Method Detail

prepare

public EnableTableHandler prepare()
                           throws TableNotFoundException,
                                  TableNotDisabledException,

Description copied from class: EventHandler

Event handlers should do all the necessary checks in this method (rather than in the constructor, or in process()) so that the caller, which is mostly executed in the ipc context can fail fast. Process is executed async from the client ipc, so this method gives a quick chance to do some basic checks. Should be called after constructing the EventHandler, and before process().

Overrides:

prepare in class EventHandler

Returns:

the instance of this class

Throws:

TableNotFoundException

TableNotDisabledException

IOException

toString

public String toString()

Overrides:

toString in class EventHandler

process

public void process()

Description copied from class: EventHandler

This method is the main processing loop to be implemented by the various subclasses.

Specified by:

process in class EventHandler
