Interface EventSamples::StockManager

The StockManager component allows a client to request notification of changes in the value of selected stocks. When a stock value changes, all clients that have requested notification of changes in that stock are notified (asynchronously).

How to run the StockManager demo:

• Ensure that the JDK 'java' runtime is in the current executable path, and CLASSPATH includes $JAGUAR/html/classes.
• Run "java com.sybase.jaguar.sample.events.StockClient" to see the usage. This program can be used to register interest in a particular stock or to wait for notification.
• Run "java com.sybase.jaguar.sample.events.StockOffice" to see the usage. This program can be used to generate a new stock event.

The hand-coded files used by this sample are as follows:

• StockManagerImpl.java (Java component)
• StockClient.java (Java client application)
• StockOffice.java (Java client application)
• PullStockEvent.java (Thread class for async notification)
• StockEventListener.java (Java Beans style event listener)
• Hashqueue.java (a simple event queue utility class)

All other files used by this sample are Jaguar-generated files.
