initialize

public void initialize(java.lang.String id,
                       TableProviderControl helper,
                       TableProviderParameters parameters,

                throws LiveViewException

Description copied from interface: TableProvider

An instance of your class will be initialized with the parameters that were defined in the LVConf.

Specified by:

initialize in interface TableProvider

Parameters:

id - The id by which this TableProvider is declared

helper - Used to control the life cycle of the table

parameters - Allows parameters supplied in LVCONFs to be passed to the table implementation

mapper - Provides a means to translate tables names based on LVCONF configuration

Throws:

LiveViewException

start

public void start()
           throws LiveViewException,
                  java.lang.InterruptedException

Description copied from interface: TableProvider

You should connect to your server successfully before returning from this call. Once you return, the failedAttemptsCount associated with your TableProvider will be cleared, so don't return until you feel that some measure of success was achieved. Note that a new thread is created for the call to this method, so if you need to poll your server, you can simply not return from this method. However, if this is the case, then you should call the clearRetryCount() method of the TableProviderControl once you have successfullly connected. If you are unable to connect with your back end, or if you lose the connection in a polling situation, throw a LiveViewException out of this method. If you are polling the back end, you will get an interrupt from your Thread.sleep() if your TableProvider is being closed. You can just let it throw out of the method or you can catch it, clean up, and rethrow it.

Specified by:

start in interface TableProvider

Throws:

LiveViewException

java.lang.InterruptedException

createDummyCatalogedTable

public static CatalogedTable createDummyCatalogedTable(java.lang.String tableId)

shutdown

public void shutdown()

Description copied from interface: TableProvider

When this is called, you should close threads and do whatever else is necessary to clean up. This means either that your provider was shut down via a service call, or else LiveView itself is shutting down.

Specified by:

shutdown in interface TableProvider
