfire.cache.client.ClientCacheFactory connectStandalone(String name)

Sets up this client's ClientCache. Since we are using a ClientCache, we can omit a few properties we would usually provide (mcast-port, locators, etc).

Logging and statistics are enabled because it is best to have these recorded.

cache-xml-file is disabled since this example uses API to create the client's pools and regions.

An alternative would be to use a gemfire.properties file containing: log-file=name.log statistic-archive-file=name.gfs statistic-sampling-enabled=true cache-xml-file= and to construct a default ClientCacheFactory, allowing GemFire to load the properties from the property file.

Parameters:

name - the base name to use for the log file and stats file.

Returns:

the created ClientCache

main

public static void main(String[] args)
                 throws Exception

See the the README.html for instructions on how to run the class from the command line.

Parameters:

args - must contain one element whose value is "publisher" or "subscriber".

Throws:

Exception
